Yesterday, the U.S. Fish and Wildlife Service announced that wolverines will now be listed as a threatened species under the Endangered Species Act. The ruling was hailed by conservation groups which have been advocating to protect wolverines in the contiguous U.S. for more than 20 years, including suing the agency twice. There are roughly 300 wolverines spread across Montana, Idaho, Wyoming and Washington. The new federal listing does not apply to wolverines in Alaska. Wolverines are already listed as a threatened species in Oregon and hunting or trapping of the animals is prohibited. Earlier this spring, several wolverine sightings were reported along the Columbia River and in the Central Cascades, most likely of the same animal. Bethany Cotton is the conservation director for Cascadia Wildlands, based in Eugene. She joins us to talk about the impact of this ruling, and ongoing threats to the survival of wolverines in the West.
