Rumors of wolverines in Utah have swirled for decades, fed by occasional sightings in the state’s most remote reaches, like the Uinta-Wasatch-Cache National Forest. But the habitat of this reclusive animal, along with that of at least 100 other species — including dozens of native plants and amphibians — is threatened by the state’s quest to weaken federal protections for some of Utah’s most remote and undeveloped areas, according to a recent study from the Defenders of Wildlife.
