OPEN MIKE Open mike closed at 6:38 p.m. 1 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING JULY 25, 2007 5. ACTION ITEMS A. Main Street Village Concept Plan — Azure Properties — PUD Mr. Asleson presented his staff report to the board. This item has been previously submitted for review. There were issues the developer needed to address before the environmental board could move forward with this project. The issues have since been addressed. Mr. Asleson first reviewed the background information on this Item. He then reviewed the analysis, SWPPP, unique resources, tree preservation, AUAR, landscaping and recommendations. Mr. Asleson commented that their AUAR calculations look reasonable at this time. He stated that Rice Creek Watershed District has issued a conditional approval at this item. It was recommended by the board that Mr. Asleson write a letter to the City of Lino Lakes Engineer addressing the changes being made to the SWPPP. The following are the changes /additions made to the SWPPP: 1. Page 4 of the Main Street Village SWPPP, the words "and city" should be added after the bullet point that states "any dewatering discharge shall be approved per the local LGU requirements. 2. Temporary storm ponds should located on the plan sheets 3. A method of dewatering turbid storm water from temporary storm ponds should be detailed on the plan sheets and approved by the city. 4. Location of the SWPPP and weekly, post rain all event inspection sheets must be located on site and indicated on the plan. 5. All infiltration areas must be protected from compaction and sequenced correctly in order to protect the integrity of the stormwater feature. Protection devices (fences) and sequence dialog must be shown on the plans. 6. Location of a clean out area for concre4te trucks must be indicated on the plans and clearly signed in the field. The following changes /recommendations are made by the Environmental Board as of November 28th, 2007: 1. All stormwater volume and flow designs must be evaluated for conformance to RCWD and AUAR standards. 2. Site access for surface water treatment areas must be shown on the map. 3. Slopes of wetland mitigation areas be changed to conform to the AUAR. 2 DRAFT MINUTES • • • • • • ENVIRONMENTAL BOARD MEETING JULY 25, 2007 4. Recommend 1 -2 inch scrapping the wetland soils in the freeze /thaw situation to control reed canary grass. Also recommend the scraped soils in wetland fill areas be salvaged and stockpiled for use in the wetland mitigation area. 5. In general, there should be a narrative to the Boards and the City Council addressing all of the mitigation strategies presented in the AUAR that effect this development. 6. All infiltration areas and wetland mitigation areas should be seeded with the city native seed mix. The city transitional mix is shown on the plan and this is a good mix between cultural areas and wetland/pond areas. The BWSR U8 mix is shown on the wetland mitigation slopes. A better mix selection from the BWSR choices would be the WI mix. However, I would again recommend the city native pond seed mix for this area, supplemented with flowering native plugs every 10 feet. All biofiltration areas should also be supplemented with flowering plugs. Biofiltration areas planted with the transitional seed mix should have a low - profile height associated with the forbes. All native seed mix areas should be planted by a contractor on the Minnesota Department of Natural Resources list of contractors. The native areas should be maintained for a minimum of 3 years by the approved contractor and if possible burned at the end of 3 years. 7. More trees should be planted particularly in type C and D soils. The C type soils intersect biofiltration pond number 9 and wetland mitigation area 10 on the north side, east side, south side and south west comer. Salix `Golden Curls' is a marginally hardy plant and non - native. The AUAR recommends that water infiltration areas be augmented with large herbaceous woody plant materials such as Aspen and Cottonwoods. Therefore substituting more of these types of species and more abundantly in the type C soil areas is in accordance with the AUAR recommendations. Cottonwoods must be of the non - seeding types. Recommend one tree per 25' O.C. in these type C soil areas. 8. Side slope of the wetland mitigation area be no steeper than 6:1 horizontal to vertical. 9. Site access for maintenance reasons must be shown on the plan for stormwater treatment areas. 10. A letter be written to the City Engineering adding issues to the project Storm Water Pollution Prevention Plan 11. Keep parking stalls down to the minimum allowed by zoning code. Add pervious paving if additional parking stalls are necessary. 12. Lighting should not exceed the city minimum lighting allowed by city code. Canopy lights of the gas station must be flush mounted bulbs that present no glare issues and downward directed. Monuments should be kept to a minimum and minimize light spill. 3 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING JULY 25, 2007 13. Request planning staff review trash and recycling accessibility as they relate to truck movements. 14. No soils may be imported or exported to the site without city approval. Soils hauled in should not be substantially different from soils that were inputted into the stormwater model. Motion: Motion was made by Bor, seconded by Andrzejewski to approve the recommendations and forward to Planning & Zoning. B. Vaughan's First Addition Mr. Asleson stated this item was proposed for platting in 2004. At that time, there was an extensive study (EAW) to look at impacts from proposed development from the north end of Rough Grouse Road to the island in Wards Lake, connected by a bridge. The project was approved at that time. The developer decided not to construct the bridge connection. The landowner (Mr. Vaughan) has proposed developing one lot at the end of Rough Grouse Road. Mr. Asleson presented his staff report. He reviewed site data, natural resources, SWPPP, natural resources inventory, watershed issues, unique resources, landscaping and recommendations. He also reviewed the attachments. Mr. Asleson stated the flood plain does not meet regulations. The developer has an incorrect ordinary high water plan. He stated there is very little room to work on this plan. Ms. O'Dea asked if they have room to build a house. Mr. Asleson stated that the lot area standards may be met if they use both lots. Ms. O'Dea questioned how is the high water verified? Mr. Asleson stated it is the DNR who verify's the high water. The information we have from the developer does not adhere to the DNR's information. Ms. Bor stated there was not a tree preservation plan included. Number 5 under Mr. Asleson's recommendations addressed this issue. If the plan comes back again, it will need this information. The Environmental Board has reviewed this item and finds it incomplete at this time and makes the following recommendations: 1. Possibly move the house to be part of outlot A so it meets the shoreland requirements. 2. No importing or exporting of soils. 3. Include a tree preservation plan. 4 DRAFT MINUTES • • • • ENVIRONMENTAL BOARD MEETING JULY 25, 2007 Motion to approve recommendations indicating that we found application incomplete and forward to Planning and Zoning Board at this time. Motion by Ms. DeHaven and seconded by Ms. Andrzejewski. Motion carried unanimously. 6. DISCUSSION ITEMS A. Comp Plan Update — Mr. Asleson reviewed the Comprehensive Plan Update. He discussed the upcoming open house. Ms. Bor mentioned at this time she is the only member of the Environmental Board who volunteered for the comp plan committee who has been regularly attending meetings. She suggested having another board member attend the comp plan meetings. She suggested that if a member volunteers for a committee outside of the Environmental Board and cannot attend on a regular basis, an alternate or new member should fill the vacancy. She also stated the opportunity to be on the comp plan committed is a great learning experience. It was discussed by Board Members who they will send in place of Kim Brouillet to the CPAP Open House of December 4, 2007. It was decided that Mr. Traylor would attend. B. Preliminary goals 2007 — Mr. Asleson stated before our next meeting members should think about new goals for 2008. He also stated he has an upcoming meeting with an Eagle Scout at the middle school on November 29th, which is one of our 2007 goals. He stated we are participating in comp plan process and in the RMP process which is part the comp plan and is currently being worked on. He asked members to bring suggestions, new ideas or changes to our next meeting. C. TMDL Update Barbara Bor Ms. Bor stated that the public needs to be aware of the issues regarding Total Maximum Daily Load (TMDL). State and federal law states the city is going to have to fix pollutant loading issues within the city. The question was raised about who is subject to adhere to these requirements and who are they directing to fix the problems at this point? It was stated that RCWD is our LGU but the city is called an MS4 and has to adhere to TMDL. That is why we are doing a Resource Management Plan. The question was raised concerning the responsibility of the surrounding cities. Mr. Asleson stated they are responsible for meeting their own TMDL requirements. By law other cities will have to meet standards as well. To help expedite the improvement process there are several options suggested to assist with current problems. One option would 5 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING JULY 25, 2007 be a drawdown which might include a total fish kill or fish gates. Ms. Bor stated that there will be a public hearing and an opportunity to give input. 7. ADJOURN It was noted that the next meeting of the Environmental Board will be on December 19, 2007. There being no further business, Mr. Brown moved to adjourn at 8:25 p.m. Ms. Bor seconded the motion. Motion carried unanimously. Transcribed by: Lisa Hogstad Community Development Secretary 6 DRAFT MINUTES • f • Agenda Item 5A • • Environmental Board Meeting Date: February 27, 2008 Topic: Expenditure Review, Yearly Work Plan for Foxburough Development and Recommendations. Background: Foxburough is a conservation development that set up a stewardship fund to manage natural resources in conservation easements of the development. The Foxburough Stewardship fund was established to provide a funding source for the maintenance, repair and improvement of conservation areas. The Developer contributed $100,000.00 as an endowment to the establishment of the fund. Interest earned each year on the $100,000 is the providing source of funds for scheduled work to be done in Foxburough. In addition, each lot has an annual assessment from the association of $100 for the Conservation fund. Since there are 57 lots in the development, $5700 is contributed each year to the fund. The Association will pay the annual Fund payments for each of the 57 lots within the development to the City on or before January 31 of each year. The first $100 per lot Fund assessment shall be assessed and collected during calendar year 2006 and shall be paid by the Association to the City on or before January 31, 2007. The City is the custodian of the Fund and is responsible for the management of the Fund. There was also $40,000 allocated by the Developer for initial restoration work in the conservation easements during development. As of January 1, 2008, there is approximately $17,000 in the fund to spend. The Association is responsible each year to write a management proposal for the conservation areas, within the scope of yearly budget. This plan must be approved by the City and then the funds are released after completion of the work plan. Mr. Mike Black of North Oaks Realty, and Jason Husveth of Critical Connections have submitted the attached Management Proposal documents for your Consideration. A burn was also done last fall. The cost for this burn was $4,770.00. The burn was within the scope of work described in on page 31 (Attachment 1) of the Foxburough Development Restoration and Management Plan "Restoration and Management Needs and Tasks (Years 1 -5), for Fall 2005 /Spring 2006." This theoretically should have been cleared by the Board but time got short for accomplishing the task and Environmental decided to go forward with it. Analysis: Critical Connections Foxburough Conservation Development, Lino Lakes, Minnesota Restoration and Management Planning for 2007 and 2008 are attached. This document describes work that is within the budget constraints of the endowment fund. Recommendation: Approve the Maintenance Plan for Foxburough for 2007/2008 Attachments 1.

These tasks are consistent with the Foxborough Restoration and Management Plan, developed by CCES in August 2005. The proposed restoration and management tasks will be implemented during the 2008 growing season, and will rely on available funding within the Foxborough Conservation Fund. The following proposed tasks, timelines, costs, and priorities constitute the planned scope of work for 2008 within Foxborough's conservation outlots. Task 1 (prescribed burn) was previously implemented in April 2007, and is included in this scope of work. 2007 Restoration and Management Tasks (Completed): Task 1: Prescribed Burn of Conservation Outlots. A prescribed burn was planned and implemented by Critical Connections Ecological Services in cooperation with Marty Asleson, City of Lino Lakes Natural Resources Specialist. The burn was implemented on April 25, 2008 within approximately 75% of the conservation outlot acreage within the Foxborough conservation development. Accessible wetland and upland habitats were burned successfully. In addition, an adult female Blanding's Turtle was discovered during the prescribed burn, and was re- released after the burn was completed. CCES submitted and invoice for this completed work to the City of Lino Lakes on February 19, 2008 in the amount of $4,770.

