Stream Monitoring

The purpose of the long-term monitoring of native fish streams is to better assess the conservation status of federally-listed and candidate fishes, particularly Gila Topminnow, Loach Minnow, Spikedace, and Roundtail/Gila Chub, as well as the co-occurring fish assemblage (including non-native species). Sampling efforts are focused on streams that are not being monitored under separate programs and where the species of interest (focal species) have been detected since 1980 and have not been determined to be extirpated. In addition, streams that have been repatriated with any of these species and have been proven established without augmentation for a minimum of five years are also monitored.

The primary goals of the monitoring are to detect the focal species in each stream, determine the distribution of the focal species within the occupied streams, and provide an estimation of relative abundance (assemblage structure) of the focal species compared to the co-occurring species. This information helps assess the conservation status of the populations and assists with the development of management strategies.
