We compare this to the <br /> biological communities we anticipate will result from restoration activities. In brief,the site's <br /> wetland currently consists primarily of a degraded Shallow Marsh,dominated by invasive <br /> cattails, purple loosestrife,and reed canary grass. The proposed wetland is designed to consist <br /> of a large,diverse Wet Meadow with an area of Deep Marsh. <br /> EXISTING VS.PROPOSED BIOTA <br /> The following table provides metrics for comparing existing and proposed biological <br /> communities(pre-and post-construction)at the Nelson Restoration site wetland. Some <br /> existing conditions values were estimated. All proposed conditions values were estimated. <br /> Proposed conditions are for two to three years post-construction. Estimates were based on our <br /> professional experience in comparable wetlands in the region and expected, realistic <br /> restoration outcomes. <br /> Category Metric Under Existing Under Proposed <br /> Conditions Conditions <br /> Size Shallow Marsh(acres) 2.4 0 <br /> Fresh Wet Meadow(acres) 0.3 2.2 <br /> Hardwood Swamp(acres) 0.3 0.3 <br /> Deep Marsh(acres) 0 0.5 <br /> Vegetation Percent Invasive Cover(96) <br /> Condition 90 <20 <br /> Tree Species Richness(#) 4 6 <br /> Shrub Species Richness(#) 4 8 <br /> Grass Species Richness(#) 3 1012 <br /> Sedge Species Richness(#) 2 10±2 <br /> Forb Species Richness(#) 15 30±5 <br /> Wildlife Use Bird Species Richness(annual,#) 6* 18±4 <br /> Amphibian Species Richness(breeding,#) 0* 4±1 <br /> Dragonfly/Damselfly Species Richness(#) 4* 12±2 <br /> Fish Species Richness(#) 0 2±2 <br /> Note: *Values based on site-specific field data collected by AES in 2014. <br /> Sustainable Solutions for Over 30 Years. www.appliedeco.com <br />
