New map illustrates caribou decline in Canada
Caribou populations are dropping all across Canada, with one herd — the South Selkirk — in British Columbia down to just three females by April 2018. Caribou (Rangifer tarandus) herds are complex in Canada, with some migrating across vast northern territories and others staying put in relatively smaller ranges. Many of these overlap as well. But while the state of other herds isn’t quite as dire as the South Selkirk herd in British Columbia, many are still considered endangered by the Committee on the Status of Endangered Wildlife in Canada. In an effort to illustrate the situation of these different herds, Canadian Geographic created a map that shows how each herd has declined compared to their largest estimated population.
