The movements and habitat use of radio-collared caribou within the 80,000 hectare "migration corridor" between Tweedsmuir Park and the primary winter range were examined from spring 1993 through spring 1995. In the relatively mild winter of 1993/94, about half the animals used the study area for most of the winter. When used for wintering, caribou favoured older forest on poor tree growing sites (generally good lichen sites), and wetland/forest mosaics. During spring and fall migration movements, habitat use is less distinct.
A management strategy is proposed consisting of:
1) maintaining amounts of mature forest similar to that expected under long-term natural disturbance regimes,
2) directing timber harvest primarily to areas of lower value to caribou,
3) access control, and
4) innovative silvicultural practices.
