Biologists begin grizzly bear research captures in Yellowstone

JACKSON HOLE, WYO — As part of ongoing efforts to monitor the population of grizzly bears in the Greater Yellowstone Ecosystem, Yellowstone National Park and the USGS would like to inform the public that biologists with the National Park Service and Interagency Grizzly Bear Study Team (IGBST) will be conducting scientific grizzly bear research operations in Yellowstone National Park from May 13 through July 31.

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

None of the trap sites in the park will be located near any established hiking trails or backcountry campsites. All trap 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 should 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 populations.

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