To best manage the National Bison Range for resident plant and wildlife resources as well as maintaining it as a trust resource for the public, we need to know what we have, how things are changing, and what we can do to keep the Refuge as healthy and natural as possible. We are involved in a variety of surveys, censuses, and research to obtain baseline data and to monitor management practices.

National Bison Range Natural Resources

Refuge employees, researchers, students and volunteers conduct surveys of refuge plants and wildlife in an effort to determine which species are present and to monitor the status of known plant and animal populations.

Research is also conducted to determine animal and plant baseline data, to monitor trends in populations and in changes in the natural communities, and to measure management effectiveness. In addition, a number of researchers have projects on the refuge under Special Use Permits. Current studies include bighorn sheep, pronghorn antelope, grasshoppers, rattlesnakes, water quality, biological weed control and bison DNA testing.

Climate Change

A growing body of scientific evidence has linked accelerating climate change with observed changes in fish and wildlife, their populations, their migratory patterns, and their habitats. But, if we act now, the damaging effects of climate change can be reduced. The U.S. Fish and Wildlife Service implements a partnership-driven and science-based strategic plan for addressing the impacts of climate change.
