The Great Burn Study Group

Through advocacy and on-the-ground stewardship, the Great Burn Study Group works to protect wildlands in the northern Bitterroot Mountains in western Montana and northern Idaho.

GBSG focuses on the preservation of a well-defined land base, leverages its modest resources thoughtfully, and invests in projects with a high probability of significant results. GBSG works hard to develop and support protective land management policies and the effective enforcement of those policies to preserve the wild and remote character, wildlife habitat, ecological integrity, and wilderness potential of the GBSG mission area.