CCES will develop specifications and order native seed mixes for inter - seeding into wetland and upland areas needing additional native seed and plant material. Priority areas to be targeted for re- seeding and inter - seeding in 2008 are bare soil areas within stormwater management wetlands and along the edges of established trails. All species will be native and appropriate to the existing and prescribed native habitats being seeding. Seed will be ordered in March and seeding in late March or April. Task 2 Timeline: Task 2 Costs: March through April 2008 $1,500 Seed $3,000 Labor Task 3: Management of Invasive Species. Invasive species occurring within the conservation outlots will be inspected, managed, and treated with appropriate herbicides during the 2008 growing season. Buckthorn seedlings and re- sprouts will be chemically treated with Roundup (Glyphosate) herbicide. Reed canary grass will be treated with a grass - specific herbicide (Sethoxydim) in species diverse areas, or Rodeo (Glyphosate) herbicide in areas with over 90% reed canary grass cover. Invasive cattails, such as narrow leaved cattail and hybrid cattail, will be treated with Rodeo (Glyphosate) herbicide. Invasive species management and herbicide treatments will be prioritized to areas that were burned in 2007, to follow up on this management approach, and will then be implemented in other areas as the budget financial resources allow. Task 3 Timeline: Task 3 Costs: April through October 2008 $1,200 Herbicide $8,500 Labor Task 4: Removal of Damaged Oak Tree. A damaged oak tree within the northeast corner of the Foxborough site will be removed. This tree is located within the conservation area, and is immediately adjacent to the trail. The tree was damaged by wind storms two years ago, and its substantial side -limbs have fallen onto the trail in last year. The tree presents a safety liability and could result in further damage to the adjacent City -owned trail, if left untreated. CCES will fall and remove the tree during the winter months, to reduce the possibility of damage to the trail and ground vegetation (while the ground is frozen).

Introduction Royal Oaks Reality (ROR) retained Critical Connections Ecological Services, Inc. (CCES) to develop a natural resources restoration and management plan for the conservation areas associated with the Foxborough Conservation Development within the City of Lino Lakes, Minnesota. The 51 -acre residential conservation development is located south of Birch Street and east of Deerwood Lane in the southeastern corner of Lino Lakes (Figure 1). Of the 51 acres, approximately 29 acres have been set aside in three outlots as permanent conservation areas, to be restored and managed as natural open space in perpetuity. Furthermore, a public pedestrian trail will be constructed within a trail easement through the outermost conservation area (Outlot A), and will serve to connect existing and proposed regional trail systems throughout the city of Lino Lakes and the greater regional trail system of the Rice Creek Chain of Lakes open space. The residential development consists of 57 residential lots and narrowed residential streets that were designed to cluster housing, reduce overall impervious surfaces, minimize stormwater runoff and maintain site hydrology, and restore and preserve existing natural areas within the development in the form of permanently protected and managed outlots. Conservation areas contained within the outlots will be restored and managed as natural communities consistent with the pre - settlement vegetation of the site, such as oak forests and savannas, lowland hardwood forest, wet meadows, emergent marshes, and dry, mesic, and wet prairies. The inventory and ecological assessment for this report was conducted April through July of 2005, and represents baseline information regarding the natural resources of the site. The site inventory and assessment was designed to document the extent and types of existing vegetation and native plant communities, to assess the relative ecological quality of remaining natural vegetation and semi - natural areas, and to identify opportunities and prioritize resource needs for immediate and long -term restoration and management within the conservation areas. Additional surveys and monitoring will be required in future years to gain a more complete understanding of the site's flora and fauna, the ecological functions and values of the conservation areas, and the response of vegetation to initial restoration and management treatments. Landscape scale information (e.g., surficial geology, soils, presettlement vegetation) and past land use history were researched from historic documents and other resources, and are cited within the text where appropriate. Background information regarding the site's landscape context and context within the City's planned open space and greenway system were considered and incorporated into the development of this plan as well. This plan describes natural resource restoration and management recommendations for the various natural community remnants and semi - natural areas within Foxborough's permanent conservation areas. The intent of the plan is to assist the Royal Oaks Reality, the City of Lino Lakes, and the future Foxborough's Homeowners Association in stabilizing, establishing, restoring, and managing the site's natural resources in the short term (one to five years), and to improve the ecological quality and function of the open space over the long term through an adaptive management approach. Successful restoration and management will likely require long -term collaborative efforts of various organizations and individuals, community groups, municipalities, and government agencies, including the residents of Foxborough, the City of Lino Lakes, the Rice Creek Watershed District, the Saint Paul District of the US Army Corps of Foxborough Conservation Development Restoration and Management Plan 1 • • • • • Foxborough Conservation Development Site Location and Landscape Context Legend: Proposed Greenway Corridor In Section Boundaries Exisiting Trails ProposedlConcept Trails Foxborough Conservation Development Restoration and Management Plan Figure 1 2 Engineers, and the Minnesota Department of Natural Resources. As the conservation areas are restored, managed, and enjoyed by the residents of Foxborough and visitors to the conservation areas, it is important that the residents of Foxborough and other project stakeholders be kept well informed and involved in planning and implementation of management actions, as well as the supporting science, policies, and agreements that support these management decisions. Such an approach has been demonstrated within similar private conservation developments and public preserves and open spaces to be successful in helping to foster a core group of local citizens who are well informed, more involved, and take a proprietary interest in the restoration and stewardship of the natural resources and cultural amenities within permanent conservation areas. II. Landscape Context and Site History Foxborough is a 51 -acre residential conservation development located in southeastern Lino Lakes. The legal description for the site is T31N R22W NE'/ of the NE'/ of Section 33. The conservation development is located along a regionally significant greenway and open space corridor that has been identified by the City of Lino Lakes and the Minnesota DNR (Figure 1). Geology, Soils, and Groundwater The Foxborough Conservation Development is located within the Anoka Sand Plain ecological subsection of Minnesota. The Anoka Sand Plain is a large glacial outwash plain that includes most of Anoka, Isanti, and Sherburne Counties and portions of Washington, Chisago, Ramsey, and Hennepin Counties in central Minnesota. This extensive sand plain was formed at the end of the last major ice age, circa 10,000 — 12,000 years ago, as receding of glacial ice lobes to the north formed expansive sand and gravel outwash plains along glacial river ways within central Minnesota. The soils of the Foxborough site and surrounding landscape are comprised of predominantly sandy soil types typical of the Anoka Sand Plain. Within Foxborough's conservation areas, the upland soils types are Soderville loamy fine sands with 0 to 3 percent slopes. Wetland and transitional areas are comprised of Isanti fine sandy loams, with 0 to 2 percent slopes. Soderville soils are moderately well drained, and surface runoff is negligible. Permeability of the Soderville soil type is rapid in the upper soil horizons, and moderately rapid in the lower soil profile. Soderville soils have a perched seasonal high water table at a depth of 2.0 to 3.5 feet (below the soil surface) at some time from April through June in most years. Common native vegetation of Soderville soils is White Pine (Pinus strobus), Red Pine (Pinus resinosa), and Red Oak (Quercus rubra), and Northern Pin Oak (Quercus ellipsoidalis), as well as upland prairie grasses and forbs in non - forested areas. Isanti soils are poorly to very poorly drained, with a water table at plus 1 foot to 0.5 feet below the soil surface for the very poorly drained, depressional phase, and 0.5 to 1.5 feet below the soil surface for poorly drained phase at some time October through June in most years. Native • vegetation of Isanti soils is typically comprised of Grasses (Poaceae), Sedges (Cyperaceae), Foxborough Conservation Development Restoration and Management Plan 3 • • • • Willow (Salix spp.), Quaking Aspen (Populus tremuloides), and other species adapted to persistent wet conditions (i.e. hydrophytic plant species). Figure 2 depicts a typical oblique view of the Isanti — Soderville soil complex in Anoka County, Minnesota. The complete official soils series descriptions (OSD's) for the soil types of the Foxborough site are provided in Appendix A of this report (USDA NRCS, 2005). Furthermore, additional information on soils can be obtained from the United States Department of Agriculture's Soil Survey of Anoka County, Minnesota (USDA 1977). ANOKA COUNTY, MINNESOTA Figure 2. Typical Pattern of the Isanti-Soderville-Rifle Soil Association Soil Survey of Anoka County, MN (USDA, 1977) Foxborough Conservation Development Restoration and Management Plan 4 Presettlement Vegetation (Circa 1850) According to vegetation data compiled from the Original Land Survey Notes of Minnesota (circa 1850), and mapped by F.J. Marschner (1975), the natural vegetation of the Foxborough Conservation Development and surrounding landscape at the time of European settlement was comprised predominantly of oak openings and barrens (oak savanna/woodland) in the uplands, and wet prairie within lower lying wetland areas extending north and south along the margins of the chain of lakes. The pre- settlement vegetation of Anoka County was managed by occasional to frequent wildfires during periods of drought. Occasional areas of mesic hardwood forest ( "Bog Woods ") were also in the vicinity of the Foxborough site, typically occurring in those portions of the landscape that wildfires could not penetrate (such as isolated islands and large isolated topographic depressions; Figure 3). Figure 3. Presettlement Vegetation of the Foxborough Site (Circa 1850) Foxborough Conservation Development Restoration and Management Plan 5 • III. Ecological Surveys of Foxborough's Conservation Areas From April through July 2005, CCES ecologists conducted spring and early summer surveys of the Foxborough Conservation Development site. Although the surveys were conducted throughout the entire 51 -acre development site, CCES focused the surveys on those portions of the site that will be incorporated into future conservation areas. Figure 4 illustrates the location of the conservation area outlots in relation to the overall residential site plan, and the location and alignment of the trail easement within the conservation area outlots. Existing natural community remnants, semi - natural areas, and non - native dominated landscape types were assessed for their extent and relative quality, and restoration opportunities and needs were defined, on a conceptual basis, for these areas. Based on the results of the initial 2005 surveys and review of the site plan, CCES deyeloped a concept restoration and management plan for Foxborough's permanent conservation areas. CCES ecologists identified, mapped, and surveyed several moderate to low quality natural community remnants and semi - natural vegetation types within the designated conservation areas of the Foxborough Conservation Development. The vegetation and ecological habitats of the conservation areas at the time of the 2005 surveys were comprised of oak forest remnants, aspen woodlands, lowland hardwood forest, wet meadows, mixed emergent marshes, and non - native upland old fields and pastures. The location and extent of these natural community remnants and semi - natural areas are depicted in Figure 5, and descriptions of these areas are provided in the text below. Major Vegetation Types Oak Forest The northeast corner of the Foxborough site contains an oak forest remnant that grades between mesic and dry oak forest. The oak forest is of moderate quality, with am intact canopy comprised predominantly of Red Oak (Quercus rubra), Northern Pin Oak (Quercus ellipsoidalis), White Oak (Quercus alba), Bur Oak (Quercus macrocarpa), and Black Cherry (Prunus serotina), and occasional Quaking Aspen (Populus tremuloides) Red Maple (Acer rubrum), and Hackberry (Celtis occidentalis). Furthermore, this oak forest has small inclusions of lowland hardwood forest within poorly drained areas and low -lying areas of the forest, with the canopy comprised mostly of Red Maple, Hackberry, Green Ash (Fraxinus pensylvanica), Paper Birch (Betula papyrifera) and Box Elder (Acer negundo). Portions of the oak forest are of moderate ecological quality, with a relatively species -rich native shrub layer and herbaceous layer. Such intact forest areas will require fewer initial restoration resources than degraded forest remnants, but all forests on the site will require restoration, monitoring, and management through time. Other areas of the oak forest of the Foxborough site have been more severely degraded by past land use practices (such as grazing), and will require considerable initial restoration resources and management in the short term to return these, areas to natural communities that are comprised of representative tree, shrub, and herbaceous species. Problematic invasive species that require removal, treatment, and management within Foxborough's oak forest remnants include: Common Buckthorn (Rhamnus cathartica), Reed Canary Grass (Phalaris arundinacea; along forest/wetland edges and into adjacent uplands), Foxborough Conservation Development Restoration and Management Plan 6 P0x130ROUGH -57: 889.52.21-E - 450.00 . i at•-■-•,--,"" *1 1 33l 1 \ . 24 , . . 1 - -11 / ,24. 1 , ....-- - .\ 4,-4 b itd ir . . is..... w....• S.A.

