Buffalo Field Campaign, Western Watersheds Project, and our attorneys at Friends of Animals recently notified the U.S. Fish & Wildlife Service of our intent to sue the agency for delaying a decision on whether Yellowstone bison should be listed as a threatened or endangered species.

The notice letter provides the wildlife agency 60 days to comply with the Endangered Species Act.

The U.S. Fish & Wildlife Service has indicated it will not complete its’ 12-month species status review and issue its’ finding on listing Yellowstone bison until September 2026.

Last June, Buffalo Field Campaign provided the wildlife agency a 492-page analysis of factors jeopardizing Yellowstone bison, and a way for honoring, protecting, and recovering robust wild herds in the bioregion in cooperation with Indigenous tribes. (Download BFC’s analysis, 22.5MB).

November 14, 2024, will mark the 10th year anniversary of our petition to protect and recover Yellowstone bison, and their range and habitat. It has been a long and protracted battle, and we thank each and every one of our supporters for being with us every step of the way.

As we take the next step towards protecting and recovering the unique and distinct wild herds roaming Yellowstone, please strengthen our campaign by making a donation to our May Flash Fund Drive. Thank you for your generous support!
