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 almost 77,000 acres (120 square miles).
Our work to preserve the state's diverse habitats has resulted in a number of awards. Learn more ►
