Natural Heritage Inventory training

Information for DNR staff and those seeking NHI license agreements

DNR employees

Staff within many DNR programs are responsible for screening various types of projects and activities for potential impacts on 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.
