The ENM statistic workflow (ESW) allows the computation of the extent and intensity of change in species potential distribution through computation of the differences between two raster layers using the R statistical environment (R Core Team 2013). The difference file is computed from two input files (in this case present projection and 2050 projection). The difference between each corresponding raster cell value is computed and stored in the difference file, regardless of the input files’ geographical extent and origin.
