Fish and Wildlife Service, Interior.


Notice of initiation of reviews; request for information.


We, the U.S. Fish and Wildlife Service, are initiating 5-year status reviews of 76 species in California and Nevada under the Endangered Species Act. A 5-year review is based on the best scientific and commercial data available at the time of the review; therefore, we are requesting submission of any new information on these species that has become available since the last review.


To ensure consideration in our reviews, we are requesting submission of new information no later than July 19, 2021. However, we will continue to accept new information about any species at any time.


For how and where to send information and comments, see Request for New Information. For whom to contact for species-specific information, see Request for New Information. Individuals who are hearing impaired or speech impaired may call the Federal Relay Service at 800-877-8337 for TTY assistance.

Why do we conduct 5-year reviews?

Under the Endangered Species Act of 1973, as amended (Act; 16 U.S.C. 1531 et seq.), we maintain lists of endangered and threatened wildlife and plant species (referred to as the List) in the Code of Federal Regulations (CFR) at 50 CFR 17.11 (for wildlife) and 17.12 (for plants). Section 4(c)(2)(A) of the Act requires us to review each listed species' status at least once every 5 years. For additional information about 5-year reviews, refer to our factsheet at​endangered/​what-we-do/​recovery-overview.html.

What information do we consider in our review?

A 5-year review considers all new information available at the time of the review. In conducting these reviews, we consider the best scientific and commercial data that have become available since the listing determination or most recent status review, such as:

(A) Species biology, including but not limited to population trends, distribution, abundance, demographics, and genetics;

(B) Habitat conditions, including but not limited to amount, distribution, and suitability;

(C) Conservation measures that have been implemented to benefit the species;

(D) Threat status and trends in relation to the five listing factors (as defined in section 4(a)(1) of the Act); and

(E) Other new information, data, or corrections, including but not limited to taxonomic or nomenclatural changes, identification of erroneous information contained in the List, and improved analytical methods.

Any new information will be considered during the 5-year review and will also be useful in evaluating the ongoing recovery programs for the species.
