Tell U.S. Forest Service: DO NOT Poison 16,000 Prairie Dogs

May 19, 2014

The U.S. Forest Service is considering a plan to poison as many as 16,000 prairie dogs in Wyoming’s Thunder Basin National Grassland. Prairie dogs are a keystone species and vital to the survival of many other animals. Tell the Forest Service to reject this heartless plan.

In Wyoming, prairie dogs are slowly recovering from decades of hunting and disease, and Thunder Basin National Grassland contains some of their last protected habitat. But the U.S. Forest Service is considering a plan to poison any prairie dog colonies on the Grassland within a quarter-mile of private or state land. They could kill an estimated 16,000 prairie dogs, which are essential to the survival of many other species. Urge the Forest Service to reject this heartless and misguided plan.


I am outraged at the plan your agency is considering -- to kill an estimated 16,000 prairie dogs in Thunder Basin National Grassland. This would be inhumane to the animals and environmentally disastrous for the Thunder Basin ecosystem.

In 2009, in an exemplary decision, you set aside 85,000 acres of grasslands to provide a safe haven for prairie dogs from being shot, poisoned or gassed. Today, the Thunder Basin National Grassland is part of the remaining two percent of America's untouched prairie grasslands, and contains the best prairie dog habitat in the country. Prairie dogs are essential to the health of our grasslands but are victimized by misinformation and widely extirpated from their former range.

Furthermore, I understand the plan may call for anticoagulant poisons such as Rozol. Rozol, a barbaric poison, can take one to three weeks to kill prairie dogs. After being poisoned, they will bleed internally and externally, wandering more and more disoriented and vulnerable to predators. Animals that feed off of this keystone species -- including golden eagles, ferruginous hawks, swift foxes, turkey vultures, badgers, raccoons and coyotes -- will also fall victim to the poison and may die.

As a federal agency charged with protecting our nation's unspoiled flora and fauna, the Forest Service must turn down this plan to poison prairie dogs in the Thunder Basin National Grassland. Please find alternative methods for managing this species and the wildlife which depend on them.
