C'~lo~~~o Urrlversiry June 12, 2002 Scott Keen 4814 South Pine Road Evergreen, CO 80439 Dear Mr. Keen: Xnowledge to Go Places Colorado Natural Heritage Program College of Natural Resources 254 General Sen~ces Fort Collins. Colorado 60523-6021 (970)491-7309 FAX: (910) 491-3349 www.cnhp.colostate.edu The Colorado Natural Heritage Progam (CNHP) is in receipt ofyour request for information regazding the proposed gravel mining project area. lA response, I have seazched our Biological and Conservation Datasystem (BCD) for natural heritage elements (occurrences of significant natural communities and rare, threatened or endangered plants and animals) documented from the vicinity of the azea specified in your request, specifically most of the S W '/< of the S W '/. of Section 35, Township 1, Range 67 W in Adams County. The enclosed report describes natural heritage resources known from this area and gives location (by Township, Range, and Section), precision information, and the date of last observation of the element at that location. This report includes elements known to occur within the specified project site, as well as elements known from similar landscapes near the site. Please note that "precision" reflects the resolution of original data For example, an herbarium record from "4 miles east of Colorado Springs" provides much less spatial information than a topographic map showing the exact location of the occurrence. "Precision" codes of Sewnds, Minutes, and General aze defined in the footer of the enclosed report. The report also outlines the status of known elements. We have included status according to Natural Heritage Program methodology and legal status under state and federal statutes. Natural Heritage ranks are standazdized across the Heritage Program network, and are assigned for global and state levels of rarity. They range from "I" for critically imperiled or extremely raze elements, to "5" for those that are demonstrably secure. You may notice that some occurrences do not have sections. Those species have been designated as "sensitive" due to then rarity and threats by human adiviry. Peregrine falcons, for example, are susceptible to human breeders removing falcon eggs from their nests. For these species, CNHP does not normally provide location information beyond township and range. Please contact us should you require more detailed information for sensitive occurrences. There is one CNHP designated Potential Conservation Areas located within the viculiry of your project azea (see enclosed map). In order to successfully protect populations or occurrences, it is necessary to delineate conservation areas. These conservation azeas focus on capturing the ecological processes that are necessary to support the continued existence of a particular element of natural heritage significance. Conservation azeas may include a single occurrence of a raze element or a suite of raze elements or significant features. P` x¢rftgBe~ a`yt '> ~ ~tORA1~
