Reclassification of the Humpback Chub from Endangered to Threatened with a Section 4(d) Rule (Final)
Oct. 18, 2021
USFWS are reclassifying the humpback chub (Gila cypha) from endangered to threatened under the ESA, due to substantial improvements in the species' overall status since its original listing as endangered in 1974. This action is based on a thorough review of the best available scientific and commercial information available, which indicates that the humpback chub no longer meets the definition of an endangered species under the Act. The humpback chub will remain protected as a threatened species under the Act. They are also finalizing a rule under section 4(d) of the Act that provides for the conservation of the humpback chub. This rule is effective 17 November 2021. POC is Tom Chart, Director, tele: 303-236-9885.
