Grizzly Kills Man Near Wyoming's Yellowstone Park

CHEYENNE, Wyo. -- A grizzly bear killed a Wyoming man outside Yellowstone National Park, apparently just hours after researchers trapped and tranquilized the animal.

The researcher found Evert's body where they had left the bear to wake up, about two miles from Evert's cabin.

"My heart goes out for the victim and the family involved in this. Nobody would want anything like this to happen," Chuck Schwartz, head of the Interagency Grizzly Bear Study Team based in Bozeman, Mont., said Friday.

Potential Impacts of Climate to Timing of Grizzly Bear Denning

Past research by the Interagency Grizzly Bear Study Team (IGBST) observed a trend towards later den entry during 1975-99 among adult male bears, and a corresponding trend of increasing minimum fall temperatures during the same period, which may be attributed to climate change. Climate-influenced changes in timing of den entry has implications for managers tasked with minimizing conflicts between bears and humans, particularly during fall ungulate hunting seasons. Results of this analysis are pending and if earlier observed trends are confirmed IGBST will discuss the potential impacts on both bears and people of a longer active season for grizzly bears in the GYE.
