What Defenders is Doing to Help
Stopping the Bison Slaughter
Defenders of Wildlife is helping to find more places for bison to roam as wildlife.

Defenders has also been working with landowners in Gardiner Basin and Hebgen Basin near the north and west entrances to Yellowstone to come up with ways to live with bison that wander outside the park. To date, Defenders has chipped in more than $100,000 for fencing and other related project costs to help restore bison to tribal lands and to allow them to wander safely outside Yellowstone.
