Flint Hills Tallgrass Prairie Preserve

This tallgrass prairie is set among low rolling hills of limestone strata that cover layers of sandstone, flint and chert. The headwaters of the South Fork of the Cottonwood River run through the property.

Why the Conservancy Selected this Site

To restore a functioning tallgrass prairie ecosystem, The Nature Conservancy purchased the preserve in 1972 and 1973 with funds provided by the late Katharine Ordway.

What the Conservancy is Doing

The Flint Hills typifies our commitment to large-scale projects that preserve the natural ecosystem and the human culture connected to that ecosystem, both of which are equally threatened.
