MANAGEMENT OF CHAMISE BRUSHLANDS 469

FIGURE 10. Very heavy browsing by deer the first year after burning killed most of the sprouts, but seedlings survived and will continue to furnish browse. Grassy spots in brush furnish valuable forage for deer In late winter and early spring when the herbage is green and succulent. The extent to which deer and sheep may suppress sprout growth is indicated by measurements of chamise sprouts under various conditions of grazing use and in protected areas on two-year-old burns (Figure 11). Even light browsing by deer considerably suppresses the growth of sprouts. A majority of the sprouts browsed lightly by deer averaged about 18 inches in height while those protected by fenced exclosures averaged between 22 and 32 inches. Hea\y utilization from year to year will continue to suppress sprout growth (Figure 12). A majority of plants browsed heavily for five years averaged only 17 inches in height while plants protected from browsing averaged between 22 and 32 inches in only two years. Sprouts protected entirely from browsing for five years were not available for comparison. Close utilization bv deer mav kill manv of the sprouts the first vear following fire. This results in opening the brush. Some sprouts may be killed the second year, but few, if any. are killed after the sprouts are five years or more old. After the chamise plants are six to eight inches tall the stiff stems prevent the deer from grazing so close as to kill the plants. On a seven-year-old burn no plants of chamise were killed by hea^'y browsing in the past two years. In August, 1948, about 25 acres of old brush burned along with some 300 acres that had burned in 1945. This area supported an estimated 100
