Some of these MS3 areas lie within the areas considered as SMAs in the alternatives (, Baker's Hole campground). The grizzly bear population has increased in recent years (Knight and Blanchard 1995).. General Grizzly Bear Food Habits. Food habits of grizzly bears in the Yellowstone area vary greatly from year to year depending on availability of preferred foods. Although some bears depended heavily on garbage in the interior of the park prior to 1969-70, they shifted their diets to other foods when the dumps were closed in 1969-70 (Craighead, Sumner, and Mitchell 1995). Craighead, Sumner, and Mitchell (1995) suggest that bears may have increased their annual range sizes to compensate for loss of garbage food sources. They also suggest that the bear population decreased and bears redistributed themselves away from the Central Plateau and moved toward the park peripheries following the closing of the dumps. Researchers relate reduced litter sizes in grizzly bears to the loss of garbage in the diet. Human-caused mortality of grizzly bears increased after the dumps were closed (Craighead et al. 1995), and the grizzly bear population is reported to have declined from 1967 through 1980 (Craighead, Varney, and Craighead, Jr. 1974; Knight and Eberhardt 1985). By the mid-1980s, human-caused mortality of adult female grizzly bears had decreased and began to allow the grizzly bear population to increase again (Fberhardt and Knight 1996).
