Les passages fauniques

Wildlife needs to move through its habitat to eat, drink and reproduce. When a road is built in the middle of a habitat, wildlife must cross it. Biologist Emilie Brien is a natural area manager for the Nature Conservancy of Canada. She manages a citizen science project on Highway 3 in the Crowsnest Pass in the Rockies, on the border of Alberta and British Columbia. The busy highway is a barrier to the north-south movement of wildlife.
