Mounds View Silver View Park Pond Wetland restoration is recommended to improve protection of water quality, provide higher quality wildlife habitat, and sustain diverse native plant communities. Removing invasive shrubs in the understory as part of the restoration process will also enhance park user views of the wetland habitat, pond, and associated wildlife. Northern Wet Meadow/Carr(WMn82) is recommended as a target native plant community for all but the forested portion of the wetland complex. Northern Wet Meadow/Carr is an open wetland with continuous cover by grasses, sedges, and forbs adapted to saturated soils and periodic inundation. When this wetland community has over 25% shrub cover, it is classified by the MN DNR as Willow—Dogwood Shrub Swamp (WMn82a). Several species of willow, red-osier dogwood, speckled alder, and sometimes bog birch may be present.A MN DNR fact sheet describing this wetland plant community is available at the following weblink: https.//files.dnr.state.mn.us/natural resources/npc/wet meadow carr/wmn82.pdf For the forested portion of the wetland complex, the community should remain forested as a"Hardwood Swamp" but can be significantly enhanced through invasive shrub removal and native seeding/planting. Vegetation Management Goal • Wetlands resembling Northern Wet Meadow/Carr and Hardwood Swamp with improved water filtration capacity, wildlife habitat, and native plant diversity. Northern Wet Meadow/Carr Vegetation Management Objectives • Canopy cover is absent to sparse. Trees present may include species such as ash, elm, cottonwood, boxelder, quaking aspen, and willow. • Shrub cover may be variable, ranging from sparse to intermittent(0-75%) across the wetland complex. Shrub cover is dominated by native species such as red-osier dogwood and willows. • Invasive shrub cover is reduced to less than 5%. • Herbaceous ground layer cover is increased to over 75%throughout and composed of diverse native herbaceous species, represented by wetland grasses, sedges, and forbs. Hardwood Swamp Vegetation Management Objectives • Canopy cover is intermittent to continuous (over 75%)and composed of native hardwoods such as cottonwood, boxelder, hackberry, and elm. • Subcanopy cover may be present, variable in cover, and composed of native canopy species. • Shrub/sapling layer cover is 25-75%, composed of native wetland shrubs such as elderberry, willow, red-osier dogwood, silky dogwood, and nannyberry. • Herbaceous ground layer cover is increased to over 50%, with a diverse composition of native shade-tolerant wetland grasses, sedges, and forbs.
