Researchers have traced a sharp decline in survival of caribou calves to climatic warming.
When roads, logging, oil drilling, power lines or even tourist resorts move into caribou range, the sensitive animals move out.
Field research now confirms what anecdotal evidence previously suggested: snowmobiling causes mountain caribou to abandon high-quality winter habitat.
Several subpopulations of mountain caribou in British Columbia, including three with fewer than seven individuals in 2002, face imminent extinction.
Close monitoring of 50 newborn woodland caribou calves for their first two months of life provides some insights into caribou behaviour and the factors that influence calf survival.
Mountain caribou do not always return to the same forested site each winter.
Mapping the landscape features preferred or avoided by mountain caribou reveals almost no high quality terrain remains for these endangered ungulates south of the Trans-Canada Highway in British Columbia.
Researchers plugging expert consensus about caribou ecology into a Bayesian network model have come up with a transparent decision-making tool to help maintain woodland caribou habitat.
