But the city is growing — from 600,000 people in 1990 to nearly 900,000 today — and that’s pushing development and transportation infrastructure up against this riverine system. Habitats are being reduced in size and fragmented by roads, creating many risks for the river valley’s wildlife.

Recognizing the threat urban development posed for the river ecosystem, Edmonton embarked on an ambitious effort to accommodate growth while at the same time protecting wildlife and habitat. In 2007, the city built its first wildlife passage — a culvert that allows small mammals to pass between two sections of ravine that had been cut up by a road. More were soon planned.
