YELLOWSTONE NATIONAL PARK — Scientists are trapping grizzly bears in Yellowstone National Park as part of ongoing research on the protected animals.
Baiting and trapping of the bears starts on Tuesday and will continue through Oct. 31 in remote locations in the park, away from established trails and backcountry campsites.
Park officials say warning signs will be posted at all trapping sites and potential access points to them. People in the backcountry who happen upon the signs are asked to stay away from the area.
In June 2010, an Illinois man was killed six miles east of the park by a grizzly that had just reawakened after been trapped and tranquilized. The victim's widow is suing the federal government, claiming researchers prematurely took down warning signs.
The research is required by the Endangered Species Act.
