Exhibit J- <br />additional weeds and invasive species are also present. <br />Lakeside Vegetation <br />Lakeside vegetation is present, surrounding the 3.6-acre lake in the north-central portion of the <br />Expansion Area. Early successional species are common throughout the area. Knotweeds, <br />willows, cattails, and reed canary grass dominate the area. There are also several small plains <br />cottonwoods. <br />Saltgrass Draw <br />This area is within the historic meander of the river but is now completely dry. Inland saltgrass <br />was the only dominant species observed in this area. On the north side of the draw several very <br />old prairie dog burrows were observed. On the south side several active and inactive holes were <br />observed. No prairie dog activity was observed in the draw. <br />Prairie Dog Complex <br />Much of this old prairie dog town is inactive. Some holes had collapsed or had been filled and <br />only a few were active. Vegetation in the area was dominated by low growing herbaceous species <br />such as flixweed, blue mustard, fillaree, and prickly pear cactus. <br />Bare Ground <br />There are patches of land void of vegetation scattered throughout the Expansion Area North. One <br />hill on the south edge of the pond was also unvegetated. This vegetative community also includes <br />the roads throughout the area. The northern part of the Expansion Area South is also baze ground. <br />This is from frequent motor vehicle use. <br />Water <br />Approximately 3.6 acres of the 21-acre Expansion Area North is currently classified as water. <br />This gravel pit lake was created by historic mining activity. <br />Threatened and Endangered Plant Species <br />The United States Fish and Wildlife Service (USFWS) has published a list of threatened and <br />endangered plant species occurring by county in Colorado, including species that occur in Adams <br />County (USFWS 2004). This list was consulted prior to conducting the field survey to determine <br />which species might be present within the Expansion Area. Table J-I lists the threatened, <br />endangered, and candidate plant species listed by the USFWS for Adams County (USFWS 2004). <br />Table J-1 Threatened, Endangered, and Candidate Plant Species in Adams County <br />Common Name ScientiSc Name Federal Status <br />Colorado butterfly plant Guara neomexicana ssp. <br />coloradensis Threatened <br />Ute ladies'-tresses S iranthes diluvialis Threatened <br />Source: USFWS Ecological Services, Colorado Field Office August 16, 2004. <br />189g-Frei 112 Euhibits_(4.20.05),doc J-4 <br />
