# Endangered and Threatened Wildlife and Plants; Initiation of 5-Year Status Reviews of 20 Listed Species in the Mountain-Prairie Region
**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 of 1973, as amended, for 20 species in the Mountain-Prairie Region. A 5-year status review is based on the best scientific and commercial data available at the time of the review. We are requesting submission of any such information that has become available since the previous 5-year status review for each species.
**DATES:**
To ensure consideration, please submit your written information by November 14, 2025. However, we will continue to accept new information about any listed species at any time.
**ADDRESSES:**
For instructions on how to submit information for each species, see table 1 in the *SUPPLEMENTARY INFORMATION* section.
**FOR FURTHER INFORMATION CONTACT:**
To request information, contact the appropriate person in table 1 in the *SUPPLEMENTARY INFORMATION* section. For general information, contact Karen Newlon, Regional Recovery Project Manager, by phone at 406-430-9010 or by email at *[email protected].* 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 are initiating 5-year status reviews under the Endangered Species Act of 1973, as amended (Act; 16 U.S.C. 1531 *et seq.* ) for 14 plants and 6 animals in the Mountain-Prairie Region. 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 he most recent status review for each species.
Why do we conduct 5-year status reviews?
Under the Act (16 U.S.C. 1531 *et seq.* ), we maintain Lists of Endangered and Threatened Wildlife and Plants (which we collectively refer to as the List) in the Code of Federal Regulations (CFR) at 50 CFR 17.11 (for animals) 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. Our regulations at 50 CFR 424.21 require that we publish a notice in the *Federal Register* announcing those species under active review. For additional information about 5-year status reviews, go to *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 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 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 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 status review and will also be useful in evaluating the ongoing recovery programs for the species.
