Oklahoma's Illinois River

Protecting Oklahoma for Future Generations

The Nature Conservancy has worked to conserve Oklahoma’s magnificent landscapes and unique biodiversity since 1986. Using a strategic, science-based planning process, called Conservation by Design, we identify landscapes that, if conserved, promise to conserve biodiversity over the long term. The Oklahoma Chapter owns or protects 12 preserves totaling over 90,000 acres (140 square miles).

Our work to preserve the state's diverse habitats has resulted in a number of awards. Learn more ►

There are many organizations involved in the conservation effort in Oklahoma. Learn more ►
