Humpback chub (Gila cypha) are listed under the Endangered Species Act of 1973, as amended. In accordance with recovery goals finalized in 2002, a population estimate was completed for adult humpback chub in Westwater Canyon on the Colorado River. This population estimate was conducted from 1998 to 2000 with the objectives of obtaining population estimates for humpback chub and roundtail chub in Westwater Canyon. Sampling occurred during September and October throughout the three years of the study. Three passes were conducted annually with approximately one week between passes. The primary method of capture was via trammel netting with supplemental electrofishing on one pass per year. Population estimates were...

The Suitable Habitat boundary identifies areas inside the Greater Yellowstone Ecosystem where habitat is deemed suitable for supporting a viable and self-sustaining Yellowstone grizzly bear population into the foreseeable future. The boundary was established by the U.S. Fish and Wildlife Service (USFWS) and formalized in the 2007 Final Rule to remove the Yellowstone grizzly bear from federal protection as a Threatened species under the Endangered Species Act (72 FR 14866 – currently vacated).

Humpback chub (Gila cypha) are listed under the Endangered Species Act of 1973, as amended. In accordance with recovery goals finalized in 2002, population estimates were completed for adult humpback chub in Cataract Canyon on the Colorado River. The sampling was conducted from 2003 to 2005 with the objective of obtaining annual point estimates for humpback in the canyon. Sampling occurred between mid September and early November each of the three years of the study. Three sites were sampled for two nights on three occasions each year with approximately one week between sampling occasion. Approximately 28% (1.9 river miles) of the available habitat in Cataract Canyon was sampled on each occasion. The primary method...
