The mission of Wind Cave National Park is to preserve and protect the natural resources. Wind Cave National Park is 28,295 acres. Because of its relatively small size and because there are missing parts, park managers must take an active role in helping the ecosystems function as they might have in the past. This requires understanding how everything in the park relates and how the naturally operating system would have functioned. Park rangers work with researchers to replicate that natural system using prescribed fires, bison round-ups, and biological control of exotic plant species.

How we accomplish the mission of the park is determined by what we know about the park. The land, the animals, and the cave are all related and it is only when we understand the resources and their connections that we can best protect Wind Cave National Park.
