Tlie primary feeding grounds luentioned above support the Eriogonum fa- scicuIafum-Stipa spcciosa vegetation described by Buechner. Conniion associates on these decomposed granite soils include bitterbrush {Pur- sJiia tridcntata or gJanduloso), green ('])h('di'a (Ephfdra riridis), big sagebrush {Artemisia tri/lcntaia), rabl)itl)rusli (Clirysothamnvs viscidi- flonis), and low-growing perennial forbs {Eringonum spp.). Common in rock outcroppings are Haplopappus cuneatus and Penstemon brevi- florus. Grasses otlier tlian Stipa are S(juii'rel1ail (Sitrniion ), occasionally^ ricegrass {Onjzopsis hymenoidcsj, and in good rainfall years redbrome {Bromns ruhens) and eheatgrass (Broiuiis tectorum). Composition of Bighorn Populations One hundred eighty-lwo siglitiii^s of Sierra bigli(»rji sheep Avere made in tlie study (Table 1). However, part of these were repeats, particu- larly ill ])lack and SaAvmill Canyons. Group size ranged from 1 to 18 with a mean of The observed sex ratio of 81 rams to 100 ewes is not reliable since the large rams remain segregated from the ewes for the most part, and occupy more inaccessible country. Also, the rams are considerably more warv than tlie FIGURE 3. Two prime rams, two young rams, two ewes, and a lamb on o feeding ground on a bench just north of the mouth of Black Canyon. This is the gentlest terrain in which sheep were observed regularly. Note the escape terrain in the near background. Photograph by Dale R.
