Candidate and Proposed Species Under the Endangered Species Act (ESA)

Candidate species are any species that are undergoing a status review that we have announced in a Federal Register notice, whether or not they are the subject of a petition. For detailed definitions and explanations, please refer to the 2006 Candidate Species Definition (71 FR 61022, 10/17/2006).

Proposed species are those candidate species that were found to warrant listing as either threatened or endangered and were officially proposed as such in a Federal Register notice after the completion of a status review and consideration of other protective conservation measures. We always seek public comment on a proposal to list species under the ESA. We generally have one year after a species is proposed for listing under the ESA to make a final determination whether to list a species as threatened or endangered.