Oak Woodlands /Savannas Portions of the site contain small, fragmented oak woodland remnants and overgrown oak savanna remnants of low to moderate quality. These small woodland and savanna remnants are commonly associated with the oak forest and aspen woodlands of the Foxborough site. Fortunately, within these remnants, the oak canopy structure remains intact, and initial restoration efforts should focus on the re- establishment of representative shrub and herbaceous layers, selective thinning of the oak canopy and removal of damaged or diseased canopy limbs, prescribed burning, and the removal and management of invasive species such as Smooth Brome, Reed Canary Grass, Common Buckthorn, and Prickly Ash. Some woodland and savanna areas contain small depressional wetland areas that will also benefit from prescribed burning and invasive species management, and additional management strategies commonly associated with oak woodland and savanna management and restoration. Wet Meadows (and Associated Shallow Marsh Fringes) The many wetlands that occur within Foxborough's conservation areas are relatively degraded due to past land use practices (such as grazing, drainage, nutrient loading, and vegetation manipulation) and the establishment of aggressive invasive species. Foxborough's remaining wetland plant communities will require considerable restoration and long -term management to re- establish and maintain higher quality natural vegetation and representative hydrology over time. Reed Canary Grass (Phalaris arundinacea) is an invasive wetland grass, and is the primary problematic invasive species within all of the wetlands (and adjacent upland transitions) of the Foxborough site. Reed Canary Grass monotypes (aggressive, single species stands) within isolated wetlands are more likely to be eradicated and managed, than reed canary grass stands within the larger interconnected waterways and wetlands along the eastern and southern boundary of the site and at the northeast corner of the site. It will be very difficult (and expensive) to control the re- invasion of Reed Canary Grass from adjacent, hydrologically connected wetlands and regional waterways, since reed canary grass seed is commonly dispersed via floodwater and migrating waterfowl. For these reasons, short-term priorities should be focused on restoring and managing the smaller, hydrologically isolated wetlands within Foxborough's conservation areas. To be successful and cost effective, longer -term restoration efforts within the outermost regional waterways that define portions of the north, east, and southern boundaries of the site should be addressed on a collaborative basis with adjacent landowners and future restoration efforts on adjacent lands. Although Purple Loosestrife (Lythrum salicaria) and Common Reed (Phragmites australis) were not detected within the wetlands of the Foxborough property during the initial 2005 surveys, these aggressive invasive species may be present within adjacent wetlands. Both species should be surveyed for during future monitoring, and should be managed with biological controls and herbicide if detected within Foxborough's conservation areas. The northern end of the westernmost wetland on the site also supports a dense stand of Narrow- Leaved Cattail (Typha Foxborough Conservation Development Restoration and Management Plan 9 • angustifolia) and Broad - Leaved Cattail (Typha latifolia) within the lowest and wettest topographic areas of the wetland basin. Cattails are often a problematic wetland species within degraded wetlands of central Minnesota, and should be aggressively managed as to favor conditions favorable to the establishment of more diverse native wetland plant communities. Narrow- Leaved Cattail (Typha angustifolia) is a non - native, invasive plant that hybridizes with the native Broad - Leaved Cattail (T. latifolia) to produce the invasive Typha x glauca. Cattails can be managed by manual removal and herbicide treatments. Most of the wetlands on the Foxborough site support at least a minimal native species component. Lake Sedge (Carex lacustris), Porcupine Sedge (Carex comosa), and Tussock Sedge (Carex stricta) were commonly observed within Foxborough's wetlands. However, Reed Canary Grass is so prevalent throughout all wetlands, that these representative native sedge species have been reduced in cover and number, and considerable resources and effort will be required to restore native sedge meadows to the site over the next five to ten years. Two noteworthy wetland areas were encountered within the proposed conservation area during the early spring (2005) survey, which represent unique opportunities for restoration of uncommon wetland plant assemblages within the Foxborough conservation areas. A small groundwater seepage area was documented within the oak forest/woodland remnant of the northeast corner of the site. This area of groundwater discharge contains a small Tussock Sedge (Carex stricta) meadow. In the southwest corner of the site, a small and overgrown wet meadow /wet prairie remnant was encountered. If cleared of brush (Buckthorn, Willow, Aspen, and Dogwood) and properly managed to favor diverse native herbaceous vegetation (with prescribed burning or other methods), this area may support rare species and/or diverse remnant wet prairie vegetation associated with similar restored areas within Lino Lakes and adjacent communities. Aspen Woodlands Most of the wetlands on the site are encompassed by relatively dense, immature stands of Quaking Aspen (Populus tremuloides) along the wetland/upland transitional zones. As is the case with the Foxborough site, aspen stands frequently establish along wetland fringes on the Anoka Sand Plain in the absence of fire, and form dense, shaded, species -poor stands. In the absence of past management, these aspen stands of the Foxborough site are further degraded by Reed Canary Grass (Phalaris arundinacea), Common Buckthorn (Rhamnus cathartica), Glossy Buckthorn ( Rhamnus frangula), and other noxious or aggressive weed species. The aspen woodland fringes of the Foxborough site are comprised (most often) of single- species canopies of 2 to 12 inch diameter aspen, with Reed Canary Grass, Sensitive Fern (Onoclea sensibilis), and Pennsylvania Sedge (Carex pensylvanica) common to the ground layer. CCES recommends that at least some of these Aspen dominated wetland fringes be selectively thinned or completely cleared of Quaking Aspen, as to promote the re- establishment and management of more diverse herbaceous communities, such as mesic /wet prairie, and wet meadow natural communities. However, CCES recognizes that some of the aspen stands should remain intact, as these young woodland stands do provide limited ecological functions and aesthetic values, and serve as useful visual screens of adjacent residential structures and industrial land uses. Foxborough Conservation Development Restoration and Management Plan 10 Degraded Hardwood Forest A 1.5 acre degraded hardwood forest occurs within the far northwest corner of the site. This forest remnant canopy is comprised of American Elm (Ulmus americana), Box Elder (Acer negundo), Black Cherry (Prunus serotina), Green Ash (Fraxinus americana), and Hackberry (Celtis occidentalis), with occasional large Northern Pin Oak (Quercus ellipsoidalis) and Red Oak (Quercus rubra) trees intermixed. Common Buckthorn (Rhamnus cathartica), an invasive exotic understory species, is dominant throughout the understory and shrub layer of this forest remnant, as understory trees (up to 12" in diameter), large shrubs, saplings, and seedlings. Due to the presence of the dense buckthorn stand and past soil disturbance and compaction, the herbaceous layer is highly degraded (and absent in places). Forest soil development is poor, and forest leaf little is sparse to absent. Buckthorn removal and management is an immediate need within this forest remnant, and will require several years of follow -up restoration and management to begin re- establishing a native shrub and herbaceous layer. Upland Old Fields and Pastures Portions of the proposed conservation areas are currently non -native dominated old field and pastures dominated by Smooth Brome and Kentucky Bluegrass, and other introduced pasture grasses. The old fields typically occur on sandy, well- drained soils on pronounced knolls, but also transition into more poorly drained areas at toe slopes and along wetland edges. Within lower -lying areas, the old fields are dominated by Reed Canary Grass and Sensitive Fern, with occasional Aspen, Willow, and Raspberry. Old fields should be restored to dry prairie in the driest of areas, and transition to mesic and wet prairie at the base of slopes and along wetland edges. Furthermore, restored prairies of Foxborough's conservation areas will likely grade into restored oak savannas and oak woodlands, as well as managed aspen woodlands. Compensatory Wetland Mitigation Area (SE Corner of Site): The compensatory wetland mitigation area 1.99 -acre (87,097 square feet) in size is planned for construction within a degraded upland old -field over sandy, well - drained soils. Vegetation of the old field in May 2005 was predominantly invasive non- native grasses, such as Smooth Brome (Bromus inermis) and Kentucky Bluegrass (Poa pratensis), with Pennsylvania Sedge (Carex pensylvanica), Sun - Loving Sedge (Carex heliophila), and Canada Goldenrod (Solidago canadensis). In accordance with the site plan and wetland mitigation plan, this old field will be excavated to a depth below the normal water table elevation to facilitate the establishment of an on site compensatory wetland mitigation area. Although the original wetland mitigation plan calls for establishment of wetland vegetation within a saturated (to inundated) sterile sandy subsoil condition, CCES recommends excavating the mitigation wetland 2 to 4 inches deeper, and back filling to designed elevations with a weed -free native organic wetland soil that would be donated from wetland areas to be filled elsewhere on the site. A native organic wetland soil medium will better facilitate the establishment of high quality native wetland seed mixes (and plant material) to be prescribed for and installed within this wetland mitigation area. To achieve 2 inches of organic material across 2 acres of wetland mitigation area will require 14,520 cubic feet (or 537 cubic yards) of native wetland soils donated from impacted wetland areas elsewhere on the site. Foxborough Conservation Development Restoration and Management Plan 11 In accordance with the approved residential site plan, 0.69 acres (25,267 square feet) of existing wetland within the northwest corner of the site will be excavated and filled with sandy subsoil to facilitate grading for residential lots. As previously estimated, CCES estimates that 537 cubic yards of organic wetland soil could be excavated and stockpiled from this wetland soil `donor' site and spread within the planned 1.99 acre wetland mitigation area at a depth of 2 inches, to better facilitate the successful establishment of a diverse wetland plant community within the wetland mitigation area. Furthermore, CCES recommends that the surface wetland soils containing weed species (such as Reed Canary Grass) should be removed and discarded prior to the excavation of suitable organic wetland subsoils that are free of weed species. In order to achieve the planned final grade and spot elevations of the mitigation wetland, the sandy subsurface soils of the wetland mitigation area will need to be graded below final grade to accommodate the spreading of the native organic wetland soils donated from other areas of the site. Final grade and spot elevations of the wetland mitigation area will be met with the re- distribution of the native organic wetland soil during final grading and prior to seeding. Wildlife Observations During the spring and summer surveys of the Foxborough site, CCES ecologists observed five species of mammals, six amphibian species, three reptile species, and eighteen bird species. Table 1 provides a summary of all animal species observed within, or adjacent to, the Foxborough property while conducting the 2005 surveys. Additional focused faunal surveys in future years will likely result in additional wildlife species observations. Rare Plants and Animals Two animal species observed during the ecological surveys of Foxborough are listed as Special Concern in Minnesota by the Minnesota Department of Natural Resources (Snapping Turtle and American White Pelican). Special Concern species are not protected under Minnesota's endangered and threatened species legislation (Minnesota Statutes 84.0895). Furthermore, the observation of numerous American White Pelicans was a high - altitude migratory fly -over, and was not directly associated with the natural areas of the Foxborough property. No state - listed vascular plant species were documented within the Foxborough site during the 2005 surveys. However, several rare plant populations have been recently documented by CCES ecologists and Marty Asleson (City of Lino Lakes) within close proximity to the Foxborough property. Such species include: Tubercled Rein Orchid (Platanthera flava var. herbiola; State Endangered), Lance - Leaved Violet (Viola lanceolata; State Threatened), and Clinton's Bulrush (Scirpus clintonii; State Special Concern). Marginal suitable habitat exists within Foxborough's conservation areas for all three of these species. Moreover, future restoration and management of natural vegetation may result in the voluntary re- establishment of these and other associated rare species within Foxborough's conservation areas. Future monitoring of restored and managed natural areas should include rare plant surveys for rare plant species of the Anoka Sand Plain.

