When searching by State, please note that a species will show up in the report only if it has a spatial current range. State associations for a species are based on a spatial current range delineated by FWS biologists in TESS (and not all species have spatial current range delineated at the present time).

The current range of species entities consisting of one or more populations does not include states or countries outside those population boundaries, even though the species may occur there in a population not covered by the Endangered Species Act.
