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.

We are responisble for maintaining an inventory of the state's habitats and species. Our focus is on rare and endangered species, species of special concern, and significant ecological communities. Heritage biologists conduct field inventories of rare species and communities to gather current information about the state's biodiversity. We provide information for environmental planning, resource management, protection of significant natural areas, endangered species review, and biological research and education.
The Robert Bebb Herbarium (OKL) is maintained jointly by the Oklahoma Biological Survey and the School of Biological Sciences at the University of Oklahoma. The herbarium houses the largest collection of Oklahoma plants in the state. Specimens exceed 250,000 in number, with extensive collections of the families Poaceae, Asteraceae, Fabaceae, and Cyperaceae.
A voluntary conservation program for private landowners who have rare species, natural habitats, or unique geologic features on their property.
