• The pinon-juniper understory species composition follows: <br />Cheatgrass 6% <br />Indian rice grass 6% <br />Squirreltail 3% <br />Mormon tea 13% <br />Mountain mahogany 3% <br />Big sagebrush 29% <br />Serviceberry 35% <br />Total Species Composition 100% <br />The pinon-juniper overstory cover from the preliminary <br />evaluation was determined to be 12.0 %, while the understory <br />cover was 26.0%. Woody plant density of the overstory was <br />1.0 plant per 100 ft transect. The understory woody plant <br />density was 9.0 plants per 100 ft transect. <br />The preliminary pinon-juniper production value was 800 lbs <br />per acre during favorable years with 650 ibs per acre in <br />unfavorable years. The median production was determined to <br />be approximately 725 ibs per acre. Approximately 40% of <br />this production is unpalatable or unavailable to grazing <br />animals. <br />• The preliminary species composition of the big sagebrush <br />community follows: <br />Squirreltail 2Y. <br />Needle-and-thread 4% <br />Indian rice grass 2% <br />Intermediate wheatgrasa 1% <br />Cheatgrass 41% <br />Cactus 1% <br />Forbs 1% <br />Sagebrush 4T/. <br />Winterfat 1% <br />Total Speeies Composition 100% <br />Preliminary cover for the big sagebrush community was <br />determined to be 33.0%. The woody plant density was 9.0 <br />plants per 100 ft transect. The preliminary production <br />values were 1,000 lba per acre in favorable Years, with 850 <br />lbs per acre during unfavorable years. The median <br />production is approximately 950 lbs per acre air dried. <br /> <br />78 <br />Revised 5/87 <br />
