From a distance, the grey cement bridge looks unremarkable. Two tunnels on either side of the Trans-Canada Highway are in semi-circles that end bluntly on the pavement below. But on top, away from passing motorists’ eyes, lies a grassy oasis. Against the odds, pine trees and wildflowers have taken root here, giving the overpass a fringe of greenery. On the edges, wire fencing provides safe passage for wandering animals.
Tony Clevenger has dedicated much of his life to studying the performance of Banff’s wildlife crossing structures. When the first wildlife bridges went up, Clevenger, a researcher with the Western Transportation Institute, was living in Canmore, and recalls the distinctly negative atmosphere that surrounded what many saw as a hair-brained scheme by Parks Canada. Save for a few small crossings in the eastern United States, no one had ever attempted something like this before — and no one believed it would work. Editorials in the local paper scoffed at the “waste of taxpayers’ money” and confidently stated animals would never use the $2 million to $3 million man-made bridges. Others believed wolves would herd their prey into the fence, violently killing them before shocked tourists.
“This project started in a bad spot. There was a lot of opposition and criticism,” Clevenger says. “It took several years of good data, publishing in scientific peer-reviewed journals, to change people’s minds.”
Clevenger now has 17 years-worth of data proving the efficacy of the crossings. Among large carnivores, mortality (死亡) rates are 50 to 100 per cent lower along sections of the highway where overpasses and underpasses exist. In those same sections, mortality rates for elk are almost zero, compared to 100 elk-vehicle collisions per year in the mid-1990s. Clevenger’s research has shown that 11 species of large mammals in Banff have used the structures more than 200,000 times, including unexpected species such as red fox, hoary marmot, boreal toads, wolverines, lynx, garter snakes and beavers.
In 2014, a Montana State University study found that not only are grizzly bears using the crossing structures, but the structures are also helping to maintain genetically healthy populations among the bears that use them. Grizzlies were crossing with enough frequency to ensure populations on either side of the highway weren’t genetically isolated from each other.
“This is Canada’s biggest conservation success story — it’s the largest highway mitigation complex in the world,” says Clevenger. “You won’t find anything anywhere else in the world close to what we have. We have the most overpasses in one localized area and almost half of all the overpasses in North America.”
