Support the Development of a National Park Service Midwest Region bison stewardship strategy

Bison have played a key role in shaping the grasslands of the Great Plains for millennia. National Parks are a major last bastion for wild herds of the national mammal and symbol of the Department of the Interior. However, even as the National Park Service aims to maintain as natural as possible ecosystem conditions within its parks’ boundaries, managers regularly make decisions affecting their...

Grazing resources for integrated conservation of bison and native prairie at Badlands National Park, South Dakota

Badlands National Park (BADL) contains one of the largest protected expanses of mixed-grass prairie in the United States, much of which supports a herd of nearly wild bison. The park nevertheless is too small to accommodate bison’s natural nomadic behavior, which in the past resulted in their ephemeral but intense influence on Great Plains grasslands. This research is assessing the spatial...

Effects of population density on prevalence of chronic wasting disease, physical condition, and vital rates of elk at Wind Cave National Park, South Dakota

CWD is a degenerative neurological disease caused by infectious proteins called prions. Although documented cases are invariably fatal, infected elk commonly survive for several months or longer, passing prions directly to other individuals and into the environment, where they bind to surfaces or soils and can persist for years. CWD reached Wind Cave National Park about 1997 and rapidly became the...

Integrated conservation of bison and native prairie at Badlands National Park, South Dakota

Badlands National Park contains the largest contiguous bison range in the core of the species’ historic range on the northern Great Plains. The park nevertheless is too small to accommodate natural movements of free-ranging bison. As a result, continual grazing by resident bison has supplanted intense-but-ephemeral grazing by nomadic bison. The herd also is currently too small to prevent gradual...
