Biologist Lorne Fitch of Alberta Environment has some practical advice about how to salvage a damaged waterway.
The goal is to create deep, U- shaped channels that look like cupped hands, he says. From a shallow trickle, they could achieve a depth of as much as 2.5 metres.
As creeks and rivers are restored, the water table rises and the green strip of trees and grasses becomes wider and healthier.
Then, landowners usually notice wildlife returning, said Fitch. Species of birds and small animals that had all but disappeared now are seen frequently in these restored areas.
Studies show more birds like yellow warblers, cedar waxwings, robins, flycatchers, wrens and morning doves are returning.
