Providing BioDiversity Information

Oklahoma Natural Heritage Program is 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 this information for environmental planning, resource management, protection of significant natural areas, endangered species review, and biological research and education.
