This data release supports the referenced publication 'Climate futures for lizards and snakes in western North America may result in new species management issues' in this metadata record. Data included in this release includes raster data outputs and resulting summaries from the analyses, described in the processing steps of this metadata record. In summary this release includes information for 129 species and 1 genera of snakes and lizards in western North America. There are 7 rasters for each species and 6 summary rasters for the entire dataset, to total 916 rasters. For each species, rasters display a projected climate-niche at 6 time scenarios and 1 comparison between two scenarios. The summary rasters display calculated richness generated from the individual species rasters for a given time scenario. In addition to the raster data, each species includes an illustration of the comparison raster. The summary data files for this dataset include .csv files that describe the extent and changes of the projected climate-niche space.
