Detailed Natural Heritage Inventory (NHI) data is granted for one of the following purposes: research, educational, environmental, land management or other similar authorized purposes. There are two ways to request detailed NHI data — a one-time request and an NHI data license.

What type of data request is right for you?

Choose from one of these options:

  • One-time data request is for a small number of records or data from a limited geographical area. No additional training is required—cost: $75/hr staff time.
  • NHI data license — This license is for ongoing access to NHI data for the initial planning of multiple projects, tasks, or a large geographical area. Additional training is required and can be completed online for $250 per trainee (training is valid for five years). Cost: varies based on the geographic area requested (see below).

How much does it cost?

It depends on the number of counties requested.

Request results, not access

If you need NHI data for an upcoming project, you can get results for your site through an Endangered Resources Review or Proposed Review (conducted by a certified reviewer). These reviews constitute a letter including NHI data for your site and required actions and recommendations needed to comply with Wisconsin state and federal endangered species laws.
