Habitat use and behavior of grizzly bears (Ursus arctos) were studied in 3 areas of the Arctic National Wildlife Refuge, northeast Alaska, during 1982 and 1983. Scanning for bears resulted in 386 and 388 h of behavioral and habitat use information. Vegetation on 3,626 ha in the Caribou Pass-Kongakut River study area was mapped to Viereck-Dyrness (1980) level IV. Grizzly bears devoted most of their nonhibernating time to feeding and foraging. Food habits and habitat use were influenced by the phenological development of herbaceous plants and berry-producing plants and availability of animal food items.
