This taxon declined rapidly beginning near the turn of the century and was listed under the Endangered Species Act in 1973. We assembled all available information from a variety of sources to document recovery efforts from 1957 to 1999. For each greenback cutthroat trout population, we noted (1) the characteristics of recovery waters and dates of population discovery or introduction; (2) fish abundance estimates; (3) analyses of genetic purity; (4) salmonid fauna, removal efforts, and reinvasions; and (5) dates, sources, and numbers of fish used to establish populations. For each hatchery used to assist recovery, we noted (1) sources and numbers of fish delivered to them; (2) sources, sex ratios, and production of fish used to create particular year classes; and (3) dates, numbers, and sizes of hatchery fish shipped to establish wild populations or supplement other hatchery stocks. 517 $aRecovery history of greenback cutthroat trout 606 $aGreenback cutthroat trout$zSouth Platte River Watershed (Colo. and Neb.) 606 $aGreenback cutthroat trout$zArkansas River Watershed 606 $aWildlife recovery$zSouth Platte River Watershed (Colo. and Neb.) 606 $aWildlife recovery$zArkansas River Watershed 615 0$aGreenback cutthroat trout 615 0$aGreenback cutthroat trout 615 0$aWildlife recovery 615 0$aWildlife recovery 701 $aYoung$b Michael K$060392 712 02$aRocky Mountain Research Station (Fort Collins, Colo.) 801 0$bAGL 801 1$bAGL 801 2$bOCLCQ 801 2$bWAU 801 2$bOCLCQ 801 2$bGPO 906 $aBOOK 912 $a9910695794403321 996 $aRecovery history of greenback cutthroat trout$93453688 997 $aUNINA
