Information on grizzly bear (Ursus arctos horribilis) distribution and relative seasonal abundance in the Bridger-Teton National Forest, Wyoming, was gathered by direct observation of bears and bear sign and by outfitter interviews in 1977-78. Operation of commercial outfitting camps was examined and case histories of bear-human interactions documented in 1978 to assess the potential for bear-human conflict. We compiled 394 reports of grizzly bear for 1968-78, including 228 reports for 1977-78. Report localities were distributed widely throughout the northern portion of the Forest, but concentrated in Teton Wilderness (Buffalo Ranger District). An estimated 45 grizzlies occurred on the Forest during May-November 1977: 15 single bears and 10 females with 20 young. In 1978, 37-38 grizzly bears were tallied during May-November: 21-22 single bears and 7 females with 9 young. Each of 20 outfitter camps examined had conspicuous bear attractants, including low-hanging racks of game meat, open garbage pits, and unsealed livestock and human foods. Attractants were near human quarters and concealment cover for bears. Eighteen camps had histories of bear encounters. Management guidelines could reduce attraction of camps for bears.
