This USGS data release documents species distribution models for 271 fluvial fish species in their native ranges of the conterminous United States. Source data, supporting code and model results are documented in this data package. Boosted Regression Tree (BRT) models were used to develop presence/absence predictions for each of the National Hydrography Dataset Plus Version 2.1 stream segments within a species' native range. The predictions provided can be linked to the NHDPlusV2.1 geospatial dataset through the COMID to create a spatial depiction of the models. The primary results are stored in the file "BRT Predictions" and are provided in comma separated value (CSV) and Parquet file formats. Parquet file format...

We developed the North American Freshwater Migratory Fish Database (NAFMFD) that synthesizes current knowledge of migratory status, pattern, and behavior for native and non-native freshwater fish species throughout North America, including 1,241 species representing 79 families and 322 genera.

FISHTAIL: A decision support mapper for conserving stream fish habitats of the Northeast Climate Science Center (NECSC) region, extended to the Mississippi Basin for use in conservation planning applications such as the Gulf Hypoxia Initiative. Assessing current and future condition of fluvial habitats Human landscape disturbances occurring throughout the Northeast U.S. that include urbanization, agriculture, and dams have multiple effects on the region’s streams which support economically and socially valuable stream fishes. Changes in climate are expected to cause additional changes in stream habitats, including changing water temperatures, which will potentially alter future stream fish assemblages. To manage...

This shapefile contains fish habitat condition index (HCI) scores as well as specific disturbance indices for 6th level Hydrologic Unit Code (HUC12) watersheds of the Watershed Boundary Dataset. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among HUC12 units. In this data set, variable summaries are linked to HUC12 watersheds developed for the Watershed Boundary Dataset downloaded on March 18,...
