Vulnerability of Critical Fish Habitat to Oil and Gas Development in the Green River Basin

For the Green River Basin Landscape Conservation Design (GRB LCD) assessment, we mapped the vulnerability of the critical habitat for threatened and endangered fish species to oil and gas development for each 12-digit hydrologic unit. The following threatened and endangered fish species were included in this vulnerability assessment: Colorado pikeminnow (Ptychocheilus lucius), Bonytail Chub (Gila elegans), Humpback chub (Gila cypha), and razorback sucker (Xyrauchen texanus). Using a vulnerability framework, we defined Sensitivity (S) as the average combined area of critical fish habitat within HUC12 polygons. Exposure (E) to oil and gas development was quantified the log transformed upstream flow accumulation of...

An Evaluation of the Role of Tributary Streams for Recovery of Endangered Fishes in the Upper Colorado River Basin, with Recommendations for Future Recovery Actions

We evaluated the role of major tributary streams for endangered fish recovery using a matrix approach based on quantitative information. However, the need for ranking tributaries for direct and indirect contributions (i.e., assignment of high, medium or low importance) required a more subjective approach. Some streams differed in actual and potential importance because barriers deny fish access to suitable habitat. We have not assigned relative importance to the different types of contributions; to a large extent that may involve policy issues better addressed by the Recovery Program.

Juvenile native fish and sedative data from a laboratory and field experiment

These data were compiled for a study evaluating if rare or endangered fishes (e.g., Humpback Chub and Bonytail) can be transported in a shipping bag with 1-L of water and minimal sedative into remote locations. There were two components (laboratory trials and a field trial) of the study conducted in 2014 and 2017. Laboratory trials were conducted at the Rocky Mountain Research Station in Flagstaff, Arizona to evaluate three sedatives: AquaCalm, Tricaine-S, or Aqui-S 20E. Pilot trials were conducted with five fish (Bonytail) placed in a bag, where induction/recovery times, level of sedation, and fate after release were monitored for fish exposed to a sedative. Fish density increased to 20 fish (Bonytail and Humpback...

Population Estimates for Humpback Chub (Gila cypha) in Cataract Canyon, Colorado River, Utah, 2003–2005

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...
