Major ecological changes are afoot in western Canada's boreal forests, and they have scientists concerned. The most glaring problem is a steep decline in boreal woodland caribou (Rangifer tarandus caribou), listed as threatened under Canada's Species at Risk Act.
"There are populations in Alberta that probably don't have a couple years to live," says wildlife ecologist Jason Fisher of the University of Victoria. "It's bad. This is really something we have to address immediately."
