Petition Process

If a petition to list a species presents substantial information that the petitioned action may be warranted, a positive 90-day finding is published in the Federal Register and the species becomes a Candidate for listing under the ESA.

If a petition to delist a species presents substantial information that the petitioned action may be warranted, a positive 90-day finding is published in the Federal Register and the species goes under review for delisting under the ESA.

If a petition does not present substantial information, a negative 90-day finding denying the petition is published in a Federal Register notice.

More information on how species are listed under the ESA is also available.
