This monthly trend correlates closely with the movement of deer on the wintering area, which is determined by weather conditions and food preferences. Present at the higher elevations of the winter range and accessible to the tier during the early part of the winter are such browses as cuiv leaf mountain mahogany, snowbrush, greenleaf manzanita, and squaw carpet. These plants contribute most heavily to the diet from October through December, and of these plants, squaw carpet is apparently a preferred forage. Deer are known to seek- ou1 this plant even when it is covered by snow. The consumption of bitterbrush exhibits a definite seasonal utiliza- tion. As seen in Table 3, bitterbrush made up percent by volume of the October diet and was found in 100 percent of the stomachs, but by January and .March the consumption of bitterbrush decreased to a point where it contributed little to the diet. As bitterbrush use falls off in the late winter months, sagebrush takes its place as the staple browse in the diet. There was but one occurrence of sagebrush in the October stomachs and little sagebrush was eaten in November. Beginning in December, the consumption of sagebrush in- creased appreciably. It made up percent of the December diet and was found in (i.'!.(i percent of the stomachs; by January and February it constituted and percent, respectively, of the diet. This heavy consumption of sagebrush continued in March, bul decreased noticeably in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability
