Mounds View Silver View Park Pond nonnative black locust. However, the canopy removal will enable better establishment of continuous ground layer vegetation for improved water infiltration and slope stabilization along the drainage. Oak trees and other hardwoods can then be planted to fill in the canopy. Cottonwood and red pine are not typically in Pin Oak—Bur Oak Woodland but are currently present and can be maintained as part of the canopy composition. Vegetation Management Goal • Plant community resembling Pin Oak—Bur Oak Woodland (FDs37b)with improved wildlife habitat, native plant diversity, and water infiltration capacity. Vegetation Management Objectives • Canopy cover is over 50% and dominated by bur oak and white oak, with occasional black cherry, red pine, and cottonwood. Pin oak and northern red oak are avoided for supplemental planting due to their high susceptibility to oak wilt. • All invasive, nonnative trees (primarily black locust) and saplings are removed. Native trees will need to be planted to increase canopy cover after invasive, nonnative trees are removed. • Native shrub cover is about 10-25% and composed of species such as black raspberry, red- berried elder, gooseberry, chokecherry, American hazelnut, and gray dogwood. • Invasive, nonnative shrub cover(common buckthorn, glossy buckthorn, tartarian honeysuckle) is reduced to less than 5%. • Herbaceous ground layer vegetation cover is increased to over 75%and dominated by native grasses, sedges, and forbs, such as those listed in the table below. Invasive, nonnative herbaceous cover is less than 5%. • Nearly continuous ground layer cover is maintained to promote water infiltration and soil stabilization. • Diverse ground layer vegetation is established using native seed mixes and plugs that include species that can provide floral resources for pollinators throughout the growing season.
