Delisted Species Under the Endangered Species Act (ESA)

Species under review for delisting are those petitioned species that are currently listed as threatened or endangered under the ESA but are actively being considered for removal from the list. NMFS may be petitioned to delist a species or may self-initiate an ESA status review that it has announced in the Federal Register (see "How species are listed").

Proposed for delisting are those species that were found to warrant delisting 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. Public comment is always sought on a proposal to delist species under the ESA. NMFS generally has one year after a species is proposed for delisting under the ESA to make a final determination.

Delisted species are those species that were formerly listed as threatened or endangered under the ESA but have since been removed because of their status.
