What this data layer represents

This data layer shows point representations of occurrences of rare plants and high-quality terrestrial and aquatic ecosystems in Washington.

Location

a) Data encompasses the state of Washington.
b) Original element occurrence information was compiled at 1:24,000.

Description

The Washington Natural Heritage Program maintains a database of rare and imperiled species and plant communities for the state. The Element Occurrence (EO) records that form the core of the Natural Heritage database include information on the location, status, characteristics, numbers, condition, and distribution of elements of biological diversity using established Natural Heritage Methodology developed by NatureServe and The Nature Conservancy (TNC).

This layer DOES NOT include rare animals.  The points disappear when one zooms in to mask the precise location and provide a bit of protection for the rare taxa.
