Red Squirrel - Taxonomy and Distribution

Taxonomy and Distribution

There have been over 40 described subspecies of the red squirrel, but the taxonomic status of some of these is uncertain. A study published in 1971 recognises 16 subspecies and has served as a basis for subsequent taxonomic work. At present, there are 23 recognized subspecies.
