Laura Tepper: Road Ecology: Wildlife Habitat and Highway Design



The iconic wildlife overpasses along the Trans-Canada Highway in Banff National Park facilitate wildlife movement and protect animals and vehicles from colliding. Six landscaped bridges, each 180 to 200 feet wide, extend habitat across the highway in strategic locations identified by researchers overlaying data about wildlife-vehicle collisions and animal migration patterns. They feature natural elements from the surrounding ecosystems, including immature spruce-pine forest favored by bears and sticks and scree preferred by amphibians and small mammals. Humans (except researchers) are banned from the crossings. Click image to enlarge. [All photos by Laura Tepper except as noted.]
