,, <br />Section 816.97(d) Continued. <br />779.20, the primary forage requirements of the three most important <br />wildlife species are summer forage for antelope and deer, and <br />winter forage for sage grouse. Stoddard and Smith (1955) report <br />that the dietary requirement of antelope "is composed largely of <br />browse...". Deer are reported to prefer forbs and browse. The <br />Institute for Land Rehabilitation (1978) also report that summer <br />foods of antelope and deer are dominated by browse. Sage grouse <br />are reported to be largely dependent upon sagebrush for food and <br />cover. <br />Required Plant Species For Habitat Restoration <br />Summer forage habits of southern Wyoming antelope are reported by <br />preference to be douglas rabbitbrush and big sagebrush (Severson <br />et. al. 1968:20), Intake of forage in this study was found to be <br />1.5 pounds of air dry forage per day. Consumption of douglas <br />rabbitbrush was 86 percent of the intake and big sagebrush 12 <br />percent. The USDA, SCS (1976) reports that one mature antelope is <br />equal to 0.20 animal units. <br />Spring forage consumption by mule deer in Colorado was reported to <br />be 12 percent browse, 82 percent forbs, and 6 percent grass. <br />Summer forage consumption by mule deer is reported by Hansen and <br />Reid (1975) to be 10 percent shrubs, 48 percent forbs, and 42 <br />percent grasses. Fall forage consumption was reported to be 6 <br />percent browse, 85 percent forbs and 9 percent grasses. USDA, SCS <br />(1976) report that a mature mule deer is the equivalent of 0.20 <br />animal units. <br />Sage grouse dietary intake in North Park (Rogers 1964: 29-31) was <br />found to be almost exclusively sagebrush from September to Apr11, <br />with increased insect and forb consumption during the summer months. <br />Barber and Nagg (1969) found that the daily consumption of forage <br />by sage grouse was 200 grams per day. <br />816-119 <br />
