Other plant species present on the site included the grasses western wheatgrass (Pascopyrum <br />smithii), blue grama (Bouteloua gracilis), and Indian ricegrass (Achnatherum hymenoides). Al- <br />so present were wirelettuce (Stephanomeria tenuifolia) and buckwheat (Eriogonum deflexum. <br />Not seen in 2013, although observed in 2012 were bottlebrush grass (Hordeum jubatum) and <br />winterfat (Krascheninnikovia lanata). Some plants, particularly the grasses, were clipped, pre- <br />sumably from grazing by cattle and wildlife. <br />Wildlife <br />Wildlife observations included two coyote, passerine birds, raven, and lizard. Animal sign in- <br />cluded owl (feathers, pellet, and whitewash), pronghorn (tracks), rabbit (pellets and tracks), ro- <br />dent (burrows), and domestic cow (dung and tracks). <br />5.0 NOXIOUS WEEDS <br />No Colorado state - listed noxious weeds were observed during the 2013 site monitoring. Colo- <br />rado Noxious Weed List is divided into a List A, B, C and Watch List based on control require- <br />ments as designated by the Commissioner and other entities (http: / /www.colorado.gov /cs <br />/Satellite /ag Conservation /CBON/1251618874438). List A species are designated for eradica- <br />tion (22 species statewide). List B weed species have state noxious weed management plans <br />designed to stop the continued spread of these species (37 species statewide). For List C weed <br />species, local governing bodies facilitate more effective integrated weed management on pri- <br />vate and public lands with management plans designed to provide additional education, re- <br />search, and biological control resources to jurisdictions that choose to require management of <br />List C species (15 species statewide). Watch List weed species pose a potential threat to the <br />agricultural productivity and environmental values of the lands of the state. The Watch List is <br />intended to serve advisory and educational purposes only (22 species statewide). <br />Costilla County lists nine noxious weed species (eight from the List B and one from List C) as <br />presented in Table 3. Previously two patches of noxious weeds near the mine entrance were <br />present during 2005 to 2011. These noxious weeds patches were comprised of Canada thistle <br />and Russian knapweed. These patches of noxious weeds appear to have been eradicated and <br />no additional plants were noted. A non - native species, Russian thistle (a.k.a. tumbleweed; <br />Salsola kah), is present in low numbers in some of the areas of the reclamation site. However, <br />4 <br />
