- 2006 Forest Plan Amendment for Grizzly Bear Habitat Conservation for the Greater Yellowstone Area National Forests
In April 2006, the Forest Service amended forest plans on Greater Yellowstone Area national forests (Beaverhead-Deerlodge, Bridger-Teton, Caribou-Targhee, Custer Gallatin, and Shoshone National Forests) to incorporate the habitat standards and other relevant provisions in the Final Conservation Strategy for the Grizzly Bear in the Greater Yellowstone Area. The Record of Decision (ROD) presents the three principal reasons officials selected Alternative 2-Modified. In addition, the decision document describes the public involvement process and issues, and other alternatives considered. The amendment to the six forest plans is contained in the appendix of the decision document.

The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem. The full list of their publications can be found on the IGBST website.
