Abstract
Studies were initiated in June, 1994 by the USDA Forest Service, Rocky Mountain Forest and Range Experiment Station to update knowledge on the distribution of the Rio Grande cutthroat trout a Forest Service Sensitive Species, and its co-occurrence with two native cypriniforms, Rio Grande sucker and Rio Grande Chub. The Rio Grande sucker IS listed as endangered by the state of Colorado. The native cutthroat was found to co-occur with the native sucker in Tusas Creek on the Carson National Forest, and in the Rio de las Vacas, American Cr. and the Rito de las Palomas on the Santa Fe National Forest. By comparison, the native trout co-occurred with the chub in Canjilon Cr., El Rito Cr., Rio San Antonio, and Nutrias Cr. on the Carson National Forest. The three native species co-occurred in the Rio de las Vacas, Clear Creek, American Creek. and Rito de las Palomas on the Santa Fe National Forest. Seven new localities (Canada de Osha, Comales Cr., Agua Piedras, Rio de las Trampas, Rio San Leanardo, ltalianos Cr. and Yerba Creek) were added to the distributional records of the native cutthroat-all on the Carson National Forest. Two new localities were added to the know distribution of the native sucker (Polvedera Cr. and Canones Cr.).
