Grizzly Bear Trapping Announcement
 
BOZEMAN, MT - As part of ongoing monitoring efforts to document recovery of grizzly bears in the Greater Yellowstone Ecosystem under the Endangered Species Act, the U.S. Geological Survey, in conjunction with Yellowstone National Park, is working to inform the public that pre-baiting and scientific capture operations are once again about to begin within Yellowstone National Park. Agency biologists with the Interagency Grizzly Bear Study Team (IGBST) will begin the field captures May 1 and continue through Oct. 15. Capture operations can include a variety of activities, but all areas where work is being conducted will have major access points marked with warning signs. It is critical that all members of the public heed these signs.
 
Monitoring of the grizzly bear population is vital to ongoing research and management of grizzly bears in the Greater Yellowstone Ecosystem. To attract bears, biologists use natural food sources such as recently road-killed deer and elk. Potential capture sites are baited with these natural foods and if indications are that grizzly bears are in the area, culvert traps or foot snares are used to capture bears. Once captured, bears are handled in accordance with strict safety and animal care protocols developed by the IGBST and approved by the U.S. Geological Survey.

Whenever bear capture activities are being conducted for scientific purposes, the area around the site will be posted with brightly colored warning signs to inform the public of the activities occurring. These signs are posted along the major access points to the capture site. It is important that the public heed these signs and do not venture into an area that has been posted. For more information regarding grizzly bear capture efforts call the IGBST trapping hotline at 406-994-6675. Information about the grizzly bear research and monitoring is available from the IGBST website.
