Demography of Noatak grizzly bears in relation to human exploitation and mining development
Ballard WB. 1987. Demography of Noatak grizzly bears in relation to human exploitation and mining development. Natural Resources Survey and Inventory Report. AR 87/03. Alaska Department of Fish and Game, Division of Game. Juneau, AK
This progress report by the Alaska Dept. of Fish and Game in cooperation with the U.S. National Park Service is the initial report in a series on grizzly bears in and adjacent to Noatak National Preserve. This study was begun in 1986 to determine the effects of human harvests and gather baseline data on the grizzly bear population prior to major mining development at Red Dog Mine. Forty-seven grizzly bears were captured in late May and early June 1986; 31 were radio-collared. Radio-collared bears were relocated on 278 occasions during 1986. Generally, bears remained in the mountains or foothills through July. In early August, some moved to stream bottoms to forage on fish before returning later in the year to higher elevations for denning. An attached appendix lays out in detail a proposed study plan for future grizzly bear research in the area.
