Candidate Assessment

 

Candidate Species
Candidate species are plant and animal species for which the Service has sufficient information on their biological status and threats to propose them as endangered or threatened under the Endangered Species Act.  However, the development of a listing regulation for species on this list is precluded by other higher priority listing activities.

The Service uses listing priority numbers to select species from the candidate list to process on to the threatened and endangered list.  Listing priorities are based on magnitude of threat, immediacy of threat, and taxonomic distinctiveness.

Candidate Notice of Review
Each year, the Service publishes an updated Candidate Notice of Review (CNOR) to solicit new information on the status of the candidate species and threats to their survival.  The Service relies on contributions from private, university and government scientists, and other citizens, as well as, local, state, and federal land management and planning agencies. The Service reviews any new information on the species, reevaluates the listing priority number, and makes changes accordingly.
