This wetland represents pre-European settlement conditions. <br /> The following plant communities were observed: <br /> (See Appendix A for details on the Dominant Species per plant community) <br /> Hardwood Swamp Type 7, PF01 A. This community had a vegetative index of moderate and comprised 10 <br /> percent of the entire area. <br /> Fresh Wet Meadow Type 2, PEM1 B. This community had a vegetative index of moderate and comprised 75 <br /> percent of the entire area. <br /> Deep Marsh Type 4, PUBF. This community had a vegetative index of moderate and comprised 15 percent <br /> of the entire area. <br /> The highest rated community was the Hardwood Swamp community rated at 0.5. Averaging all the <br /> communities together, the Vegetative Diversity and Integrity of this wetland is Exceptional. A more accurate <br /> look uses a weighted average; using this method, this site shows a Exceptional Vegetative Diversity and <br /> Integrity. <br /> One or all three of the following are present: 1) highly diverse wetlands with virtually no non-native species, 2) <br /> rare or critically impaired wetland communities in the watershed, or 3) the presence or previous sighting of <br /> rare, threatened, or endangered plant species. Regardless of the quality or quantity of other communities, the <br /> presence of one of these will move the ranking of the entire site. <br /> Functional Ratings <br /> Function Rating Comment <br /> Vegetative Diversity Exceptional One or all three of the following are present: 1) highly diverse wetlands <br /> with virtually no non-native species, 2) rare or critically impaired wetland <br /> communities in the watershed, or 3) the presence or previous sighting <br /> of rare, threatened, or endangered plant species. <br /> Additional stormwater High Because the maintenance of wetland water quality index is high, no <br /> treatment needs additional treatment is called for. <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 altered 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 /> Page 2 of 4 <br />
