What We Do
The listing, delisting, and reclassification process may begin when the public requests it (via a petition), or it may be initiated by a status review such as candidate assessment, five-year review, or discretionary review. The ESA provides that any interested person or organization may petition us to add a species to the list, remove it from the list, or reclassify its status on the list. Through the candidate assessment process, we identify species for which the best scientific and commercial data available indicate that a proposal for listing is appropriate.
Our Projects and Initiatives
In order to provide the best possible conservation for imperiled species across the nation and beyond, we developed a set of workplans for addressing species status decisions on domestic and foreign (non-U.S.) species over the next several years. These workplans enable us to prioritize our workload based on species of greatest conservation need, while providing greater clarity and predictability about the timing of listing determinations.
