Next Phase of Restoration.

Great herds of bison once roamed the prairies of our nation, including the Arbuckle Plains in Oklahoma, and were an integral part of our grassland ecosystems, along with fire. Because of their important role in maintaining native prairies, we plan to reintroduce bison to the recently expanded Oka' Yanahli Preserve.

We still have a ways to go to fund a bison herd and the research and infrastructure that it requires. However, during this time of celebrating bison as our newly-designated national mammal, we are delighted to share our plans to eventually return these iconic mammals to the Arbuckle Plains at Oka’ Yanahli Preserve as part of our long-term grasslands restoration process.

Support Our Efforts to
Return Bison to the Arbuckle Plains

Your gift will support the next steps towards returning bison to the Arbuckle Plains of Oklahoma. This is a long-term project and next steps will include feasibility research, fundraising, infrastructure development, land restoration and, when these are completed successfully… bison!



Oka' Yanahli Preserve

The Nature Conservancy and a suite of partners have teamed up to conserve an additional 3,100 acres of native prairie along the Blue River at Oka’ Yanahli Preserve in Johnston County.

This effort will not only conserve an important piece of Oklahoma’s disappearing native landscape, but it will also secure water quantity and enhance water quality for regional users of the Blue River. Over time, we will restore this land’s prairie species using nature’s own tools – rest, fire and grazing.
