Purple lines = boundaries delimiting major watersheds (level 3 hydrologic unit compartments – HUCs); red dots = museum and literature occurrence records of native populations based on Iverson (1992), plus more recent and authors’ data; yellow dot = introduced population; large green dots with black centers = Pleistocene and Holocene fossils referred to ; green shading = projected current distribution based on GIS-defined level 8 HUCs constructed around verified localities and then adding HUCs that connect known point localities in the same watershed or physiographic region, and similar habitats and elevations as verified HUCs (Buhlmann et al.
