Detailed explanation-1: -For over 20 years now, the solution in Banff National Park has been its wildlife crossings, several dozen bridges that help animals cross the Trans-Canada Highway. The idea first came about in 1978.
Detailed explanation-2: -From its humble beginnings, the Banff Wildlife Crossings Project has grown to include 38 underpasses and six overpasses, spanning from Banff National Park to the British Columbia border.
Detailed explanation-3: -The most common forms of wildlife crossing are bridges and overpasses, tunnels, viaducts and culverts. Features of this kind are increasingly included in highway planning and road improvement schemes.
Detailed explanation-4: -Ultimately, the research provided evidence, for the first time, that the crossing structures enabled otherwise isolated bear populations on either side of the highway to breed. Animals weren’t just using the crossings-they were relying on them to prevent genetic isolation.
Detailed explanation-5: -This includes (but is not limited to): topography, road dimensions, vegetation, exposure and climatic conditions of the site, as well as the proper location of a planned crossing including impacts from human development, disturbance, and adjacent land use.
