Mechanisms underlying the decline of mountain caribou (Rangifer tarandus caribou) in British Columbia ...
The distribution and abundance of mountain caribou (Rangifer tarandus caribou) in British Columbia has declined. High predation rates as a consequence of forest management and associated changes to the relative abundances of alternate ungulate prey species have been proposed to cause the population...

The distribution and abundance of mountain caribou (Rangifer tarandus caribou) in British Columbia has declined.

A direct link between changes in the forest age structure and declining caribou population trends, however, is lacking. Understanding the underlying mechanism of the population decline is necessary to develop recovery strategies aimed at maintaining a viable mountain caribou population.
