Mathews Division of Minersis a uc~~CgY <br />Division of Mineral and Geology, Room 215 <br />1313 Sherman Street <br />Denver, CO 80203 <br />Dear Dan: <br />The Colorado Natural Heritage Program (CNHP) is in receipt of your request for information regarding <br />the Deserado Mme project. In response, CNHP nas searched its tsiolugical and Conservation Datasystem <br />(BCD) for namral heritage resources (occurrences of significant natural communities and rare, threatened <br />or endangered plants and animals) documented from the immediate area of Rio Blanco County, Cactus <br />Reservoir Quadrangle. <br />We have enclosed two reports from BCD. Ore describes natural heritage resources known frotr: the area <br />and gives location (by "township, Range, and Section), precision of the locational infonmation, and [he <br />date of last observation at that location. Please note that "precision" retlects the resolution of original <br />data. For example, an herbarium record from "4 miles east of Coiorado Springs" provides much less <br />spatial information than a topographic map showing the exacr location of the occurrence. "Precision" <br />cedes o`Seconds, Minutes, and General are defined in the report footer. <br />You may notice that some occurrences do no[ have sections listed. Those species have been designated as <br />"sensitive" due to their rarity and threats by humans. Peregrine tal:;uns, for example. are susceptible to <br />human breeders removing falcon eggs from [hair nests. For these species, CNIiP does not provide <br />locational information beyond township and range. Please contact us should you require more detailed <br />information for sensitive occurrences. <br />A second report outlines the status of the known elements. We have included status according to Nattirai <br />Heritage Program methodology and legal status under state and federal statutes. Natural feritage ranks <br />are standardized across the Heritage Program network, and are assigned for global and state levels of <br />rarity. They range from "l" for critically imperiled or extremely rare elements, to "5" for those that are <br />demonstrably;ecure. For your com•enience we have also included'nabitat descriptions. However, please <br />be aware that these descriptions are in draft form and have not been edited for content. Please do not cite <br />CNHP habitat information; instead, cite the original source of the habitat information as indicated. <br />The Colorado Division of Wildlife has legal authority over wildlife in the state. CDOW would therefore <br />be responsible for the evaluation of and final decisions regarding any potential effects a proposed project <br />may have olt wildlife. If you would like more specific information regarding these or other vertebrate <br />species in the vicinity of the area of interest, please contact the Colorado Division of Wildlife. <br />The information contained herein represents the results of a search of Colorado Natural Heritage <br />Program's (CNHP) Biological and Conservation Data System (BCD).
