This dataset contains the components of and resultant Rarity and Climate Sensitivity (RCS) values for 90 species of frogs and toads native to the conterminous United States. The RCS metric uses point occurrences to describe area of occurrence, quantifies the variation of climate conditions within that area, and combines and scales the two for a multispecies assessment of intrinsic sensitivity to climate change. The RCS metric was calculated at two geographic extents, the conterminous US and the North American continent. We also used two spatial grains: 1 km buffered occurrence points and small watersheds (Hydrologic Unit Code (HUC) 12 watershed boundaries within and HydroBASIN level 12 watershed boundaries outside the conterminous US). Point occurrences from the Global Biodiversity Information Facility (GBIF) and HerpMapper were used to calculate area of occurrence at each spatial extent and grain size. Climate specificity was calculated by extracting three climate variables (annual precipitation, annual maximum temperature, and annual minimum temperature) from the area of occurrence and calculating the area-weighted standard deviation of each climate variable for each species. Rarity, as described by area of occurrence, and climate sensitivity is scaled and combined to form the RCS index. Because we evaluated the relationships among intrinsic sensitivity, taxonomy, and conservation status, species taxonomic family, genera, International Union for the Conservation of Nature Red List status, Endangered Species Act status, and Species of Greatest Conservation Need status is included in this dataset. Each row contains the calculated RCS index and its components for two spatial grain sizes for a unique species and spatial extent combination (90 species x 2 spatial extents = 180 rows).
