Requesting Oklahoma Federal or State Regulatory Species Data

For whom is this information intended?
We provide these data to the general public, environmental consultants, agency personnel: anyone who requires presence/absence information on Federal or State Listed Threatened, Endangered or Candidate species in Oklahoma.

Are there other options? I require more than presence/absence data, and for more than regulatory species.
Yes. Please contact Dr. Todd Fagin, ONHI Biotics Administrator, tfagin [at] ou [dot] edu, or call ONHI at 405.325.1985 for more information.

Can I get site specific information?
Yes. Given your site coordinates or your defined site boundary, we can search for occurrences within your project site. The smallest site area that we can “see” is about 3-5 acres ( 1-2 ha); anything smaller will be treated as a point site. We can also perform a data search within a pre-defined buffer zone surrounding your site, such as a corridor extending out either side of a pipeline, for example.

We provide location coordinates for species occurrences on request, with some restrictions for sensitive species. Generally, we just report species occurrences within your designated project boundary: scientific name, common name, state or federal status (if any) and last observed date (reported to us).

Can I get species presence lists, habitat, or general distribution information?
Yes. Call, or email us (see below) for more information. We can provide presence lists for irregular shaped boundaries, non-contiguous counties or townships, for example, or for other, non-geographic attributes.

Can I get a dump of the entire database?

What output data formats do you support?
Most often, our response to you will be in the form of brief correspondence, because we find either there are no occurrence records to report, or there are a only a few occurrences. Where appropriate, however, we provide tabular, CSV formatted output in a file (the default), or geospatial vector data in an ESRI Shapefile on request.

Geospatial data are provided only in decimal degrees of longitude and latitude, datum WGS84, spheroid WGS84.

How should I format my data request?
We prefer to receive data requests by email, but we are happy to correspond by U.S. postal service or by fax (see addresses and fax number below) if that is your preference. Your request should include:

  • A valid return email address, a postal address and a telephone number where we may reach you during business hours.

  • The site location (preferably shown with a vicinity or project boundary map file), or with Public Land Survey township, range & section, or latitude and longitude coordinates. If you include a portion of a USGS quadrangle on which the site occurs, be sure to also include the quadrangle name. If you send us a shapefile, please use the decimal degrees of latitude and longitude geographic coordinate system, WGS84 datum, for your coordinate reference. Please don’t ask us to convert your spatial data to our coordinate system.

  • A brief, general description of the nature of the project site, e.g., pipeline, waste water facility, pumping station and so forth.

How long will it take to get a reply?
We’ll respond to your request within 10 working days, and many times we’ll respond within a day of receiving it. We will be glad to work with you if you have an extra short deadline on a first-come, first-serve basis. Please note that this applies only to uninterpreted database searches: we search for records, we report record summaries to you. ONHI biologists handle interpreted data responses and that additional service will likely take longer than 10 days.

What will it cost me?

Is ONHI a regulatory agency?
No. The Oklahoma Natural Heritage Inventory is not a regulatory agency. It is a biological information source for interested persons or organizations. We cannot advise you about T&E species state or federal regulatory compliance or about applicability of state or federal endangered species law to your project. Regulatory agencies for endangered species in Oklahoma are The U.S. Fish and Wildlife Service in Tulsa, and the Oklahoma Department of Wildlife Conservation in Oklahoma City.

ONHI is a program of the Oklahoma Biological Survey, which is a research unit and state office located at the University of Oklahoma in Norman.

Data provided by the Oklahoma Natural Heritage Inventory are based solely on existing information in our databases. In the absence of field surveys, we cannot tell you whether a given site harbors rare species or significant natural communities.

The database is only as complete as the information that has been collected. For this reason we suggest you also contact the Oklahoma Department of Wildlife Conservation Natural Diversity Section (405.424.2728), or the U.S. Fish and Wildlife Service in Tulsa, Oklahoma (918.581.7458), as they may have information of which we are unaware.
