conducting scientific grizzly bear research operations in Yellowstone
National Park from September 11 through October 31, as part of the ongoing
monitoring of the activities and population of grizzly bears within the
Greater Yellowstone Ecosystem.
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 are done in accordance with IGBST’s
long established protocols.
None of the trap sites in the park will be located near any established
hiking trails or backcountry campsites, and 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 need to heed the warnings and stay out of
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 the protected bears is part of a
long-term research effort required under the Endangered Species Act to help
wildlife managers devise and implement programs to support the ongoing
recovery of Yellowstone’s grizzly bear population.
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.
