Fishes of the Upper Colorado River Basin have one of the highest levels of endemism in the United States. The range and abundance of these fish has declined over the last century and continues to decline as a result of legacy impacts from past management practices, current water management, interactions with non-natives, and other impacts. Seven of these fish are considered imperiled by the American Fisheries Society and four are listed as endangered by the U.S. Fish and Wildlife Service. We applied a complementarity-based approach to develop priority ranks (0 – 1; low to high) for catchments in the Upper Colorado River Basin. We used methods and a framework that we had previously developed for the Lower Colorado...

Conservation rank data for each drainage catchments in the Upper Colorado River Basin. Some smaller catchments were not ranked. Catchments are the drainage area (local watersheds) for each individual stream segment within the 1:100,000 scale National Hydrography Plus Version 1 (NHDPlusV1) dataset. The NHDplus catchments have been ranked (valued) based on the representation of native fish species given the threats to their persistence (i.e., non-native fish species, land use, and habitat fragmentation). The ranking process placed importance on areas with several native species as well as areas important to individual species with restricted distributions and so is not simply a species “hot spot” assessment. Catchments...
