Calling the proposed decision to rescind bison grazing permits on federal land “unlawful, factually incorrect, and procedurally deficient,” the Bozeman-based nonprofit conservation group American Prairie on Friday filed a protest with the Bureau of Land Management.

Another protest filing filed last week by the Coalition of Large Tribes — a group representing more than 50 Native American Tribes — warned of the unintended consequences the BLM decision could have on tribal buffalo herds.

In January, the Department of the Interior released the proposed decision to cancel grazing permits across seven allotments of land in Phillips County that American Prairie has utilized for its bison herd for years.