Foxborough Conservation Development Restoration and Management Plan 13 • IV. Restoration and Management Needs and Recommendations Foxborough Restoration and Management Goals • Restore, manage, and improve pre- existing moderate and low quality natural communities and natural resources within Foxborough's conservation areas; • Re- establish and/or restore native vegetation cover within highly disturbed and non- native landscape areas within the conservation areas that is ecologically appropriate and suited to the environmental conditions of the site and is suitable to proposed human uses and desired site aesthetics; • Establish trails and conservation signage (and other infrastructure) that help facilitate sustainable natural resource management and other programmed activities. Trails should offer access and provide opportunities for passive recreational opportunities, such as walking, jogging, cross - country skiing, wildlife observation, and nature interpretation; • Provide recreational and educational opportunities for the residents of Foxborough and trail users that are compatible with sustaining, restoring, and improving the natural vegetation and ecological functions of Foxborough's conservation areas; • Implement surface water and public infrastructure planning and development within the site and adjacent landscape that compliments (and does not further degrade) the natural resources of the site; • Identify and capitalize on opportunities to connect Foxborough's restored natural areas with adjacent natural areas, either through reestablishing and improving ecological/habitat connections and pedestrian/recreational connections, or through developing educational programs, volunteer opportunities, and collaborative relationships with adjacent landowners, future conservation developments, and/or local and state government agencies. Prescribed Native Plant Communities Much of the existing vegetation of Foxborough's conservation areas is currently in a moderate to low quality natural condition or degraded semi- natural condition. All natural areas within the designated conservation areas will require considerable resources to restore and/or manage vegetation as natural plant communities well into the future. Furthermore, areas of very disturbed semi - natural vegetation and non - native cover (i.e. degraded wet meadows, old- fields, and buckthorn - infested woodlands and forests), will require restoration tasks such as invasive and exotic vegetation removal, chemical and manual treatments and/or biological controls of noxious weed species, and replanting /reseeding with native plant community cover. To minimize the resources require for restoring and managing native Vegetation within Foxborough's conservation areas, pre - existing natural communities will not be converted to other natural community types. Figure 6 illustrates the location and extent of prescribed natural and semi - natural vegetation types within Foxborough's conservation areas. Rather, existing natural communities will be managed, improved, and augmented with appropriate native species seed mixes and plantings when necessary. Non - native landscape types, such as old- fields and Foxborough Conservation Development Restoration and Management Plan 14 Foxborough Conservation Development Conservation Area Restoration and Management Plan Legend: OF LHF OS AW Oak Forest Lowland Hardwood Forest Oak Savanna Aspen Woodland DP WP WM Dry Prairie Wet Prairie Wet Meadow Mixed Emergent Marsh Wetland 11IUgallon 11 Stormwater Wetland Wetland Mitiagtion Area Property Boundary Figure 6 Foxborough Conservation Development Restoration and Management Plan 15 Reed Canary Grass dominated wetland edges, should be actively and aggressively converted and restored to a more diverse native vegetation type. The following are detailed descriptions of natural community types that have been prescribed for Foxborough's conservation areas, as depicted in Figure 6. Oak Forest Oak Forest is an upland deciduous forest with >30% oaks, and is common and widespread throughout much of Minnesota. It is most common on dry to dry-mesic sites in the deciduous forest - woodland zone but also occurs occasionally in the southern and western parts of the conifer - hardwood zone, and in stream valleys in the prairie zone. At least 30% of the tree canopy in an Oak Forest is made up of oak trees. Most often aspen, paper birch, or black cherry trees make up the remainder of the canopy. The actual composition of the community, however, varies considerably in response to variation in soil moisture, soil type, fire history, and climate. The driest stands of Oak Forest are dominated by northern pin oaks and white oaks, with black oaks, shagbark hickories, and sometimes bur oaks important in southeastern Minnesota. These stands occur on nutrient -poor, well - drained sandy soils on outwash plains, river terraces, and beach ridges. They have relatively open canopies, with between 70% and 80% cover. The canopy height is usually between 13 and 17 meters. Because of the open canopy, the shrub layer is often very dense. American hazel dominates the shrub layer, which also often contains gray -bark dogwood, blueberries, and blackberries. Some of the more common ground layer species are the sedge (Carex pensylvanica), wild geranium (Geranium maculatum), Virginia creeper (Parthenocissus inserta), wild sarsaparilla (Aralia nudicaulis), and hog -peanut (Amphicarpaea bracteata). Commonly, at least some of the oak trees in the dry stands have multiple stems and thick, spreading lower branches, indicating that these trees grew up in a disturbed and more open setting. Minnesota public land survey records indicate, in fact, that many of these dry stands were oak savanna or oak woodland before European settlement and with fire suppression have succeeded to forest. Oak regeneration is rare in these stands now, as the oak species reproduce poorly under forest canopies. In the absence of fire, relatively mesic or fire - sensitive species such as bitternut hickory, basswood, and red maple, are increasing in abundance in the community. Northern red oaks, white oaks, or bur oaks dominate the more mesic stands of Oak Forest. These stands occur on sites that had fewer severe fires before European settlement than the sites on which dry Mixed Oak Forest occurs. These mesic stands most likely were always forest, rather than woodland or savanna. They have tall (> 20 meters), straight, single - stemmed trees that lack spreading lower branches. Commonly, mesic fire - sensitive tree species are present with the oaks in these stands, especially in the understory. These species include basswood, green ash, bitternut hickory, big- toothed aspen, and butternut. The shrub layer in mesic stands is sparser than in dry stands and, correspondingly, the forb layer is denser and more diverse and there are more graminoid species. Like the drier stands, however, there is little oak regeneration, and most mesic Oak Forests appear to be succeeding to Maple- Basswood forest. Heavy selective logging of the oaks in mesic stands may accelerate this Foxborough Conservation Development Restoration and Management Plan 16 • trend, producing young stands of Maple- Basswood Forest. The mesic stands often grade into drier stands of Maple- Basswood Forest, but differ from them by having a somewhat denser shrub layer and the herbs woodrush (Luzula acuminata) and pointed - leaved tick- trefoil (Desmodium glutinosum) in their understory. In general, most existing stands of Oak Forest have been disturbed by grazing or selective cutting, or have been fragmented by development. Natural stands of mesic Mixed Oak Forest are rare. Drier stands are more common, in part because relative to the mesic forests they occur on sites with soils less suitable for cultivation. Additionally, dry Oak Forests may have increased in extent somewhat following fire suppression, succeeding from oak savanna and woodland. Disturbed stands of oak forest commonly have dense subcanopies of prickly ash, or of the exotic species common buckthorn and Tartarian honeysuckle, which have also now invaded many undisturbed stands. Disturbance through grazing may also be partly responsible for the lack of regeneration in Oak Forests, especially in stands with heavy soils that compact readily with trampling. A comprehensive plant species list for Foxborough's Oak Forest restoration area is provided in Appendix B of this report. Lowland Hardwood Forest Lowland Hardwood Forest is a wet -mesic forest that is present throughout Minnesota. It is transitional between the terrestrial and palustrine systems, occurring on sites with seasonally high water tables (within the tree - rooting zone) but that do not flood regularly and that have mineral rather than peat soils. In accord with the poorly drained sites on which the Lowland Hardwood Forests occur, species tolerant of periodic soil saturation dominate the tree canopy. American elms and black ashes are common canopy dominants, but most stands are mixed, with slippery elms, rock elms, basswoods, bur oaks, hackberries, yellow birches, green ashes, black ashes, quaking aspens, balsam poplars, and paper birches as important species. The tall-shrub layer is usually discontinuous and is composed of a mixture of upland and lowland shrubs. The ground layer is composed mostly of upland herbs that do not root to the water - table. Lowland Hardwood Forest usually occurs in fire - protected areas, although even in unprotected areas the community burns infrequently because the woody vegetation is usually hydrated, especially in the spring. Lowland Hardwood Forest soils differ from Hardwood Swamp Forest soils by being mineral rather than peaty and from the mineral soils of other mesic upland forest types by being seasonally saturated (at depths greater than 0.5 meters). Lowland Hardwood Forest is often composed of late - successional species, but few stands in Minnesota have old canopy trees, presumably because of windthrow and infrequent episodes of killing floods. Lowland Hardwood Forest is topographically transitional between upland forests and forested peatlands and is best developed on flat terrain where such transition zones are broad (e.g., on river terraces above normal flood levels, on loamy ground moraine, and on drumlin fields). Currently, there are no recognized subtypes or sections of Lowland Hardwood Forest. Following further field review, stands of Lowland Hardwood Forest may be reclassified as wet subtypes of Aspen -Birch or Aspen Forest, or dry subtypes of Hardwood Swamp Forest. A comprehensive Foxborough Conservation Development Restoration and Management Plan 17 plant species list for Foxborough's Lowland Hardwood Forest restoration area is provided in Appendix B of this report. Aspen Woodlands Aspen woodlands are typically mesic upland vegetation with 10 -70% tree cover, of which <25% is by conifers, with aspens comprising >70% of tree cover and herbaceous species comprising <30% of non -tree cover. Aspen woodlands occur primarily in the deciduous forest - woodland zone, with scattered groves in the prairie zone. Quaking aspen is the dominant canopy species in the community across most of its range. In north - central Minnesota, however, big - toothed aspens occasionally dominate the canopy, and in the northwest, balsam poplars sometimes dominate low, moist areas. Bur oaks and green ashes are common associates throughout the community's range. Stands of Aspen Woodland have either dense canopies of even -aged immature trees, irregular canopies of young and old trees, or tall, even canopies of mature trees. The woody understory in the community is well - developed, with 40 -90% cover. The understory may contain plants, including tree species, of several different height classes or it may have a well - defined shrub layer. On drier sites, hazelnut, gray -bark dogwood, chokecherry, downy arrow -wood, Rosa spp., and Rubus spp. are common understory shrubs. On wetter sites, the common understory shrubs are red -osier dogwood, gray -bark dogwood, pussy willow, Bebb's willow, bog birch, and meadow sweet. These species are particularly characteristic in Aspen Woodlands in northwestern Minnesota that originated following the invasion of areas of wet - mesic Upland Prairie or Wet Meadow by aspen. Aspen Woodland is a short-lived, early successional community intermediate between Upland Prairie (including Brush - Prairie) and Aspen or Oak Forests. Before European settlement, the distribution of Aspen Woodland in the prairie zone was determined by fire, with the community occurring in areas where fires were less frequent and intense than in open prairie areas. In the deciduous forest - woodland zone, Aspen Woodland probably was maintained by fire and occurred in association with Oak Forest, Aspen Forest, and some pine forests. Aspen Woodland has become more abundant in Minnesota because of fire suppression and perhaps wetland draining. Communities that originate following logging in the deciduous forest - woodland and conifer - hardwood forest zones often resemble Aspen Woodland but are not considered true Aspen Woodlands in this classification. When Aspen Woodland occurs with other related community types, such as Brush - Prairie and Aspen Openings, it tends to occur as narrow ecotonal bands between the other types or as small inclusions, and may be ignored in mapping. A comprehensive plant species list for Foxborough's Aspen Woodland restoration areas is provided in Appendix B of this report. Oak Savanna Oak savannas are upland plant communities with 10 -70% cover by trees (of which <25% is conifer), where >30% of non -tree cover is herbaceous (prairie - dominated) and where oaks comprise >30% of the tree cover. The soil is composed of sand or gravel (sometimes with a thin organic surface layer), or any texture on steep slopes. This dry to dry-mesic community is most common in the deciduous