Mounds View Silver View Park Pond disconnected from the shoreline. Native shrubs such as red -osier dogwood, gray dogwood, and elderberry were common to occasional. Ground cover ranged from sparse to continuous, with areas of open canopy more likely to have continuous cover by nonnative grasses such as smooth brome, Kentucky bluegrass, or reed canary grass. White snakeroot, a disturbance -adapted native forb, was the most commonly encountered native forb. Garlic mustard, creeping Charlie, purple loosestrife, leafy spurge, and Canada thistle are problematic broadleaf invasive plants associated with this cover type. Several trees have been planted along the north shoreline in canopy gaps. Planted species noted during the 2023 field surveys included sycamore, bald cypress, tamarack, hackberry, and Kentucky coffee tree. Shoreline vegetation cover in the mapped lowland hardwoods cover type is in general a sensitive and important feature for stabilizing the banks of the pond and creating diverse wildlife habitat. Several wood ducks were observed during both field visits foraging in the south arm of the pond where woody vegetation hangs over shallow water and downed trees/branches are present. Maintaining lowland hardwood cover is recommended for all of the areas mapped as that cover type based on 2023 observations. Vegetation management objectives focus on removal of invasive, nonnative plants, increasing native short-statured herbaceous cover and species diversity, and enhancing pond and wildlife views. Some shoreline locations may require installation of bank stabilization features along with invasive plant removal and revegetation with native plant materials. In some areas, including the west side of the south pond lobe, the existing bituminous loop path is near the shoreline; combined with existing steep, eroded shoreline banks, long-term maintenance of a stable Insert map of shoreline will be difficult. The existing bituminous path is also showing signs of degradation with trail horizontal and longitudinal pavement cracking in some areas. We recommend shifting the path further location(s) to from the shore when reconstructing it to reduce shoreline slopes where it is steep and eroded, in order tobe relocated improve shoreline stability and ease of long-term maintenance. Vegetation Management Goal • Lowland hardwood plant communities with improved shoreline stabilization capacity, pond buffer qualities, wildlife habitat, native plant diversity, and enhanced views of the pond and associated wildlife.
