The dataset includes ecoregion specific species distribution models for 149 common fluvial fishes of the Conterminous U.S. Species models were developed for fluvial fishes considered common and native in each of the nine EPA Wadeable Streams Assessment program aquatic ecoregions (Herlihy et al. 2008) in which the species occurred. Common native species were identified as being geographically widespread and relatively abundant within ecoregions and utilize a wide variety of habitat types. Boosted regression tree models were used to develop presence/absence predictions for each of the National Hydrography Plus Dataset Version 1.0 (NHDPlusV1) stream reaches. The text files provided can be linked to the NHDPlusV1 data...
