Defenders of Wildlife v. EPA
This case challenges the Environmental Protection Agency’s illegal registration of Rozol Prairie Dog Bait, containing chlorophacinone. EPA registered the rodenticide for use in 10 states without providing notice and an opportunity for comment as required by the Federal Insecticide Fungicide and Rodenticide Act. EPA also violated the federal Endangered Species Act by failing to consult with the U.S. Fish & Wildlife Service to ensure that expanded use of the poison would not impact threatened and endangered species.
Defenders of Wildlife and Audubon of Kansas are seeking stronger protections today for federally-protected animals that feed on poisoned prairie dogs. In addition to black-footed ferrets, many birds and raptors, including burrowing owls, bald and golden eagles, Swainson’s hawks, ferruginous hawks and turkey vultures, are at risk from use of these chemicals.
Rozol contains blood-thinning drugs that cause poisoned prairie dogs to slowly bleed to death through “various orifices, including eventually the skin membranes,” according to the U.S. Fish and Wildlife Service in a letter to the EPA opposing the registration. Predators and scavengers are secondarily exposed to the poison when they consume dead and dying prairie dogs that have eaten Rozol pellets.
The U.S. District Court for the District of Columbia ruled in favor of Defenders in July 2011, holding that EPA violated the ESA. Under the terms of the ruling, EPA withdrew registration for Rozol Prairie Dog Bait in four states pending completion of endangered species review with the FWS.
