ESA Protection Sought For Imperiled Yellowstone Bison

Western Watersheds Project and Buffalo Field Campaign petitioned the U.S. Fish and Wildlife Service (USFWS) today to list the Yellowstone bison under the Endangered Species Act. Yellowstone bison are found primarily in Yellowstone National Park and migrate into the jurisdictions of Montana, Idaho, and Wyoming where the wildlife species is forcibly removed or destroyed completely. Yellowstone bison are the only extant wildlife population of plains bison that retains its genetic integrity and still freely roams in the United States. Nearly all plains bison in the United States are private livestock and/or descendants of bison that were commercially interbred with cattle. These hybridized cattle-bison no longer retain their identity as plains bison, or status as a wildlife species in privately owned herds. All privately owned bison are managed as livestock. Nearly all publicly held bison exist in small, isolated populations on restricted and fenced ranges with no predators and subject entirely to human selection. The best available science presented in the petition shows that the Yellowstone bison are unique, significant, and genetically and behaviorally distinct. For this reason, the Yellowstone bison population is critical to the overall survival and recovery of the species. “Prompt listing under the Endangered Species Act is required if this last remnant population of plains bison is to survive and recover,” stated Travis Bruner of Western Watersheds Project. “The extirpation of the unique Yellowstone bison would represent the complete loss of wild bison from the last stronghold of their historic and ecological range, loss of unique ecological adaptations to the local environment, and the loss of valuable and unique genetic qualities.” stated Michael Connor of Western Watersheds Project. The petition catalogues the many threats that Yellowstone bison face. Specific threats include: extirpation from their range to facilitate livestock grazing, livestock diseases and disease management practices by the government, overutilization, trapping for slaughter, hunting, ecological and genomic extinction due to inadequate management, and climate change...more
