Natural Heritage Element Occurrences

The Natural Heritage Program collects information on occurrences of rare plants, animals, natural communities, and animal assemblages. Collectively, these are referred to as "elements of natural diversity" or simply as "elements." Locations of these elements are referred to as "element occurrences."

Use our Data Explorer or Database Search for information on element occurrences.

Many element occurrences are on private land and are not accessible without landowner permission.