forest - woodland zone, but also occurs sporadically throughout the prairie zone. The principal trees are bur oaks and northern pin oaks, but black oaks are also Foxborough Conservation Development Restoration and Management Plan 18 • • • • common in the southeast. Northwards, quaking aspens become more frequent in the community. The stature and spacing of trees is somewhat variable, reflecting differences in soils, topography, and climate, factors that strongly affect local droughtiness and fire frequency. Small, gnarly, open -grown trees are most common, although in moister spots, or in heavier soils, larger trees are sometimes more common. Tree spacing ranges from sparsely and evenly distributed to strongly clumped in moderately dense patches. Shrub cover is variable as well. The species composition of the shrub layer depends somewhat upon soil characteristics. Oak grubs and chokecherries are common on all soil types. On sandier soils, prairie willows (Salix humilis), New Jersey tea (Ceanothus americanus), American hazelnuts (Corylus americana), sand cherries (Prunus pumila), and juneberries (Amelanchier spp.) are usually present. Wolfberries (Symphoricarpos occidentalis) are commoner on heavier soils. Dry Oak Savanna occurs on the same kinds of landforms as Dry Prairie, except for bedrock bluffs. Correspondingly, substrates range from excessively - drained to well - drained, sand to loam soils. The presence of savanna rather than prairie indicates a lower fire frequency or intensity (or both) than in prairie. Dry Oak Savanna requires less frequent fire than Mesic Savanna for maintenance. However, in the complete absence of fire woodland will eventually replace Dry Oak Savanna. Grazing and browsing animals may also have had a role in the maintenance of Dry Oak Savanna. Because Dry Oak Savanna occurs on sites that are not as suitable for cultivation as Mesic Savanna sites, and because succession in the absence of fire is not as rapid, more examples remain of Dry Oak Savanna than of Mesic Oak Savanna. A comprehensive plant species list for Foxborough's Oak Savanna restoration areas is provided in Appendix B of this report. Mesic Prairie Mesic Prairies are upland grassland dominated by prairie species, with <10% tree cover and <50% shrub cover ( <30% in far northwestern Minnesota), and NOT growing on steep slopes or on sand- or gravel - dominated soil. Mesic Prairie is a type of Upland Prairie, which occurs primarily in the prairie zone, with scattered occurrences in the deciduous forest - woodland zone. Mesic Prairies are dominated by grasses. The tall grasses, big bluestem (Andropogon gerardii) and Indiangrass (Sorghastrum nutans), are the major dominants on moist sites. Prairie dropseed (Sporobolus heterolepis) is common on both dry and moist sites. Forbs typically are abundant (but subdominant to the grasses) and may have high local diversity. Forb species composition varies with site moisture, although some forb species occur on almost all sites, moist or dry. Several low shrub or sub -shrub species are common on Upland Prairie; the most characteristic is leadplant (Amorpha canescens). Taller brush and trees are absent or scattered, however brush or woodland areas may be interspersed with prairie, usually in association with topographic and aquatic features that provide protection from fire. The most important cause of variation in species composition in prairie communities is variation in soil moisture. The local soil moisture regime is determined by slope, aspect, proximity to the water table, and soil texture. On a regional scale, variation in species composition is primarily caused by climatic variation (i.e., the westward decline in precipitation and northward decline in temperature in Minnesota). Foxborough Conservation Development Restoration and Management Plan 19 Upland Prairies occur on a range of landforms in the prairie zone, from nearly flat glacial lakeplains to steep morainic slopes. In the deciduous forest - woodland zone, prairies occur on droughty, level outwash areas and steep south - and west - facing slopes. The pre - European settlement distribution of prairie was related to the interaction of local fire frequency with growth rates of woody species: where conditions were favorable for rapid growth, more frequent fires were necessary to maintain prairie over savanna, woodland, or forest. Fragmentation of Upland Prairie since European settlement has reduced fire frequency throughout the prairie and deciduous forest - woodland zones, and most prairie remnants have more brush and trees than were present in the past. Mesic Prairie is a dry-mesic to wet -mesic grassland that occurs mainly in the prairie zone in southern and western Minnesota and sporadically in the deciduous forest - woodland zone. Mesic Prairie is dominated by grasses. Big bluestem (Andropogon gerardii), Indiangrass (Sorghastrum nutans), and prairie dropseed (Sporobolus heterolepis) are the major native species on most sites, with little bluestem (Schizachyrium scoparium) and porcupine grass (Stipa spartea) important on drier sites, and switchgrass (Panicum virgatum) and prairie cordgrass (Spartina pectinata) common on wetter sites. The introduced grass Kentucky bluegrass (Poa pratensis) is present at most sites; its is a function of the site's disturbance history. Forbs are abundant (but usually subdominant to grasses) and have high local diversity. Forb species - composition also varies locally with soil moisture. There is greater regional variation among forbs than among grasses. Common forb species include purple prairie- clover (Petalostemon purpureum), white prairie- clover (P. candidum), ground -plum (Astragalus crassicarpus), prairie - turnip (Psoralea esculenta), rough blazing -star (Liatris aspera), Canada goldenrod (Solidago canadensis), stiff goldenrod (S. rigida), Missouri goldenrod (S. missouriensis), prairie thistle (Cirsium flodmani), smooth aster (Aster laevis), stiff sunflower (Helianthus rigidus), Maximilian sunflower (H. maximiliani), smooth rattlesnake -root (Prenanthes racemosa), white sage (Artemisia ludoviciana), wood lily (Lilium philadelphicum), white camas (Zigadenus elegans), heart- leaved alexanders (Zizia aptera), prairie larkspur (Delphinium virescens), downy phlox (Phlox pilosa), hoary puccoon (Lithospermum canescens), tall cinquefoil (Potentilla arguta), alum -root (Heuchera richardsonii), wood - betony (Pedicularis canadensis), northern bedstraw (Galium boreale), prairie bird -foot violet (Viola pedatifida), oval - leaved milkweed (Asclepias ovalifolia), and showy milkweed (A. speciosa). Purple coneflower (Echinacea angustzfolia) is common on drier sites in the western part of the community's range. Leadplant, prairie rose, sand cherry, wolfberry, and prairie willow are common low -shrub or sub -shrub species. Fragrant false indigo is common on moister sites. Trees and taller brush often occur along the margins of wetlands adjacent to Mesic Prairies. Mesic Prairie is a fire- dependent community. In the absence of fire, occurrences of Mesic Prairie are invaded by brush and trees. In the prairie zone, Mesic Prairie occurs on nearly level glaciolacustrine and glaciofluvial deposits, and on flat or gently rolling morainic landforms. In southeastern and, to a lesser extent, southwestern Minnesota, the glacial deposits are overlain by loess. Bedrock subtypes of Mesic Prairie exist in a few areas where bedrock is within about one- and- one - quarter meters of the ground surface and there are numerous small patches of exposed rock. Within the deciduous forest - woodland zone, Mesic Prairie usually occurs on level outwash areas or on broad, sandy river terraces. Foxborough Conservation Development Restoration and Management Plan 20 • • • The soils in Mesic Prairie are predominantly mollisols with thick, dark mineral surface layers that have high base saturation and dominantly bivalent cations. They range in texture and drainage from silty and somewhat poorly drained to sandy and somewhat excessively drained, with moderately well - drained to well - drained, loamy soils being most common. Mesic Prairie grades into Wet Prairie on moister sites and into the Hill and Sand- Gravel subtypes of Dry Prairie on drier sites. Separation of Mesic Prairie from other prairie types is based primarily on landform or substrate characteristics rather than on species composition, as floristic boundaries between Mesic Prairie and other prairie types are not well defined. A comprehensive plant species list for Foxborough's Mesic Prairie restoration areas is provided in Appendix B of this report. Dry Prairie Dry Prairies are upland grasslands dominated by prairie species, with <10% tree cover and <50% shrub cover, where the substrate is composed of sand or gravel (sometimes with a thin organic surface layer), or any texture on steep slopes. (Some examples may occur on sandy soils in temporarily flooded areas). Dry Prairie is a type of Upland Prairie, which occurs primarily in the prairie zone, with scattered occurrences in the deciduous forest - woodland zone. These communities are dominated by grasses. The tall grasses, big bluestem (Andropogon gerardii) and Indiangrass (Sorghastrum nutans), are the major dominants on moist sites. Prairie dropseed (Sporobolus heterolepis) is common on both dry and moist sites. Forbs typically are abundant (but subdominant to the grasses) and may have high local diversity. Forb species composition varies with site moisture, although some forb species occur on almost all sites, moist or dry. Several low shrub or sub -shrub species are common on Upland Prairie; the most characteristic is leadplant (Amorpha canescens). Taller brush and trees are absent or scattered, however brush or woodland areas may be interspersed with prairie, usually in association with topographic and aquatic features that provide protection from fire. The most important cause of variation in species composition in prairie communities is variation in soil moisture. The local soil moisture regime is determined by slope, aspect, proximity to the water table, and soil texture. On a regional scale, variation in species composition is primarily caused by climatic variation (i.e., the westward decline in precipitation and northward decline in temperature in Minnesota). Upland Prairies occur on a range of landforms in the prairie zone, from nearly flat glacial lakeplains to steep morainic slopes. In the deciduous forest - woodland zone, prairies occur on droughty, level outwash areas and steep south - and west - facing slopes. The pre - European settlement distribution of prairie was related to the interaction of local fire frequency with growth rates of woody species: where conditions were favorable for rapid growth, more frequent fires were necessary to maintain prairie over savanna, woodland, or forest. Fragmentation of Upland Prairie since European settlement has reduced fire frequency throughout the prairie and deciduous forest - woodland zones, and most prairie remnants have more brush and trees than were present in the past. Dry Prairie is a dry to dry-mesic herbaceous community dominated by grasses and sedges. It occurs throughout the prairie zone and sporadically in the deciduous forest - woodland zone. Dry Prairie has considerable variation in species composition, reflecting interactions among Foxborough Conservation Development Restoration and Management Plan 21 geography (namely climate), soils, and topography. In general, Dry Prairies have a greater component of Great Plains species than Mesic Prairies, especially in prairies in the western part of Minnesota. Big bluestem (Andropogon gerardii) is always present in the community and usually important, but it does not achieve the dominance it typically has in Mesic Prairie. Indiangrass (Sorghastrum nutans) is more limited in occurrence, generally appearing only where conditions approach mesic. Mid - height and short grasses and sedges are usually dominant in Dry Prairie. Among the more common are porcupine grass (Stipa spartea), little bluestem (Schizachyrium scoparium), side -oats grama (Bouteloua curtipendula), prairie June -grass (Koeleria macrantha), and sun - loving sedge (Carex heliophila). Forb variation within the community is more pronounced. Some widespread, characteristic species are dotted blazing star (Liatris punctata), pasque flower (Pulsatilla nuttalliana), prairie golden -aster (Heterotheca villosa), stiff sunflower (Helianthus rigidus), silky aster (Aster sericeus), green milkweed (Asclepias viridiflora), stiff goldenrod (Solidago rigida), gray goldenrod (Solidago nemoralis), Missouri goldenrod (Solidago missouriensis), and narrow- leaved puccoon (Lithospermum incisum). Dry Prairies share many forb species with Mesic Prairies, including rough blazing star ( Liatris aspera), buffalo -bean (Astragalus crassicarpus), tooth- leaved evening primrose (Calylophus serrulatus), silverleaf scurfpea (Psoralea argophylla), thimbleweed (Anemone cylindrica), Louisiana sagewort (Artemisia ludoviciana), prairie larkspur (Delphinium virescens), heart- leaved alexanders (Zizia aptera), purple prairie - clover (Petalostemon purpureum), hoary puccoon (Lithospermum canescens), prairie smoke (Geum triflorum), and wood lily (Lilium philadelphicum). Three sub- shrubs— leadplant (Amorpha canescens), prairie rose (Rosa arkansana), and wolfberry (Symphoricarpos occidentalis) -- typical in Mesic Prairies are also generally present in Dry Prairie. Soil- encrusting lichens and the fem -ally rock- spikemoss (Selaginella rupestris) are often common in Dry Prairie. Brush, and sometimes trees, may be present in hollows and draws. Bur oak (Quercus macrocarpa), chokecherry (Prunus virginiana), wild plum (Prunus americana), and smooth sumac (Rhus glabra) are the most widespread woody species. Other woody species more limited in distribution in the community are northern pin oak (Quercus ellipsoidalis), black oak (Quercus velutina), and hazel (Corylus americana). Dry Prairies are maintained by fire but require less frequent fires than mesic and wet prairies because the droughty conditions within Dry Prairies slow or prevent the growth of woody species. Dry Prairie occurs on a variety of landforms, including sand dune blankets of mid - Holocene origin, glacial lake beach ridges, outwash deposits, ice - contact features (kames, eskers), morainic hills, erosional slopes in glacial drift, and bedrock -cored bluffs. Soils range from nearly pure sand with little profile development, to mollisols, although the latter have a much thinner organic -rich surface horizon than the soils of Mesic Prairie. All overlie deep glacial drift except for those of the bedrock -cored bluffs, which are formed in a thin layer of loess or residuum. Soils are well drained to excessively drained. Depending upon the degree of slope, the slope aspect, and the soil composition, Dry Prairie intergrades with Mesic Prairie. A comprehensive plant species list for Foxborough's Dry Prairie restoration areas is provided in Appendix B of this report. Foxborough Conservation Development Restoration and Management Plan 22 • • Wet Prairie Wet prairies are prairie- species dominated grassland communities growing on saturated and temporarily flooded soils with <30% tree cover and <50% shrub cover ( <30% in northwestern Minnesota). Wet prairie occurs mainly in the southern and western parts of Minnesota's prairie ecoregion, with scattered occurrences in the deciduous forest - woodland ecoregion. Typically, grasses dominate wet prairies, but sedges are also important in the community. The major cover - forming grasses in wet prairies in eastern Minnesota are prairie cordgrass (Spartina pectinata) and blue joint (Calamagrostis canadensis). Prairie cordgrass and blue joint are also present in Wet Prairies in western Minnesota, but the major cover - forming grasses in the west are bog reed - grass (Calamagrostis inexpansa), big bluestem (Andropogon gerardii), and the low grass, mat muhly (Muhlenbergia richardsonis). Other common grasses in the community are switchgrass (Panicum virgatum), wheatgrass (Agropyron trachycaulum), fowl meadow grass (Poa palustris), and sweet grass (Hierochloe odorata). The introduced grass redtop (Agrostis stolonifera) is often present on disturbed sites. Common Wet Prairie sedges are Carex lanuginosa, C. sartwellii, C. tetanica, and, in the west, C. praegracilis. Stiff rush (Juncus balticus) is frequently present. Forbs are abundant in Wet Prairies, but on the whole fewer forb species occur in Wet Prairie than in Mesic Prairie. Common widespread Wet Prairie forb species are panicled aster (Aster lanceolatus), New England aster (A. novae - angliae), meadow ragwort (Senecio pseudaureus), giant goldenrod (Solidago gigantea), Riddell's goldenrod (S. riddellii), giant sunflower (Helianthus giganteus), sawtooth sunflower (H. grosseserratus), sneezeweed (Helenium autumnale), gay - feather (Liatris pycnostachya), blazing -star (L. ligulistylis), grass- leaved goldenrod (Euthamia graminifolia), Indian hemp (Apocynum sibiricum), golden alexanders (Zizia aurea), closed gentian (Gentiana andrewsii), yellow star -grass (Hypoxis hirsuta), marsh vetchling (Lathyrus palustris), tall meadow rue (Thalictrum dasycarpum), prairie loosestrife (Lysimachia quadrora), Virginia mountain -mint (Pycnanthemum virginianum), swamp lousewort (Pedicularis lanceolata), and northern bog violet (Viola nephrophylla). Small willows (pussy willow and other willow species) and meadowsweet are common in the community; willow and aspen trees are also sometimes present, growing either singly or scattered in small clumps along wetland margins. Wet Prairie is a fire- dependent community, with shrub and tree cover increasing in the community in the absence of fire (though regular haying will also prevent increased shrub and tree cover in the community.) Wet Prairie occurs in low areas (such as depressions and drainageways) where the water table remains within the plant- rooting zone for several weeks during the growing season, but where inundation occurs only infrequently and briefly. In some Wet Prairies groundwater seepage causes soils to be very moist or wet. Wet Prairie is especially common on broad, poorly drained flats in the Glacial Lake Agassiz Interbeach Area, where there are many areas of artesian seepage. In the deciduous forest - woodland zone, Wet Prairie exists on broad, nearly level river terraces or in shallow depressions on outwash. The soils within the community are mainly mollisols (aquolls). They range in texture from silty clays to fine sands and are somewhat poorly drained to very poorly drained. Impermeable subsurface layers impede soil drainage on some sites, and a thin layer of muck may be present at Foxborough Conservation Development Restoration and Management Plan 23 the ground surface on Wet Prairies in seepage areas. Most soils are calcareous. Salt concentrations (sulfates of calcium and magnesium) high enough to influence the species composition of the community are present in the soils of Wet Prairies along the western edge of Minnesota,. primarily in the Agassiz Lacustrine Plain. On drier sites Wet Prairie often grades into wet -mesic stands of Mesic Prairie; on wet sites it often grades into Wet Meadow. Mesic Prairie, Wet Prairie, and Wet Meadow do not have well - defined floristic boundaries, and sometimes are difficult to separate from one - another in the field when they occur together. Shrub cover increases in Wet Prairie northward, and in the northern part of the community's range Wet Prairie often grades into Wet Brush - Prairie. Wet Prairie in southeastern Minnesota is distinctive from that elsewhere in the state, containing several species with restricted distribution. Floristic diversity is low in Wet Prairies in western Minnesota, but distinctive species assemblages occur there in association with saline sites. A comprehensive plant species list for Foxborough's Wet Prairie restoration areas is provided in Appendix B of this report. Wet Meadow Wet Meadow occurs within wetlands throughout all of Minnesota. The ground layer of the Wet Meadow community is composed of dense, closed stands of predominately wide - leaved sedges (e.g., Carex lacustris, C. stricta, C. aquatilis C. rostrata, C. haydenii) or grasses (e.g., Calamagrostis canadensis, C. inexpansa). Forb cover and diversity usually are high. Forbs such as spotted joe -pye weed (Eupatorium maculatum), common mint (Mentha arvensis), turtlehead (Chelone glabra), and swamp milkweed (Asclepias incarnata) are conspicuous. Shrub cover in Wet Meadows ranges from 0 to 70% and is composed of Bebb's willows and pussy willows. Mosses are rare or absent. Wet Meadow occurs on wet mineral soil, muck, or shallow peat ( <0.5 m). Standing water (generally stagnant) is present in the spring and after heavy rains, but the water table is generally below the soil surface for most of the growing season. The drawdown of the water table as the growing season progresses enables the oxidation of dead organic matter that has accumulated on the ground surface from previous years. This process makes available nutrients for some of the nutrient - demanding species present in the community. Occurrences of Wet Meadow along stream courses or adjacent to lakes often have fairly constant water levels relative to Wet Meadows in depressions or basins. On these sites siltation may be important in maintaining high nutrient levels. Wet Meadow tends to succeed to Shrub Swamp communities in the absence of fire, and therefore, there is a Shrub Subtype of the Wet Meadow community. Water -table lowering caused by drought or by ditching promotes succession of Wet Meadow to Shrub Swamps. Wet Meadows on organic soils, like other communities that occur on organic soils, recover very slowly, if at all, once altered by artificial flooding or draining A comprehensive plant species list for Foxborough's Wet Meadow restoration areas is provided in Appendix B of this report. Shallow/Mixed Emergent Marsh Mixed emergent marsh is dominated by wetland species other than cattails. Bulrushes are the most common dominants, especially hard - stemmed bulrush (Scirpus acutus), river bulrush Foxborough Conservation Development Restoration and Management Plan 24 • • • (Scirpus fluviatilis), softstem bulrush ( Scirpus validus), Scirpus americanus, and Scirpus heterochaetus. Common reed grass ( Phragmites australis), spike rushes (Eleocharis spp.), and (in some river backwaters) prairie cordgrass (Spartina pectinata) are less common dominants. In general, Mixed Emergent Marsh tends to occur on harder pond, lake, or river bottoms than Cattail Marsh and is less likely to contain the forbs that grow on the floating peat mats present in many cattail marshes. Broad - leaved arrowhead (Sagittaria latifolia) and aquatic macrophytes are the most common non - graminoid associates. Many Mixed Emergent Marsh species are sensitive to fertilizer run-off and other artificial disturbances, and disturbed Mixed Emergent Marshes (especially in the Prairie Zone) tend to convert to Cattail Marshes or become strongly dominated by reed canary grass (Phalaris arundinacea) or common reed grass (Phragmites australis), species that increase in abundance with disturbance. Mixed Emergent Marsh is a broad community type, encompassing all marshes dominated by species other than cattails. Therefore, sub - typing or recognition of new marsh types is likely following more thorough inventories of these marshes. New divisions most likely will be made according to dominant species or basin types (e.g., lacustrine versus riverine), or both. There are two geographic sections, a Forest Section and a Prairie Section. The dominant species in the Prairie Section tend to have a Great Plains distribution while those in the Forest Section tend to have a Great Lakes distribution. A comprehensive plant species list for Foxborough's Mixed Emergent Marsh restoration areas is provided in Appendix B of this report. V. Restoration and Management Tasks and Timeline The natural resource restoration and management recommendations contained within this section are divided into three sections: Pre - Construction Management Activities, Phase 1 Restoration and Site Recovery, and Phase 2 Maintenance and Adaptive Management. Pre - construction tasks were completed prior to or during site grading in spring 2005, to capitalize on time- sensitive natural resource conservation opportunities that would have otherwise been lost during site construction. Phase 1 includes natural resource restoration and management tasks designed to address the major ecological problems on the site, restore native vegetation to non - native landscapes, and improve the ecological structure and function of pre - existing natural community remnants. Phase 2 includes management and maintenance tasks that maintain the ecological structure and function of the site through time, and that adapt restoration and management prescriptions based on the ecological response of restoration areas following initial restoration treatments. Pre - Construction Restoration and Management Activities (Spring 2005) Forest and Woodland Native Plant Salvage Prior to initial site grading in April and May 2005, Royal Oaks Reality authorized Critical Connections Ecological Services to salvage local - ecotype native forest wildflowers, ferns, and sedges from former oak forest areas that would be graded for residential homes. CCES restoration crews salvaged 2,347 native woodland plants, and transplanted them into forested Foxborough Conservation Development Restoration and Management Plan 25 areas within Foxborough's conservation areas that lacked a diverse forest herbaceous layer. Plant species that were successfully salvaged and transplanted included: Interrupted Fern (Osmunda claytoniana), Pennsylvania Sedge (Carex pensylvanica, Trillium (Trillium cernuum), Woodland Sedge (Carex blanda), Peduncle Sedge (Carex pedunculata), Rosy sedge (Carex rosea), (Large Leaved Aster (Aster macrophyllus), Strawberry (Fragaria virginiana), Bedstraw (Galium triphyllum), Wild Geranium (Geranium maculata), Canada Mayflower (Maianthemum canadense), Sweet Cicely (Osmorhiza claytonii), Nightshade (Circaea lutetiana var. canadensis), Coltsfoot (Prenanthes alba), Wood Anemone (Anemone quinquefolia), Columbine (Aquilegia canadensis), Jack -in- the - Pulpit (Arisaema triphyllum), Starflower (Trientalis borealis), Small Bellflower (Uvularia sessifolia), White Avens (Geum canadensis), Early Meadow Rue (Thalictrum dioicum), and Rue Anemone (Thalictrum thalictroides). Common Buckthorn Removal within Forest Transplant Areas Prior to transplanting salvaged woodland plants, CCES restoration crews manually removed Common Buckthorn seedlings, saplings, and trees from species -poor forest areas within Foxborough's conservation areas. Buckthorn removal and soil preparation were necessary to help ensure successful transplanting of native woodland wildflowers, ferns, and sedges into forest restoration areas. Approximately 2.8 acres of forest were manually cleared of Common Buckthorn, and subsequently prepped and planted with native forest species salvaged from designated construction areas and fill areas. Additional cutting, removal, and herbicide treatments of these and other forest areas are planned for the late fall months in Phase 1 and Phase 2 of the restoration plan. Phase 1- Restoration and Site Recovery: Years 1— 5 The activities listed in Phase 1 are particularly critical to the first five years of site management. Changes in resource management prescriptions and implemented tasks during this time period should be reviewed by professional ecologists and project stakeholders to ensure that they are integrated and in agreement with other ongoing and proposed management tasks, and contribute to the overall quality of the site. Phase 