Historical Roots For Wildlife Crossings

Wildlife crossing have been around for a little while now. In the 1980s, the Canadian Banff National Parks set up standard North American wildlife crossings making or constructing 22 underpasses and two overpasses where the highway bisects the parks. Other research shows that grizzlies, wolves, elk, and other animals have used the wildlife crossings about 240,000 times which resulting in a 80% percent decline in collisions with cars. Other researchers also have documented mothers teaching their young (babies) how to negotiate different routes to take. The impacted of bigger animals cause more damage to vehicles than smaller animals such as rabbits and foxes.
