The highest rated community was the Fresh Wet Meadow community rated at 0.5. Averaging all the <br /> communities together, the Vegetative Diversity and Integrity of this wetland is Moderate. A more accurate <br /> look uses a weighted average; using this method, this site shows a Moderate Vegetative Diversity and <br /> Integrity. <br /> The weighted average provides the best measure for an entire wetland. Plant communities at this site are, <br /> overall, of average quality. Individual community ratings should be examined to provide a complete picture of <br /> possible high-value communities or smaller-but-poor-quality segments that might degrade the site over time. <br /> Functional Ratinas <br /> Function Rating Comment <br /> Vegetative Diversity Moderate Moderate-functioning vegetative communities indicate a presence of <br /> native wetland species with substantial non-native or invasive species. <br /> Additional stormwater Moderate Sediment removal would improve the ability of this site to maintain water <br /> treatment needs quality. <br /> Maintenance of Moderate There has been some degree of human alteration of the wetland <br /> Hydrologic Regime hydrology, either by outlet control or by altering immediate watershed <br /> conditions. However, the wetland retains some of the hydrologic regime <br /> similar to the original wetland type, either in part of the wetland or <br /> overall to some extent. Because of the interference (whether active or <br /> inadvertant), some characteristic vegetative communities have likely <br /> been affected, as also have the functions of flood attenuation, water <br /> quality and groundwater interaction. <br /> Flood/Stormwater/Att Moderate The wetland provides some flood storage and/or flood wave <br /> enuation attenuation. It may have either an attered or unrestricted outlet, <br /> disturbed wetland soils, thin or little emergent vegetation (with channels) <br /> or it may be situated high in a watershed with a low proportion of <br /> impervious surfaces, moderate runoff volumes, loamy upland soils, and <br /> one or more other wetlands present within the subwatershed. <br /> Downstream Water Moderate This wetland has some ability and opportunity to protect downstream <br /> Quality resources. The ability of the wetland to remove sediment from <br /> stormwater is determined by emergent vegetation and overland flow <br /> characteristics. A high nutrient removal rating indicates dense <br /> vegetation and sheet flow to maximize nutrient uptake and residence <br /> time within the wetland. The opportunity for a wetland to protect a <br /> valuable water resource diminishes with distance from the wetland so <br /> wetlands with valuable waters within 0.5 miles downstream have the <br /> greatest opportunity to provide protection, as do those that receive more <br /> (and less-treated) runoff. <br /> Maintenance of Moderate Wetland water quality is average. Sediment removal from incoming <br /> Wetland Water water would benefit the site. Also consider reducing the amount of <br /> Quality stormwater directed at the site. Sustaining a diverse wetland may <br /> require additional control over upland land use and the buffer. <br /> Shoreline Protection Not The site does not fringe a deepwater habitat, lake, or is not within any <br /> Appiicable type of watercourse. <br /> Page 2 of 4 <br />
