Issuing agencies

Abstract

We, the U.S. Fish and Wildlife Service (Service), announce our 90-day finding and 12-month determination on how to proceed in response to a petition to revise critical habitat for Sonora chub (Gila ditaenia) pursuant to the Endangered Species Act of 1973, as amended (Act). The petition requests that the Service revise the existing critical habitat designation in Arizona by adding California Gulch. Our 90-day finding is that the petition, in conjunction with information readily available in our files, presents substantial scientific information indicating that the requested revision may be warranted. Our 12-month determination is that we intend to proceed with processing the petition by assessing critical habitat during the next 5-year status review for Sonora chub scheduled for release as soon as fiscal year 2027, as resources allow.
