20240809 14324400 1.0 TRUE Watersheds Containing Rare and Imperiled Fish This dataset contains watershed locations of rare and imperiled fish collections compiled from various sources. Maintaining aquatic ecosystem health is critical for the conservation of a number of rare and imperiled freshwater mussel and fish species. This project employed Geographic Information System (GIS) models to rapidly evaluate and broadly describe streams based upon systemizing up-to-date statewide multi-scale spatial data capable of characterizing aquatic species habitats. Main data sets that were used to attribute the stream network included climate, ecoregions, ecological drainage units, and HUC-12 watersheds. We developed a statewide stream habitat classification GIS data layer that is necessary for the identification of existing and potential habitats of aquatic species. The classification scheme used a set of hierarchical stream habitat abiotic characteristics presumably correlated with the fine-scale stream characteristics important for aquatic species. The nested aquatic classification system crosses landscape-level ecosystem/hydrologic units for freshwater areas. The freshwater aquatic habitat classification provides adequate detail for conducting ecological GIS modeling and large- scale statewide and ecoregional assessments, finer watershed level assessments, as well as assessments at a scale of individual stream segments.
