Interagency Grizzly Bear Study Team - Public Notifications and Resources

As part of ongoing efforts required under the Endangered Species Act to monitor the population of grizzly bears in the Yellowstone Ecosystem, The Interagency Grizzly Bear Study Team (IGBST) traps and monitors grizzly bears for research and monitoring purposes.

Trapping operations can include a variety of activities such as baiting and trapping, but all areas where work is being conducted will have major access points marked with warning signs. Specific bait or trap sites will have closure signs in the immediate vicinity. It is critical that all members of the public heed these signs.

As part of the IGBST Public Notification and Signing Protocol, the Grizzly Bear Trapping Hotline was developed to assist in notification of IGBST trapping operations, as well as serve as a public outreach tool for those with questions pertaining to IGBST trapping operations.

Below are the 2014 trapping announcements:

For more information about IGBST trapping operations, call the hotline at 406-994-6675, Monday – Friday.


NOTE: State and federal wildlife managers trap bears for both management and research purposes. For questions pertaining to non IGBST trapping activity, please call state and federal wildlife management officials directly.
