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).

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.
