U.S. Threatened and Endangered Species
The federal government has listed nearly 1,400 species as threatened or endangered. A number of additional species are under review for potential listing, changes to their listing status or revision of critical habitat designation.1 Unfortunately, there is no single, definitive public list of all species in the U.S. under review.
Texans can learn more about the impact of the Endangered Species Act (ESA), however, by tracking these issues through several different sources.
Two federal agencies are responsible for implementing the ESA — the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS).
FWS is responsible for terrestrial and freshwater species.
- See FWS species proposed for listing by state.
- See FWS candidates for listing by state. Candidates are species FWS believes warrant listing, but is not acting upon at present due to other, more pressing priorities. They may be proposed for listing at a later date.

NMFS is responsible for most marine species.
