Fragile Nature

Highways may not seem like a big imposition on habitat, but they often isolate populations from one another, the first step toward extinction. This wildlife overpass near Banff National Park, combined with fencing that leads animals to it, is designed to give wildlife a way to cross over the interstate. It is now thought that underpasses work better for skittish animals too shy to cross out in the open. (Image ID: BEA014-00001)
