A new study confirms woodland caribou in Alberta are declining at a faster pace than anywhere else in Canada.

The data was published recently in the Canadian Journal of Zoology and shows woodland caribou are declining so quickly that their populations are being cut in half every 8 years.

Concern came to a head earlier this year after a Canadian Press investigation revealed the province had sold industrial leases on nearly all of the last tiny bit of undisturbed habitat in northwestern Alberta.

Environmentalists want to know why the area, which both levels of government have promised to protect, is being hammered by development.