1 Restoration and Management Priorities: 1) Control, remove, and manage invasive species - Common and Glossy Buckthorn, Tartarian Honeysuckle, Reed Canary Grass, and Spotted Knapweed. Reed Canary Grass within wetlands (and upland margins) and Common Buckthorn within forests and woodlands are the most problematic species present on the site, and their management should be of the utmost priority; 2) Restore native prairie vegetation to upland and transitional upland/wetland old- fields; 3) Conduct prescribed burning of Reed Canary Grass dominated wetland edges and Brome/Bluegrass dominated upland old fields; 4) Establish native species cover within wetland mitigation area and stormwater ponds, Monitor establishment of vegetation and hydrology within wetland mitigation area; Foxborough Conservation Development Restoration and Management Plan 26 • • • • 5) Selectively thin Aspen dominated wetland edges and woodlands to promote diverse native herbaceous plant communities, seed these areas as needed; 6) Monitor the site's response to initial restoration and management treatments, and refine management approach and methods as needed; 7) Install conservation area (outlot) boundary markers and interpretive signage that clearly defines the boundaries of the conservation area; 8) Install bituminous trail and boardwalks (at wetland crossings), re -seed trail edges with appropriate native species along trail edges and monitor weed species along trail corridor. Invasive Species Management Invasive species are clearly the most urgent management priority at Foxborough. Although invasive species have established on the site, there is ample time to manage the relatively concentrated populations of these species before they are able to spread further. However, if invasive exotic species are left unchecked and untreated, they will continue to invade, establish, and further degrade the remaining moderate quality natural vegetation within five to ten years time. Once established as reproductive populations, natural community restoration and management will be significantly more difficult and expensive within Foxborough's conservation areas. Common and Glossy Buckthorn Common Buckthorn (Rhamnus cathartica) and Glossy Buckthorn (R. frangula) are European shrubs that invade and establish within native forest and woodland understories in Minnesota. Once Buckthorn establishes within natural communities, it can out - compete most native species. Common Buckthorn was observed in various densities throughout the forest and woodlands of the Foxborough. Glossy Buckthorn prefers wetland habitats, and was observed in very limited numbers along wetland edges within the site. Removal and management of Buckthorn can be a labor intensive and costly undertaking. A long -term plan will likely be necessary to perpetually monitor and manage these species. The first phase of managing Buckthorn includes locating and removing all mature, fruit producing individuals, as to minimize seed dispersal and invasion. Seed producing plants are most commonly found along sunny woodland edges, rather than in woodland or forest interiors. The next phase of removal should include the removal of saplings and seedlings. When samplings and seedlings are removed, native shrub and herbaceous specious should be planted to reduce the risk of erosion, soil loss, and reinvasion of buckthorn and other undesirable species. CCES also recommends coordination with landowners adjacent to the Foxborough development, to secure permission to remove and treat buckthorn along adjacent property boundaries, where feasible. Replanting of native species on adjacent residential lands may be a necessary expense. Reed Canary Grass Reed Canary Grass (Phalaris arundinacea) is an invasive wetland grass that is very common to degraded wetlands within the Minneapolis /Saint Paul metropolitan area and throughout Minnesota. Reed Canary Grass is considered native to North America, but this species has been Foxborough Conservation Development Restoration and Management Plan 27 hybridized and cultivated as an aggressive and naturalizing forage grass that is also used erosion control in agricultural landscapes. Reed Canary Grass is pervasive in all wetlands and in upland edges of Foxborough's conservation areas. CCES recommends prompt management and treatment of Reed Canary Grass beginning in fall of 2005. Reed Canary Grass can be effectively managed with a grass - specific herbicide (Vantage) or non- specific herbicides (Rodeo and Round -Up), prescribed burning, and manual removal (where feasible). Spotted Knapweed Spotted Knapweed (Centaurea maculata) is an invasive weed from Eurasia, often colonizing in degraded sunny uplands, fallow agricultural fields, and remnant prairies. Spotted Knapweed was observed as scattered individuals throughout the old fields of Foxborough. This relatively sparse distribution suggests that immediate removal and treatment of this species would be very cost effective. In time, this species will become much more problematic within open grasslands, and will be much more difficult and expensive to remove and manage. Spotted Knapweed is best removed with a standard pitchfork, or spot treated with a Glyphosate -based herbicide (such as Round -Up). When manually removing these plants, it is very important to remove the entire root system and basal rosette of leaves. Herbicide treatments of Spotted Knapweed often require several repeated applications to completely eradicate an established population. Surface Runoff Management and Erosion Control Stormwater runoff and erosion control systems should remain in place and in working order throughout the development of residential lots and construction of homes at Foxborough. Regular scheduled monitoring and repair of these systems will significantly contribute to the overall success of the restoration of Foxborough's conservation areas, especially within wetlands. Erosion control structures and silt fences should be maintained along the conservation area boundaries until perennial vegetation is established within the adjacent residential lots. Once perennial vegetation has established, silt fences should be completely removed from the site and discarded. Restoration of Prairie Vegetation to Non Native Upland Old Fields Restoring the upland old fields to dry, mesic, and wet prairie vegetation is probably the largest task of the proposed management activities included in Phase 1. Appropriate communities have been prescribed (in Figure 6) based on soil texture, drainage, slope (steepness of grade), aspect (direction of slope - face), and landscape position. The dry-mesic -wet prairie continuum is dependant on variability in all of these abiotic landscape variables. Dry prairies tend to prefer dry, well - drained sandy soils on steep to moderate slopes that face east to southwest. Mesic prairies are tall -grass dominated communities that tend to prefer moderately drained to moist loamy soils on moderate and minor slopes. Wet prairies tend to prefer loamy soils that are perpetually saturated or seasonally flooded, and usually occur between wetland edges and native mesic prairies. Foxborough Conservation Development Restoration and Management Plan 28 • • • • • Appropriate seed mixes should be designed and purchased from native landscape nurseries to restore these three distinct community types. Wet prairie communities are less commonly restored within the Minneapolis/Saint Paul metropolitan area tan dry and mesic prairie types, due to limitations of suitable soil and hydrologic conditions. Native seed suppliers and nurseries may need to custom design a native wet prairie seed mix with the assistance of a professional and knowledgeable ecologist. However, mesic and dry prairies are commonly restored within the region, and quality seed mixes should be readily available from native plant suppliers. However, all seed mixes should be adjusted for the very sandy and relatively nutrient -poor soils typical of the Anoka Sand Plain and the Foxborough site. Seed mixes should be dormant seeded in September /October, or sown in the spring when the ground has thawed. To reduce costs and loss of plant material, seeds should be instead of plugs (potted plants); as plugs require more watering and protection from herbivory, and are generally more expensive to achieve a similar long -term result. Thinning and Management of Quaking Aspen along Wetland Edges The woodland edges that are prevalent along wetland edges in Foxborough's conservation areas are generally low - quality, species poor stands dominated by Quaking Aspen (Populus tremuloides). Such areas have likely established as a result of past land use practices, landscape - scale fire suppression, and partial drainage of wetlands. Furthermore, these woodland areas likely historically supported more diverse wet prairie and wet meadow natural communities. CCES has successfully restored similar aspen - dominated wetland edges to diverse prairie and wet meadow communities through selective thinning, removal, herbicide treatments, and prescribed burning of aspen. These management approaches often promote the re- establishment of diverse assemblages of herbaceous prairie and wetland species that require full to partial sun to germinate, reproduce, and persist along saturated wetland edges. Furthermore, in the absence of management, dense monotypic Aspen stands tend to promote the establishment of Buckthorn and Reed Canary Grass within the understory, and are prohibitive to prescribed burning due to fine fuel suppression. CCES recommends that selected areas of aspen woodland be carefully thinned and restored to more diverse and more easily managed natural community types such as wet prairie and wet meadow. However, selective thinning of aspen should first consider desired screening of adjacent land uses or other aesthetic considerations, and should balance restoration and management objectives with aesthetics. Maintain and Restore Soil Porosity in Developed Uplands Site grading and development of the residential lots at Foxborough will likely result in the pronounced compaction of surficial soil layers and reduced soil porosity within residential yards and conservation areas edges. CCES and the City of Lino Lakes recommend that prior to final landscaping of residential yards and installation of turf grass, sod, and other landscape plantings, compacted soil surfaces (upper 6 to 12 inches) of residential yards and edges of conservation areas should be roto -tilled and mixed with subsurface and topsoil layers to restore overall soil porosity and deep root establishment. Preparation of soils in this manner will increase overall soil porosity and stormwater infiltration, help to stabilize post - construction site hydrology, improve turf grass establishment, and reduce stormwater runoff and chemical runoff into the adjacent conservation areas. The City of Lino Lakes, Royal Oaks Reality, and the consulting Foxborough Conservation Development Restoration and Management Plan 29 ecologist should work with individual home builders, landscape contractors, and homeowners to ensure that this important site preparation step is accomplished on a lot by lot basis. Vegetation Establishment in Stormwater Ponds Stormwater treatment ponds within Foxborough's conservation areas have been excavated and rough graded during the initial site grading process in spring and summer of 2005. Water control structures, such as inlet and outlet pipes and weirs where installed prior to the initial grading of each stormwater basin. As required by the Minnesota Pollution Control Agency, silt fences have been installed along all edges of stormwater basins to minimize sedimentation of these basins or erosion of sediment into the surrounding conservation areas or off site wetlands. Stormwater treatment ponds will be fmal graded during the final phases of the overall site grading. Stormwater treatment ponds within the conservation area should be seeded and maintained as natural or semi - natural wetlands that compliment the surrounding natural communities within the conservation area. Therefore, only native, non - invasive plant species should be seeded into stormwater ponds. Native plant species that can tolerate fluctuating water levels and increased sediments, salt, and nutrients should be selected for each basin, and native seed mixes should be tailored to the design hydrology, soils, side slop e profiles, and topographic configurations of each stormwater treatment pond. Compensatory Wetland Mitigation Area A 1.99 -acre wetland mitigation area is under construction within the conservation area to mitigate for wetland impacts associated with the creation of residential lots and associated infrastructure within the Foxborough conservation development. This mitigation area has been excavated from a sandy upland knoll in the southeastern comer of the site during the site grading process in the summer of 2005. As required under the Minnesota Wetland Conservation Act rules, monitoring of the vegetation and hydrology of the mitigation area is required for a minimum of 5 years following completion of the wetland mitigation construction and planting. A mitigation monitoring plan will need to be developed in 2005 -2006, and will need to be implemented each year from 2006 through 2011. The Rice Creek Watershed District requires an annual wetland mitigation monitoring report at the end of each growing season during this 5 -year period following the initial construction of the compensatory wetland mitigation area. The mitigation monitoring report should include all data required under the Minnesota Wetland Conservation Act rules, such as monitoring of vegetation establishment, wetland hydrology, soils, and representative photographs from fixed photo - reference points, and any problems associated with the establishment of vegetation and hydrology as specified in the wetland mitigation plan.

