Exhibit) <br />• Penrose-Rock outczop complex, 25 to 65 percent slopes, occurs on some of the outer <br />edges of the project area. The native vegetation is mainly plains grasses, yucca, bigelow <br />sagebrush, juniper and skunkbush: The potential production of the native understory <br />vegetation in normal yeazs is about 500 pounds of air-dry vegetation per acre. These. <br />complexes are discussed further in Exhibit I. <br />SPECIES OF SPECIAL CONCERN <br />No specific surveys for threatened, endangered, or special-concern species are proposed <br />at this time. Information indicates no known populations of threatened, endangered, or <br />special-concern species or critical habitat aze located within the study area. Data sources <br />include, but are not limited to, contacts with the USFWS, CDOW, Colorado Natural <br />Heritage Program, and additional published literature. If data indicate to the contrary, <br />specific surveys will be proposed at that time. <br />RECLAMATION <br />The reclamation objective for the project azea is for shortgrass prairielrangeland. Keeping <br />disturbance to a minimum and controlling the noxious weeds will be necessary. <br />Prevention of erosion is also necessary. Reseeding with native species that occur on or in <br />the vicinity of the site will help to control alien species. Long-term diligent management . <br />of noxious weeds can be accomplished by a combination of biological, chemical, <br />cultural, and physical methods at the site (CNAP 1998). A grass seed mixture will be <br />• approved by the Pueblo County Extension Office. <br />REFERENCES <br />Colorado Natural Areas Program (CNAP). Native Plant Revegetation Guide for <br />Colorado.
