The U.S. Geological Survey, in partnership with Yellowstone National Park, has announced plans to initiate grizzly bear captures for research purposes. The operation, which is part of ongoing efforts to monitor the recovery of grizzly bears in the Greater Yellowstone Ecosystem under the Endangered Species Act, will see agency biologists from the Interagency Grizzly Bear Study Team (IGBST) conducting field captures from September 1 to October 15, 2025.
This scientific capture operation is a recurrent event within Yellowstone National Park, aimed at gathering vital data about the grizzly bear population. The process involves pre-baiting and scientific capture operations, which are essential for the monitoring and documentation of the bear species’ recovery in the ecosystem.
The public is being informed about these operations to ensure awareness and safety. The captures are conducted by highly trained professionals from the IGBST, who are committed to the welfare of the grizzly bears and the safety of park visitors. No further details about the specific capture locations or methods were provided in the release.
