WTI Research Scientist Tony Clevenger was interviewed by WHYY radio in Canada regarding his 17-year research project to evaluate the wildlife crossing structures in Banff National Park.  The discussion highlighted the research techniques used to determine which animals were using the crossing structures; these techniques included animal tracks, hair traps, and remote wildlife cameras. The entire audio interview is available on the WHYY website. The online article also features photos of a fox, wolf, elk, linx and bear using the wildlife crossings, and a video clip of a bear and two cubs on one of the structures.
