Mounds View Silver View Park Pond <br />3.1 Dry-Mesic Oak Woodland Existing Cover Type <br />Two small upland wooded areas near Pond EW-4.P3 comprise a total of about 0.5-acre of dry-mesic oak <br />woodland with canopy cover dominated by bur and pin oaks that range from 8 inches to over 24 inches in <br />diameter at breast height (DBH). A few oaks southwest of the pond are over 30-inch DBH. The oaks in <br />this cover type are visible in a 1940 aerial photo, Figure 3, when the site was farmed, and the woodland <br />areas were likely grazed. <br />Boxelder was common in the canopy during the 2023 survey, along with a few black cherry and invasive, <br />nonnative white mulberry. Some of the oaks had a somewhat open -grown growth habit, reflecting the <br />more open historic growing conditions. Boxelder occurred occasionally beneath the oak canopy as well, <br />along with a few American elm, pin oak, nonnative Norway maple, and nonnative, invasive Amur maple. <br />The shrub/sapling layers of the woodlands were dominated by common buckthorn, with occasional green <br />ash. Native shrubs such as black raspberry and red -berried elder were present but infrequent. Ground <br />cover was generally sparse, but most often composed of the native vine Virginia creeper and the native <br />forb white snakeroot, with occasional native violets and nonnative, invasive garlic mustard. Overall, the <br />oak canopy and old -growth oak trees are unique and notable features for upland vegetation within the <br />project area. <br />Due to the old -growth oaks in this cover type, restoration towards a native plant community (NPC) <br />resembling Pin Oak — Bur Oak Woodland (FDs37b) is recommended. This woodland NPC has been <br />mapped and described based on vegetation plots sampled by the Minnesota Biological Survey. The <br />following weblink provides a MN DNR fact sheet describing the vegetation structure and composition, <br />landscape setting and soils, and natural history of Pin Oak — Bur Oak Woodlands. <br />httos://files.dnr.state.mn.us/natural resources/noc/fire dependent forest/fds37.Ddf <br />Vegetation Management Goal <br />• Restore to a plant community resembling Pin Oak — Bur Oak Woodland (FDs37b) with improved <br />wildlife habitat, native plant diversity, and water infiltration capacity. <br />Vegetation Management Objectives <br />• Canopy cover is over 50% and dominated by bur oak and pin oak, with occasional black cherry. <br />Boxelder and American elm are removed from the canopy and understory to reduce competition <br />with oaks and increase light to ground layer vegetation. <br />• All invasive, nonnative trees (white mulberry, Norway maple, and Amur maple) and saplings are <br />removed. <br />• Native shrub cover is about 25-50% and composed of species such as black raspberry, red - <br />berried elder, gooseberry, chokecherry, American hazelnut, and gray dogwood. Tree saplings of <br />green ash, boxelder, hackberry, and elm are eliminated. <br />Insert zoomed in map of area, so the reader does not have to flip back to the larger map for reference <br />Project Number: 193806465 8 <br />
