Foxborough Conservation Development, Lino Lakes, Minnesota Proposed Restoration and Management for 2011 Scope of Work and Cost Estimate Critical Connections Ecological Services, Inc. Page 2 of 3 A CCES restoration crew will treat buckthorn with a Glyphosate based herbicide in two ways throughout the conservation outlots. The first method for buckthorn treatment will involve a foliar application of herbicide in areas with lower stem densities of buckthorn. Once the herbicide treatment is complete the stems will be left standing since after the next prescribed burn within the outlots is implemented they will then likely be brought down to the groundlayer. The second method for buckthorn treatment involves the cutting, removing, and treating of the cut stump with herbicide. This method will be used n areas where higher stem densities of buckthorn occur such as in the northwest corner of Foxborough in Outlot E. Task 1 Timeline: August through November 2011 Task 1 Costs: $4,000 (Labor and Herbicide) Task 2: Continued Management of Reed Canarygrass A CCES restoration crew will treat with herbicide areas dominated by reed canary grass within the outlots of Foxborough that have not been treated yet, as well as perform follow -up spot treatment to areas that were sprayed with herbicide during 2009 and 2010. The areas to be treated in 2011 are primarily located in the northeastern part of the development within Outlots A, B, and C where reed canarygrass dominates much of the low -lying areas. Areas throughout Foxborough that were initially treated during 2009 and 2010 still have a few clumps of reed canarygrass persisting and will need to be spot treated as necessary. Areas treated in 2009 and 2010 that will be spot treated include the northern wetland fringe and uplands of the wetland mitigation area, natural wetlands along the trail corridor, and several stormwater basins. Reed canary grass will be treated with Glyphosate herbicide when it occurs in monotypic stands, and Sethoxydim (grass specific) herbicide when it occurs intermittently with other desirable native species. Task 2 Timeline: August through October 2011 Task 2 Costs: $3,700 (Labor and Herbicide) Task 3: Continued Management of Other Invasive Species and Noxious Weeds Other invasive species and noxious weeds, such as Canada thistle, narrow leaf and hybrid cattail, spotted knapweed, birds -foot trefoil, and yellow and white sweet clover that were initially treated in 2009 and again in 2010, will be followed up with a spot herbicide treatment in 2011. A CCES restoration crew will spot treat the areas of invasive species and noxious weeds that require an additional herbicide treatment for more complete control. These invasive species and noxious weeds are located within several of the outlots within Foxborough and can be found mainly along the trail corridor where past grading and trail construction activity took place. A CCES restoration crew will chemically treat these other invasive species and noxious weeds with a Glyphosate based herbicides (such as Roundup and Aqua Neat). Task 3 Timeline: Task 3 Costs: July through October 2011 $1,000 (Labor and Herbicide)
