The Minnesota Conservation Explorer is a tool to enhance the delivery of Minnesota’s Natural Heritage Data and to automate the Natural Heritage Review process. This is a tool for the public to view and create maps of Natural Heritage Data for the purpose of conservation planning. Users can also submit a proposed project and request an automated assessment of potential impacts to Minnesota’s rare features. Go to the Minnesota Conservation Explorer

Obtaining NHIS Data

The Natural Heritage Information System (NHIS) is a collection of data layers that provides information on Minnesota's rare plants, animals, native plant communities, and other rare features.

• Obtaining NHIS Data / Fee Schedule
• License Agreement Application Form

Natural Heritage Screen

A Natural Heritage Screen is the process of checking for NHIS data in the vicinity of an activity/project to determine if further review is needed. The following optional checklist for recording results of an NH Screen may be useful to licensees and DNR staff conducting NH Screens.

• NH Screen Checklist

Natural Heritage Review

The purpose of a Natural Heritage Review is 1) to determine if there is any potential for a project to impact state-listed species or other rare features, and 2) to identify measures needed to ensure that a project is complying with state laws related to state-listed species and other rare features. A Natural Heritage Review must be conducted for all projects that meet the threshold for formal environmental review. Government units may also require a Natural Heritage Review as part of their license/permit/grant applications. Regardless of whether a Natural Heritage Review is required, compliance with state law is required. It is strongly recommended that all projects undergo a Natural Heritage Review as a project proposer’s due diligence for following state law and considering impacts to Minnesota’s Natural Heritage.
