The Oklahoma Natural Heritage Inventory (ONHI) provides information about Oklahoma's biodiversity to all interested parties. You may directly search for biodiversity information through the Oklahoma Biodiversity Information System (OBIS).
However, due to the sensitive nature of some of the data, precise locations and details is not publicly available.
Due to the sensitive nature of these data, ONHI typically only provides information to the section level (1 mi2) or coarser. This information is generally provided in tabular format. Please use our online form to make information requests.
Additionally, ONHI partners with NatureServe providing data for the Multi-Jurisdictional Dataset (MJD). Certain data requests, especially those covering large geographic areas (e.g. multiple states), as best handled by NatureServe.
