Trapping of bears in Yellowstone National Park will be conducted in the coming week as part of ongoing research into grizzly and black bears in the Greater Yellowstone Ecosystem/NPS

As part of ongoing efforts to monitor the population of grizzly bears and black bears in the Greater Yellowstone Ecosystem, biologists with the National Park Service and Interagency Grizzly Bear Study Team will be conducting scientific grizzly bear and black bear research operations in Yellowstone National Park from August 21 through October 31. 

Team members will bait and capture bears at several remote sites within Yellowstone. Once captured, the bears are anesthetized to allow wildlife biologists to radio-collar and collect scientific samples for study. All captures and handling are done in accordance with strict protocols developed by the IGBST. 

None of the capture sites in the park will be located near any established hiking trails or backcountry campsites, and all sites will have posted warnings for the closure perimeter. Potential access points will also be posted with warning signs for the closure area. Backcountry users who come upon any of these posted areas need to heed the warnings and stay out of the area. 

The Interagency Grizzly Bear Study Team was established in 1973 to collaboratively monitor and manage ecosystem bears on an interagency basis. The gathering of critical data on bears is part of a long-term research and monitoring effort to help wildlife managers devise and implement programs to support the ongoing conservation of Yellowstone’s grizzly bear and black bear populations. 

The IGBST is composed of representatives of the U.S. Geological Survey, the National Park Service, the U.S. Fish and Wildlife Service, the U.S. Forest Service, the Eastern Shoshone and Northern Arapaho Tribal Fish and Game Department, and the states of Idaho, Montana and Wyoming.
