Origins of wolverine in California genetically verified
Date:4/29/2009

Century: Native or Long-Distance Immigrant?"

"We still can't be sure how this animal came to the Tahoe National Forest," said Bill Zielinski, one of the study's authors and a research ecologist at the Forest Service's Pacific Southwest Research Station. "But, this peer-reviewed study shows that other scientists agreed with our interpretation that it likely traveled here from the Rockies."

Zielinski said the photographed animal would have traveled more than 400 miles to reach the national forest if it naturally dispersed from the nearest Rocky Mountain population. He said if the wolverine was accidentally or deliberately transplanted, it would have more likely originated from an area where wolverines are more common and legally trapped, such as Alaska or the Yukon Territory.

Sierra Pacific Industries wildlife biologists also photographed the wolverine this winter using remote-controlled cameras on land it manages in California. Wildlife Genetics Laboratory scientists determined it to be the same wolverine photographed last year.
