Natural Heritage Inventory (NHI) training

DNR employees

Staff within many DNR programs are responsible for screening various types of projects and activities for potential impacts to endangered resources. It is required that this screening be conducted for any action the department conducts, funds or approves on private or public lands with the potential for impacting lands, wetlands or waterbodies.

For example:

  • Do you issue DNR permits or grants?
  • Do you conduct on-the-ground management work for DNR properties?
  • Do you update or build new DNR facilities?
  • Do you use the NHI Portal?
  • Are you responsible for conducting, funding or approving any department action?

Any DNR staff who use NHI data in their work are required to take this training and remain up-to-date every five years per Manual Code 1753.1 [PDF].

Authorized users (non-DNR employees)

Training is offered to individuals and organizations that have an NHI Data Sharing License. This training is intended to provide comprehensive information about the access, use, interpretation, application and security of the NHI data.

In order to receive and maintain access to detailed NHI data, authorized users are required to take the online NHI training and retake it every five years. Potential trainees should initiate the NHI data sharing license agreement process prior to registering for and taking the NHI training. By completing this training and passing a 25 question multiple choice, true/false exam, an individual becomes an authorized NHI data user.
