SurfaceStream_135x115

The key geologic feature common throughout the Ozark Plateau is the karst geological formations, which include underground caverns, sinkholes and streams, some of which resurface as natural seeps or springs. Many of the plants and animals found here are not only unique to the Ozark Plateau but to the specific cave or spring in which they are found.

History of Conservation

In 1903 President Theodore Roosevelt established the Pelican Island Bird Reservation, the first of 53 federal reserves he would create during his time in office and the roots of what is today known as the National Wildlife Refuge System. The 26th president was a dedicated naturalist throughout his life and is considered by many to have been the country’s “Conservationist President.” It was in the infancy of the Refuge System when President Roosevelt said, “There are no words that can tell the hidden spirit of the wilderness, that can reveal its mystery, its melancholy, and its charm.”
