Five-Year Reviews
The U.S. Fish and Wildlife Service is required to review the status of each federally listed species every five years. These five-year reviews evaluate whether a federally listed species should be delisted, reclassified from endangered to threatened, reclassified from threatened to endangered, or if the species' classification should not change.
A Brief Explanation of Five-year ReviewsThe best, available scientific data is considered for a five-year review, particularly information that has become available since the current listing determination or most recent status review of the species. Such information includes:
The review assesses: (1) whether new information suggests that the species is increasing, declining, or stable; (2) whether existing threats are increasing, unchanged, reduced, or eliminated; (3) if there are any new threats; and, (4) if any new information or analysis calls into question any of the conclusions in the original listing determination as to the species' classification.
The five-year review provides a recommendation, with supporting information, on whether a species classification should be changed; it does not change the species' classification. A species classification cannot be changed until a formal rulemaking process is completed, including a public review and comment period.
