Wolverines in the US

Wolverines back in Colorado

July 20th, 2009 A single wolverine has returned to Colorado for the first time in 90 years. Wolverines used to be common south of Canadian border, but there are now only an estimated 250 to 500 wolverines in the lower 48 states. Wolverines were severely persecuted in the past by trappers who prized their almost waterproof fur, ranchers who killed them with poison bait and developers who divided their range with highways and other infrastructure.  New York Times According to the Colorado Wildlife Divsion “Occasional reports of wolverine sightings were investigated, but wolverines were never officially documented. In spring 2009, researchers with the Greater Yellowstone Wolverine Program tracked a wolverine from Grand Teton National Park south into north central Colorado utilizing satellite-collar technology. The wolverine was the first confirmed in the state in 90 years.”
