Imperiled or Significant Species by Worldwide Status

This map was originally presented in the Wisconsin DNR Handbook entitled "Ecological Landscapes of Wisconsin."

The data shown on this map are part of the Natural Heritage Inventory (NHI). Each "element" of the NHI consists of one rare or naturally significant species or community. An "occurrence" of an element is a locational record representing a single, extant habitat, which sustains or otherwise contributes to the survival of a population or self-sustaining example of a particular element. An element rank is based on the number of occurences of that element worldwide. A statewide ranking system also exists.

This NHI is not a comprehensive survey, and negative data are not tracked. Therefore, abscence of an occurrence at a point is not evidence that that element does not occur at that location.
