Mounds View Silver View Park Pond <br /> 4.1.1 TREE REMOVAL <br /> Tree removal is recommended for invasive, nonnative trees throughout the project area and for select <br /> native trees in the areas recommended for Bur Oak—Pin Oak Woodland restoration. The black locust <br /> stands near Silver Lake Road will involve the bulk of the tree removal effort. Invasive trees are otherwise <br /> scattered through the Lowland Hardwood areas. <br /> Tree removals should be planned for dormant seasons with frozen ground conditions to minimize ground <br /> disturbance and impacts to understory vegetation. Stumps should be treated with herbicide specifically <br /> proven to kill the root systems and prevent re-sprouts of target trees. <br /> Black locust and white poplar are prolific at root suckering, so any existing suckers should be cut and <br /> treated as well. Seedlings and saplings of black locust, white poplar, white mulberry, Siberian elm, and <br /> Amur maple will need to be spot treated by foliar applications during the growing season or cut/stump <br /> treatments. Eliminating these tree species elsewhere in the park will help eliminate seed production and <br /> potential re-colonization of the project area. <br /> Tree removal bids can be solicited on a cost per acre or on a per-tree basis, depending upon the scale of <br /> a restoration project. For the relatively small scale of work at Silver View Park, conducting an inventory of <br /> trees slated for removal and field marking each tree will enable development of more detailed bid <br /> specifications for more accurate contractor pricing. <br /> 4.1.2 INVASIVE SHRUB CONTROL <br /> Invasive shrub control will primarily involve common buckthorn, but glossy buckthorn,Tartarian <br /> honeysuckle and shrub/sapling-sized invasive trees should be included in this activity as well. Buckthorn <br /> ranges in size from seedlings to trees that are over 3-4" in diameter. <br /> As with the tree removal, invasive shrubs and saplings should be removed during dormant conditions. In <br /> the wetlands, invasive shrub removal should take place when the ground is frozen as well. All invasive <br /> shrubs and saplings should be cut as close to the ground as possible and cut stumps promptly treated <br /> with herbicide. Cut material can be chipped and hauled off for composting. Forestry mowing to shred cut <br /> material is an alternative to chipping and hauling for areas accessible by a skidsteer. <br /> Follow-up foliar treatments should be anticipated for any stump re-sprouts and seedlings. If there is <br /> desirable native broadleaf ground cover in areas with re-sprouts and seedlings, foliar treatment should <br /> occur after the native broadleaf plants have senesced in the fall.Areas with sparse or no desirable <br /> broadleaf plants can be foliar treated during the growing season. A minimum of three to five years of <br /> follow-up foliar treatments should be anticipated to significantly reduce invasive shrub cover and control <br /> recruitment from the soil seedbank. <br /> Prior to invasive shrub control, a seeding/planting plan should be in place for revegetation. A seed mix of <br /> native grasses and sedges is typically sown in areas where invasive shrubs will require follow-up foliar <br /> treatments with a broadleaf-selective herbicide. After the invasive shrub cover has significantly <br /> Project Number: 193806465 20 <br />
