Binned-probabilities suitability prediction for California Heuchera MRCA: Last Glacial Maximum, distance-buffer models

This is the suitability prediction for the MRCA of the California Heuchera clade (Heuchera caespitosa, Heuchera abramsii, Heuchera elegans, Heuchera parishii, Heuchera hirsutissima) for the Last Glacial Maximum (22k years ago), using distance-buffer models and normalized binned-probabilities maps.
