Defenders of Wildlife Take Action

Stop the needless slaughter of hundreds of bison!

Yellowstone is home to one of the last genetically pure herds of bison left in North America. Up to 1,600 of this 4,600-strong herd could be killed under this appalling scheme, once again preventing the herd’s expansion and setting back bison restoration to other areas of their historic range.

Bison are icons of the American West. Slaughtered by the millions a century ago, they were driven to the brink of extinction. Today we have an opportunity to reverse this national wildlife tragedy. Tell Governor Steve Bullock to stop the slaughter and let bison roam outside of Yellowstone National Park!
