AGENCY:

Fish and Wildlife Service, Interior.

ACTION:

Notice of initiation of reviews; request for information.

SUMMARY:

We, the U.S. Fish and Wildlife Service, are initiating 5-year status reviews under the Endangered Species Act for 56 species. A 5-year status 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 reviews.

DATES:

To ensure consideration of your information in our reviews, we must receive your comments or information on or before May 8, 2026. However, we will continue to accept new information about any species at any time.

ADDRESSES:

For instructions on how to submit information for a species, see table 1 in the SUPPLEMENTARY INFORMATION section.

FOR FURTHER INFORMATION CONTACT:

To request information on specific species, contact the appropriate person in the table in the SUPPLEMENTARY INFORMATION section or, for general information, contact Bjorn Erickson, via phone at (916) 414-6741, via email at , or via U.S. mail at U.S. Fish and Wildlife Service, 2800 Cottage Way, Suite W-2606, Sacramento, CA 95825. Individuals in the United States who are deaf, deafblind, hard of hearing, or have a speech disability may dial 711 (TTY, TDD, or TeleBraille) to access telecommunications relay services. Individuals outside the United States should use the relay services offered within their country to make international calls to the point-of-contact in the United States.

SUPPLEMENTARY INFORMATION:

We, the U.S. Fish and Wildlife Service, are initiating 5-year status reviews under the Endangered Species Act of 1973, as amended (ESA; 16 U.S.C. 1531 et seq.), for 22 animal species and 34 plant species. A 5-year status review is based on the best scientific and commercial data available at the time of the review; therefore, we are requesting submission of any such information that has become available since the last review for the species, particularly information on the status, threats, and recovery of the species.

Why do we conduct a 5-year review?

Under the ESA, we maintain Lists of Endangered and Threatened Wildlife and Plants (which we collectively refer to as the List) in title 50 of the Code of Federal Regulations (CFR) at 50 CFR 17.11 (for wildlife) and 50 CFR 17.12 (for plants). Section 4(c)(2)(A) of the ESA requires us to review each listed species' status at least once every 5 years. Our regulation at 50 CFR 424.21 requires that we publish a notice in the Federal Register announcing that a species is under active review. For additional information about 5-year reviews, refer to our fact sheet at https://www.fws.gov/​project/​five-year-status-reviews.

What information do we consider in our review?

A 5-year status 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 current listing determination or most recent status review of each species, 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 that benefit the species;

D. Threat status and trends in relation to the five listing factors (as defined in section 4(a)(1) of the ESA); 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 status review and will also be useful in evaluating the ongoing recovery programs for the species.

Which species are under review?

This notice announces 5-year status reviews for the species listed in table 1.