Foxborough Conservation Development Restoration and Management Plan 31 Phase 2 - Maintenance and Adaptive Management: Years 5 -10+ Phase 2 of this restoration and management plan focuses on actions, which build on ecological improvements that were accomplished during the first five years of site management. Phase 2 also includes implementation of regular maintenance and monitoring, and augmentation of species diversity within establishing native communities and restoration areas. Phase 2 Management Priorities: 1) Monitoring and spot treatment of invasive species populations and effectiveness of management practices; 2) Prescribed burning of prairies, wetlands, savannas, and woodland edges; 3) Native seed collection and dispersal within restored natural areas; 4) Monitoring of restoration successes and failures, vegetation diversity, and wildlife use; 5) Monitoring and resolution of residential encroachment into conservation areas, unauthorized uses of conservation areas, and negative impacts associated with trail use and maintenance; 6) Coordination among the Foxborough Homeowners Association, the City of Lino Lakes, the project ecologist, and other project stakeholders to update management plan and priorities, and allocated restoration and management resources.

Prescribed Burning of Prairies, Savannas, and Woodland and Wetland Edges Develop prescribed burning plan, obtain burn permits, create burn breaks, and implement prescribed burning of wetlands, prairies, savannas, and woodland edges. Repeat as necessary. Spring through Fall 2010 through 2015 Native Seed Collection and Dispersal Collect native seed from established native restoration areas and disperse, as needed to similar suitable habitats within the conservation area. Annually 2010 through 2015 Coordination Among Stakeholders Coordinate among Foxborough's Homeowners Association, the City of Lino Lakes, consulting ecologists, and other stakeholders. Prioritize the use of limited management resources within the conservation areas. Annually 2010 through 2015 Monitor Conservation Area Boundaries and Trail Easement Monitor conservation area / residential lot common boundary, as well as trail easement for signage integrity and encroachment of non-conforming uses into conservation area. Resolve issues of non - conforming uses and boundaries. Annually 2010 through 2015 Monitoring and Adaptive Management Monitor restoration areas and identify problem areas. Adapt and refine management approaches to address these issues. Foxborough Conservation Development Restoration and Management Plan 32 • • • • VI. Socio - Cultural Considerations and Recommendations Signage Along Conservation Area /Residential Lot Boundaries Royal Oaks Realty will install and the Foxborough Homeowner Association will maintain, repair and, if necessary, replace the signage, which is placed within the conservation area. Wherever possible and reasonable, conservation area signage will be installed during the initial land development phase of the Foxborough Conservation Development (Fall 2005/ Spring 2006). Royal Oaks Realty will post up to four (4) signs along any residential lot line that adjoins the conservation areas / outlots. Signage will also be placed in other locations within the conservation area, as determined as necessary by the Royal Oaks Reality and the City of Lino Lakes. The residential owner of each lot adjacent to the conservation area may not remove, alter or damage the signs. Conservation area signage should be designed to be easily recognizable, durable, and resistant damage by prescribed burning and other stresses associated with restoration and management of the conservation areas. Signage should be tall enough (at least 3 to 4 feet) to stand above native perennial prairie grasses and low shrubs, taking into account the height of mature restored native vegetation within each restoration and management area. Trails A public pedestrian trail has been planned within outermost conservation area outlot (Outlot A) that will transect the conservation area and provide access from adjacent neighborhoods to future city and regional trail corridors. The trail easement and infrastructure will be owned and maintained by the City of Lino Lakes. Figure 7 illustrates the final alignment of this trail. As of August 2005, the trail alignment has been field - located and surveyed, and initial brush clearing and grading has been completed. Trail construction will occur in the fall of 2005 and is planned for completion by early summer 2006. The trail will be constructed of bituminous asphalt over a Class 5 gravel subsurface. Boardwalks will be installed to cross wetlands and low -lying areas. Raised boardwalks (on piers or footings) are typically more ecologically sensitive than floating boardwalks, in that raised structures allow emergent and aquatic vegetation to persist below the walking surface. Furthermore, elevated boardwalks are less likely to create barriers to most plant and animal dispersal. However, raised boardwalks are generally more costly than floating boardwalks. Native and non - invasive plant species should be seeded and established along the trail corridor following trail construction, consistent with the natural communities the trail transects. Monitoring and management of problematic weed establishment along the trail corridor should be conducted on an annual basis, as weed seeds are likely to be introduced by trail users along the trail corridor. Although the trail may be cleared of snow by plowing or shoveling, road salt and sand should not be used to manage snow or ice within the conservation areas. Additional narrow footpaths and unpaved trails may be planned or deemed necessary by the Foxborough Homeowners Association within the conservation areas. Trail and path alignment should be sensitive to maintaining the integrity of the natural communities they transect. Foxborough Conservation Development Restoration and Management Plan 33 Figure 7. Final Trail Alignment within the Foxborough Conservation Development (August 2006) Trail Easement and Alignment Highlighted in Yellow Foxborough Conservation Development Restoration and Management Plan 34 • • • Appropriate Uses Foxborough's conservation areas will be managed as a natural open space with a passive recreational trail corridor. Therefore, appropriate uses are limited to passive recreational activities, such as: walking, running, nature and wildlife observation, ecological studies and such other activities approved by the Foxborough Homeowners Association that will not disrupt or degrade the ecological integrity of the site's natural resources and restoration areas. Biking and dog walking may be considered as appropriate uses, should the site serve as a connection to a regional bike path or wallcing path. However, such activities may disrupt natural areas, especially when trail users stray from the designated trail corridor. Yard debris or commercial landscape refuse should not be composted or disposed of within the conservation areas. Furthermore, residential homeowners with yards adjoining the conservation areas should avoid encroachment into designated outlots. Active recreational facilities, such as athletic fields and playgrounds, are not considered appropriate uses for the conservation area. Artificial lighting should be carefully sighted close to trail entrances and roads, and trail use may be limited to daylight hours. VII. Recommendations for Monitoring & Adaptive Management Ecological restoration and management is a process that involves adaptive decision making by natural resource and planning professionals. Implementation of management activities are designed to change natural community structure and functions, and these changes will likely influence established management plans and strategies. For this reason, it is important to monitor the results of implemented management activities and assess if changes to management plans need to be made based on these observations. To maximize the effectiveness of restoration and management actions and the likelihood of achieving desired natural resource management goals, it is important to monitor chosen aspects of restoration and management projects on a regular basis. Monitoring can be an expensive and labor - intensive process, or it may be done through simple observations of environmental changes over time. Deciding what to monitor and how extensive this monitoring should be are always difficult tasks. The level of effort in monitoring will vary depending on available resources, staff, and/or qualified volunteers that may carry out monitoring tasks. At a minimum, the environmental characteristics that should be monitored within Foxborough's conservation areas include: 1) The abundance and extent of invasive species, and the effect of management approaches in reducing and limiting invasive species abundance over time; 2) The effects and relative success and failure of restoration and management actions to achieve desired management goals over time; 3) The success of native restoration planting establishment, including species diversity, seedling germination success, secondary weed species infestations, and opportunities for natural community improvement over time; Foxborough Conservation Development Restoration and Management Plan 35 4) Establishment of vegetation and design hydrology within wetland mitigation areas and stormwater wetlands, as well as sedimentation and/or erosion and integrity of hydrologic infrastructure; 5) Changes in plant and wildlife diversity and wildlife habitat use within the restoration areas; 6) Impacts of human use to the conservation areas' natural and cultural amenities, such as trampling of restored vegetation, soil compaction, integrity of trails and signage, erosion, weed introductions, dog walking and fecal matter, yard refuse and garbage, unauthorized pesticide and fertilizer use.

Communicating environmental initiatives in the city using various means of communication, i.e., City WebPages, newsletter, homeowner's association meetings, the information kiosk, and press coverage. Pursue providing articles and information to the local media. B Promote individual Backyard Wildlife Habitat through the National Wildlife Federation. Inventory current participants and work to expand program. This one has not gone anywhere We do promote wildlife habitat in conservation development types of projects, and in the use of water and native materials in non - conservation development projects We should talk more about this, • Participate in Blue Heron Days, providing educational material to the public. • Participate in Earth Day activities in the community, promoting environmental awareness and collaboration with other environmental focused organizations. • Monitor all activity in the 35W corridor as well as other proposed development areas, focusing on the values Lino Lakes citizens have expressed in the vision for our city and the unique ecological aspects of our wetlands, lakes and streams and subsurface waters. Apply mitigation plan as defined for that area. We also have a lot of planning going on in the AUAR 35E Corridor • Perform an evaluation of past Environmental Board recommendations for development projects. Review a sampling of a variety of projects by site visits, discussion with city staff, and landowners, neighbors, on the outcomes of the Boards recommendations. Submit a summary of significant findings resulting from the review in writing to the Community Development Director and then forward report to city council I think this is an ongoing goal that does not necessarily resolve itself for any one project after one inspection and discussion particularly if Environmental Board recommendations involve restoration work • Promote conservation development within the City incorporating the Open Space/Trail Plan and Handbook for Environmental Planning and Conservation Development. Maybe in the new Comp Plan and Resource Management Plan as well We should have some kind of a statement on the Comp Plan /RMP I think as a basis for improving the way we develop to encourage the saving and restoration of unique resources • To meet or exceed our City recycling goal of 50 percent or greater of our Municipal solid waste. Find innovative ways to promote and encourage recycling as a city. Add recycling materials to kiosk. • Continue to monitor the Heron rookery and water quality in the northern one third of Peltier Lake and to support the protection of resources in that area. • Participate in comp plan and process • Review and comment on the RMP planning process for the City of Lino Lakes, JD4 and TMDL study for the Rice Creek Chain of Lakes. Maybe this statement should include something about the RMP as an underpinning or layer to be used to model the development of the new Comprehensive Plan. Support the adoption and implementation of the Lino Lakes Resource Management Plan • • Participate in school nature project at Centennial Middle School. We have this one going and will hopefully include some major restoration /education projects this spring • Review Conservation Developments for conformance to yearly Conservation Easement work. There is approximately $17, 000 available for 2008 in Foxburough • Continue to support the Stream Health Evaluation Program (SHEP) NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF LINO LAKES, MINNESOTA: 1.
