Dipodomys heermanni berkeleyensis Grinnell, 1919
Berkeley's kangaroo rat
Taxonomy & Nomenclature
Invalid (synonym) (Benedict et al., 2019).
Last record: >65 years ago (Goldingay et al. 1997:52); 1980's (Gitelman, 2000:6)
The decline of this (now invalid) subspecies, and presumed extinction, was apparently due to poisoning campaigns which targeted ground squirrels in the 1940's and 1950's but which evidently affected other species including Dipodomys heermanni berkeleyensis (Gitelman, 2000).
