Over the long term, mountain caribou (Rangifer tarandus caribou) conservation will almost certainly require the maintenance of connectivity among herds, but the characteristics of what constitutes connecting habitat are neither obvious nor easily determined. We felt that GPS (global positioning system) radio-collars might provide the frequency of location data required to detail caribou travel paths, and that those data might provide some indication of what might constitute caribou movement corridors.
