Yellowhead (BMA 3) Grizzly Bear Population Inventory

This project uses DNA from hair snags to create a population inventory of grizzly bears in BMA 3 and Jasper National Park.

This project began in the Pembina area, but expanded as new partners, such as West Fraser, Parks Canada, and the government of Alberta joined the effort.

Over 250 hair snag sites were set up across the Yellowhead region, often in very remote areas. The result is the first repeat estimate of grizzly bear populations in Alberta.
