Trappers assist biologists with Wolverine ecology insight
Amid the technology age of satellite mapping and swelling popularity of trail cameras, wildlife experts are still tapping the fur trappers’ knowledge to seek out important data on elusive predators. In Alberta, for example, biologists are looking to gain a better understanding of wolverine distribution across the Canadian province, and reaching back through decades of trapper reports and observations to do it.
