JACKSON, Wyo. (AP) — Researchers are studying the effects of winter recreation on wolverines in northwest Wyoming.

The research project headed by Round River Conservation Studies is being done in the Teton Range and is part of a larger study that has been going on for about five years.

Officials plan to continue the study through next winter.

Conservation science director Kim Heinemeyer tells the Jackson Hole News & Guide ( ) that researchers are attempting to determine how wolverines respond to winter recreation, including snowmobiling and backcountry skiing.

Heinemeyer says northwest Wyoming was chosen for the study because of the popularity of backcountry skiing in the area.

About a year ago the U.S. Fish and Wildlife Service announced it was recommending that North American wolverines be managed as “threatened” under the Endangered Species Act.___
