COIO~ f0 <br />University <br />June 12, 2002 <br />Scott Keen <br />4814 South Pine Road <br />Evergreen, CO 80439 <br />Dear Mr. Keen: <br />Know/edge to Go Places <br />Colorado Natural Heritage Program <br />College of Fatural Resources <br />254 General Services <br />Fort Collins, Colorado 80523-6021 <br />(970)491-1309 <br />FdX: (970) 491-3349 <br />w~»~u-.cnhp.colostate.edu <br />The Colorado Natural Heritage Progam (CNHP) is in receipt of your request for infomlation regazding <br />the proposed gravel mining project area. In response, I have searched our Biological and Conservation <br />Datasystem (BCD) for natural heritage elements (occurrences of significant natural communities and raze, <br />threatened or endangered plants and animals) documented from the vicinity of the azea specified in your <br />request, specifically most of the SW '/o of the SW '/4 of Section 35, Township 1, Range 67 W in Adams <br />County. <br />The enclosed report describes natural heritage resources known from this area and gives location (by <br />Township, Range, and Section), precision information, and the date of last observation of the element at <br />that location. This report includes elements known to occur within the specified project site, as well as <br />elements known from similar landscapes near the site. Please note that "precision" reflects the resolution <br />of original data. For example, an herbarium record from "4 miles east of Colorado Springs" provides <br />much less spatial information than a topographic map showing the exact location of the occurrence. <br />"Precision" codes of Seconds, Minutes, and General aze defined in the footer of the enclosed report. <br />The report also outlines the status of known elements. W e have included status according to Natural <br />Heritage Program methodology and legal status under state and federal statutes. Natural Heritage ranks <br />are standardized across the Heritage Progrmn network, and are assigned for global and state levels of <br />rarity. They range from "1" for critically imperiled or extremely rare elements, to "5" for those that are <br />demonstrably secure. <br />You may notice that some occurrences do not have sections. Those species have been designated as <br />"sensitive" due to their rarity and threats by human activity. Peregrine falcons, for example, are <br />susceptible to human breeders removing falcon eggs from their nests. For these species, CNHP does not <br />normally provide location information beyond township and range. Please contact us should you requee <br />more detailed information for sensitive occurences. <br />There is one CNHP designated Potential Conservation Areas located within the vicinity of your project <br />area (see enclosed map). 1n order to successfully protect populations or occurrences, it is necessary to <br />delineate conservation areas. These conservation areas focus on capturing the ecological processes that <br />are necessary to support the continued existence of a particular element of natura[ heritage significance. <br />Conservation azeas may include a single occurrence of a raze element or a suite of rare elements or <br />significant features. <br />'~~Sa`~{eritaBe m <br />'' - ~ <br />~IORP~ <br />
