proximity ofthe Bernhardt resource site to the site where the mouse was trapped, the U.S. <br />Fish and Wildlife Service has indicated that a trapping survey is not necessary for the <br />Bernhazdt resource site. They consider the Bernhardt resource site to be within the <br />dispersion corridor and range of this mouse population. Therefore, U.S. Fish and <br />Wildlife Service will require a mouse mitigation plan be prepazed and submitted for the <br />Bernhardt resource site. <br />Potential habitat for the Ute ladies'-tresses orchid is present along the Big Thompson <br />River primary alluvial floodplain that includes riverbanks and oxbows south of the river. <br />Habitat is also present within other depressions and swales on the site. A pedestrian <br />survey for the orchid was conducted August 2, 2002 during the normal blooming period. <br />No orchids were encountered within the project site. The U.S. Fish and Wildlife Service <br />concurred with the results of the survey. <br />No eagles or nests were observed during our investigation of the site. Based on our on- <br />site investigation, the cottonwood trees throughout the ripazian comdor aze mature and <br />some are senescent. It has been our observation that the majority of ripazian corridors <br />along the Front Range of Colorado consist primazily of mature cottonwood trees with <br />little or no recruitment. This being the case, there will come a time when the mature <br />cottonwood trees aze gone and the overstory structure of the ripazian corridor will be lost. <br />Reclamation within the permit azea and cottonwood ripazian corridor could, in the long <br />term, be of great benefit in maintaining the riparian corridor. Planting cottonwoods of <br />varying ages throughout the riparian comdor as part of the reclamation would provide <br />replacement trees for the mature cottonwoods, and enhance the overall existing ripazian <br />corridor habitat. <br />Project Effects to R'ildlije <br />According to the proposed mineral extraction plan for the Bernhardt resource a large <br />portion of the riparian corridor that includes the majority of the mature cottonwood trees <br />and understory adjacent to the river will be undisturbed. Noise and air emissions during <br />mining will cause a temporary disturbance to wildlife. Species such as raccoons, coyotes, <br />beaver, deer, and raptors will continue to use the ripazian corridor during mining <br />operations and the site itself when operations aze not active. Bird species will use the <br />periphery of the site and the site itself opportunistically, if prey or food species are <br />present. <br />The proposed project will extract material and leave cells within the site. Permanent <br />reclamation of the site will entail grading, respreading topsoil, and seeding and planting <br />perennial species that will support wildlife species. The mining and reclamation will <br />create a more diverse habitat than is currently present. Areas of open water will sustain <br />additional species of reptiles and amphibians as well as shorebirds and waterfowl. The <br />addition of the water will create fringe environments favorable to predatory mammals <br />and raptors, as well as food and water sources for herbivores. With the planting of <br />additional cottonwood trees and shrubs, additional strata and vegetation layers will be <br />
