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 High Wetland water quality is high, indicating little need for additional <br /> Wetland Water treatment. As long as upland land use and existing buffer conditions do <br /> Quality not change, this wetland can be expected to sustain current <br /> characteristics. <br /> Shoreline Protection Not The site does not fringe a deepwater habitat, lake, or is not within any <br /> Applicable type of watercourse. <br /> Maintenance of Exceptional The site is known to be used by rare or state or federally-listed wildlife <br /> Characteristic species OR has a scarce or rare wetland plant community and a high <br /> Wildlife Habitat vegetative community quality rating. In either case, the wetland is <br /> Structure exceptional for local priorities or under state or federal guidelines. <br /> Maintenance of Moderate Permanently flooded but isolated wetlands can support native <br /> Characteristic Fish populations of minnows and some isolated deep marshes have <br /> Habitat intermittent populations of sunfish and northern pike after flood events. <br /> Poor water quality, due to runoff and insufficient buffer and vegetation, <br /> can affect the sustainability of fish populations. <br /> Maintenance of Moderate Predatory fish may be present due to occasional connection to other <br /> Characteristic waters. Winter habitat unreliable if shallow water allows winterkill. As <br /> Amphibian Habitat with fish, excess sedimentation may smother eggs so pretreatment of <br /> stormwater runoff and a wide, unmanicured buffer improves conditions <br /> for reproduction. Barriers to migration may also impact the value of a <br /> site to more-mobile frogs, salamanders, and turtles. <br /> Aesthetics/Recreation Moderate Many wetlands are visible from nearby buildings or roads and are <br /> /Education/Cultural accessible for some recreational activities. Excess negative human <br /> influence (such as trash or alteration) will reduce the ranking of well- <br /> used and highly-accessible sites. <br /> Wetland restoration Not Because restoration would affect permanent structures or infrastructure <br /> potential Applicable (houses, roads, septic systems), this site is not suitable for restoration. <br /> Wetland Sensitivity to Exceptional This site is exceptionally sensitive to stormwater; sedge meadows, open <br /> Stormwater and and coniferous bogs, calcareous fens, low prairies, wet to wet-mesic <br /> Urban Development prairies, coniferous swamps, lowland hardwood swamps, or seasonally <br /> flooded basins. <br /> Page 3 of 4 <br />
