Movements of the Denali Caribou Herd

Troyer W. 1981. Movements of the Denali Caribou Herd. US National Park Service. Alaska Regional Office. Anchorage, AK

(Adapted from author's abstract.) This is an unpublished U.S. National Park Service completion report of movement studies of the Denali Caribou Herd from May 1976 through December 1979. Radio transmitters were used to document caribou movements, with 13 caribou radio-collared in 1976, 7 in 1977, and 8 in 1978. During this study, caribou calved in three major areas: the Cantwell calving grounds, Stampede calving grounds, and Wonder Lake calving grounds. Of the 28 caribou radio-collared, 21 were tracked from 6 to 48 months and their individual movements documented. The remaining 7 either died or their radios malfunctioned. Significantly, many individual caribou changed their wintering area several times, indicating that caribou wintering in two different regions are not a discrete population. Some caribou returned to the same wintering area for all three years but others switched wintering areas one or more times.
