Service Description: This map illustrates the documented distribution of the western ridged mussel (Gonidea angulata) across Level 8 hydrobasin watersheds in western North America. Watersheds where historical occupancy could not be confirmed, but where circumstantial evidence suggests possible presence, are labeled as “uncertain watersheds.” A remnant population within the designated “study watershed” provides insights into the species’ natural history, phenotype, and associated ecological covariates.
