Ray Mountains Caribou: Population Distribution 1994-1997

Preliminary findings of habitat use patterns for the Ray Mountains caribou (Rangifer tarandus) herd were determined from three years of radiotelemetry observations. Caribou calving was concentrated in open south-sloping plateaus between Mt. Tozi and the Tozitna River. Most of the herd wintered between the Ray Mountains and the Kanuti-Kilolitna river. Use of previously designated Areas of Critical Environmental Concern was examined. Fire history of the caribou range was compiled with caribou locations to determine whether burned areas were used. There was minimal overlap between fire locations and caribou locations.
