  "abstract": "We present a global environmental trait database for freshwater crayfish (Decapoda: Astacidea), integrating 115,191 georeferenced occurrence records from the World of Crayfish® platform with 398 environmental variables extracted through the Environment90m and GeoFRESH framework at 90 m resolution. Unlike conventional approaches that rely on terrestrial climate grids, our extraction addresses the dendritic structure of river networks such that each occurrence corresponds to a stream segment of the Hydrography90m stream network, thus providing variables at both local (segment-level) and upstream (catchment-aggregated) scales. Following a series of data quality checks, we retained 65,957 records across 273 taxa from all four extant families, namely Astacidae, Cambaridae, Cambaroididae, and Parastacidae. We summarized species-level environmental statistics using 20 descriptors of central tendency, dispersion, distributional shape, and niche breadth. The database is openly accessible through Mendeley Data1 and the World of Crayfish® platform without registration, providing an analysis-ready resource for species distribution modelling, invasion risk assessment, and conservation planning.",
