BioDiversity is Our Goal

The Biological Survey is both a state agency and a research department of the University of Oklahoma. The Biological Survey includes the Oklahoma Natural Heritage Inventory, Oklahoma Natural Areas Registry, and the Robert Bebb Herbarium.  Our faculty and staff are committed to providing the best available information on biodiversity in the state of Oklahoma. We do this through our surveys, inventories, and research on the state’s biodiversity. We also collect, curate, and share existing biodiversity data. We are committed to training students and the public in biodiversity science. To achieve our goals we work closely with other allied organizations throughout the state and region.
