Camera Spots Wolverine in Sierra Nevada - The Huffington Post
SACRAMENTO, Calif. — A research project aimed at weasels has turned up a bigger prize: a picture of a wolverine, an elusive animal scientists feared may have been driven out of the Sierra Nevada long ago by human activity.
The discovery could affect land-use decisions if the wolverine is declared an endangered species, a step the U.S. Fish and Wildlife Service is considering, although the animals typically live at high elevations where there is limited development.
A graduate student at Oregon State University, Katie Moriarty, got a picture of a wolverine recently on a motion-and-heat-detecting digital camera set up between Truckee and Sierraville, in the northern part of the mountain range.
Moriarty was trying to get pictures of martens, which are slender brown weasels, for a project she was doing with the U.S. Forest Service’s Pacific Southwest Research Station.
She said that when she saw the wolverine in the picture early last Sunday morning, it was a “complete shock. It was not something I would expect by any means.”
News of the picture surprised scientists, who thought wolverines, if they still inhabited the Sierra, would be found only in the southern part of the range, not in the Lake Tahoe area.
There had been sightings of wolverines by reputable people but no solid proof they were still in the Sierra, said Bill Zielinski, a research ecologist for the Forest Service who was working with Moriatry.
“The conventional wisdom was that they were pretty much gone from California,” said Zielinski. “There’s been a lot of other camera work and a variety of methods used to track rare carnivores. Those same methods, if wolverines had been around, would have detected them, we thought.”
