RESULTS <br /> Vegetation <br /> The Nelson Restoration site consists of several plant communities, which have been classified <br /> as Wet Meadow(approximately 38%of the site), Deep Marsh (approximately 9%of the site), <br /> Enhanced Lowland Forest (approximately 14%of the site) and Enhanced Upland Forest <br /> (approximately 37%of the site). Figure 2 illustrates the site's designed plant communities, and <br /> Table 2 represents the acres planned and observed for each plant community. <br /> Table 2.Vegetative communities planned and observed: <br /> Plant Community Acres Planned Acres Observed <br /> Wet Meadow* 2.14 2.14 <br /> Deep Marsh* 0.50 0.50 <br /> Enhanced Lowland Forest(wetland portion)* 0.35 0.35 <br /> Enhanced Lowland Forest(upland portion) 0.47 0.47 <br /> Enhanced Upland Forest 2.07 2.07 <br /> Wetland Edge Plantings(road bank ofTonkawa Road) 0.08 0.08 <br /> Rain Garden (Wet Meadow) 0.05 0.05 <br /> Total Wetland Area 2.98 2.98 <br /> Total Upland Area 1 2.68 2.68 <br /> Total Area 5.66 5.66 <br /> *Vegetation communities used to calculate Total Wetland area. <br /> Restored/enhanced plant communities reflected the acres designed, but the geometry of the <br /> Deep Marsh was adjusted during construction (Figure 3). This field adjustment consisted of <br /> shifting the Deep Marsh slightly west to avoid excavation of the shallower wetland soils at the <br /> eastern edge of the existing wetland. The 0.5-acre size of the designed Deep Marsh was <br /> maintained. <br /> • Wet Meadow-Thirty-two plant species were documented in the Wet Meadow; <br /> dominant species included tall manna grass (Glyceria grandis), curlytop knotweed <br /> (Persicaria lapathifolia), and purple loosestrife (Lythrum salicaria). In addition to the <br /> "plant community" species list and percent coverages, a 10mx10m plot was established <br /> in this dominant plant community to provide a more detailed assessment of a <br /> representative area (Figure 3). Table 3a presents all plant species documented in the <br /> site's Wet Meadow as well as the Wet Meadow plot. <br /> • Deep Marsh- Eight plant species were documented in the Deep Marsh;the most <br /> dominant species (10%cover)was narrow-leaved cattail (Typha angustifolia) or its <br /> hybrid. Table 3b presents all plant species documented in the site's Deep Marsh. <br /> • Enhanced Lowland Forest-Thirty-one species were documented in the Enhanced <br /> Lowland Forest; dominant species included green ash (Froxinus pennsylvanica), spotted <br /> MN Board of Water and Soil Resources <br /> Nelson Restoration Site(12-0975)—2015 Monitoring Report 4 <br />
