Researchers to trap Yellowstone bears as part of research

Wildlife biologists will be baiting and trapping grizzly bears in Yellowstone National Park from May 13 through July 31 as part of ongoing research.

The research by the National Park Service and Interagency Grizzly Bear Study Team is to monitor the population of grizzly bears in the Greater Yellowstone Ecosystem in Wyoming, Montana and Idaho.

Officials say none of the trap sites in the park will be located near any established hiking trails or backcountry campsites and closure warnings will be posted around all trap sites for any recreationists in the area.

Backcountry users who come upon any of the posted areas need to stay out of the area.

In 2010, a man was killed near Yellowstone by a grizzly bear that had recently been captured and released by researchers.
