Protecting pronghorn migration routes is a big deal in Wyoming. The same goes for mule deer. But making sure the animals have unimpeded routes between their summer and winter ranges is only part of the puzzle. Recent research shows that it’s even more important to protect the places where the animals stop along the way. I spoke with Matt Kauffman, who heads the Wyoming Cooperative Fish and Wildlife Research Unit, to find out more about the studies that have been done. Kauffman says he and his colleague Hall Sawyer discovered some surprising things about mule deer migration.
