Requesting Detailed Data Access
Natural Heritage Inventory Data
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 — This 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 or tasks, or for 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 geographic area requested (see below).
How much does it cost?
It depends on the number of counties requested.
|Number of Counties||NHI Portal/GIS Shapefile|
|Up to four||$850|
|five or more||$1,500|

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.
