<br />Recovery Goals Provide Measures of Success <br /> <br /> <br />he U.S. Fish and Wildlife Service approved final, <br />basin-wide recovery goals for the endangered hump- <br />back chub, bony tail, Colorado pikeminnow, and <br />razorback sucker on August 1, 2002. The recovery goals were <br />developed with collaborative input from public, private, and <br />tribal stakeholders, and scientists from the Colorado River <br />Basin. The goals are based on the best available science and <br />provide reasonable assurances that recovery can be achieved <br />and the species protected into the future. <br /> <br />The Upper Colorado River Endangered Fish Recovery <br />Program and the San Juan River Basin Recovery <br />Implementation Program are using this information to <br />expand their efforts to bring the four fish species back from the <br />brink of extinction. The Recovery Programs are stocking <br />hatchery-produced fish, working to manage nonnative fishes, <br />and improving habitat to maintain or restore populations. <br /> <br />Consistent with the governing documents of the Upper <br />Colorado River and San Juan River Recovery Programs, the <br />recovery goals adhere to State and Federal laws related to the <br />Colorado River System ("Law of the River"), including State <br />water law, interstate river compacts, and Federal trust respon- <br />sibilities. <br /> <br />The recovery goals identify site-specific management actions <br />to minimize or remove threats and specify the numbers of fish <br />that comprise self-sustaining populations (see table below). <br />Downlisting of the fishes from "endangered" to "threatened" <br />and removing the species from Endangered Species Act pro- <br />tection (delisting) may be considered by the U.S. Fish and <br />Wildlife Service once the necessary management actions are <br />achieved and the fish populations reach the required demo- <br />graphic and genetic self-sustaining standards. <br /> <br />The recovery goals are comprehensive, biologically and legal- <br />ly sound, and provide specific criteria for recovery. Research- <br />based adaptive management, however, may lead to future <br />revisions of the recovery criteria. The recovery goals and the <br />status of the species will be formally reviewed at least every <br />five years. Monitoring of fish populations will help guide this <br />process, and population estimates will serve as a starting <br />point against which progress toward recovery is measured. <br /> <br /> <br />- <br /> <br />DEMOGRAPHIC CRITERIA FOR RECOVERY <br /> <br />DOWN LISTING <br /> <br />DELlSTING <br /> <br />Over a 5-year monitoring period: <br />· Maintain the six populations ("no net loss") <br />· One core population in upper basin> 2,100 adults <br />· One core population in lower basin> 2,100 adults <br /> <br />Humpback Chub <br />For 3 years beyond down listing: <br />· Maintain the six populations ("no net loss") <br />· Two core populations in upper basin> 2,100 adults <br />· One core population in lower basin> 2,100 adults <br /> <br />Over a 5-year monitoring period: <br />· Maintain reestablished populations in Green River and Upper <br />Colorado River Subbasins, each> 4,400 adults <br />· Maintain established genetic refuge of adults in lower basin <br />· Maintain two reestablished populations in lower basin, <br />each> 4,400 adults <br /> <br />Bony tail <br /> <br />For 3 years beyond downlisting: <br />· Maintain populations in Green River and Upper <br />Colorado River Subbasins, each> 4,400 adults <br />· Maintain genetic refuge of adults in lower basin <br />· Maintain two populations in lower basin, <br />each> 4,400 adults <br /> <br />Colorado Pikeminnow <br /> <br />Over a 5-year monitoring period: <br />· Maintain the upper basin meta population <br />· Maintain populations in Green River and Upper <br />Colorado River Subbasins ("no net loss") <br />· Green River Subbasin population> 2,600 adults <br />· Upper Colorado River Subbasin population> 700 adults <br />· Establish 1,000 age 5+ sub adults in San Juan River <br /> <br />For 7 years beyond down listing: <br />· Maintain the upper basin meta population <br />· Maintain populations in Green River and Upper <br />Colorado River Subbasins ("no net loss") <br />· Green River Subbasin population> 2,600 adults <br />· Upper Colorado River Subbasin population> 1,000 <br />adults OR Upper Colorado River Subbasin population <br />> 700 adults and San Juan River population> 800 adults <br /> <br />Razorback Sucker <br /> <br />Over a 5-year monitoring period: <br />· Maintain reestablished populations in Green River Subbasin <br />and EITHER in Upper Colorado River Subbasin or in San Juan <br />River Subbasin, each> 5,800 adults <br />· Maintain established genetic refuge of adults in Lake Mohave <br />· Maintain two reestablished populations in lower basin, <br />each> 5,800 adults <br /> <br />8 <br /> <br />For 3 years beyond down listing: <br />· Maintain populations in Green River Subbasin and EITHER <br />in Upper Colorado River Subbasin OR in San Juan River <br />Subbasin, each> 5,800 adults <br />· Maintain genetic refuge of adults in Lake Mohave <br />· Maintain two populations in lower basin, each> 5,800 <br />adults <br /> <br />2004-2005 Program Highlights <br />
