This gopher was found below about 5000 feet elevation in disturbed or
open areas from Cajon Wash at Devore westward all along the coastal base
of the San Gabriel Range. In the lower part of the chaparral belt the
gopher evidently was absent from the chaparral-covered slopes, but was
common along roads and on fire trails.
Burt (1932) and von Bloeker (1932) discuss the distribution of the three
subspecies of this species, _pallescens_, _neglecta_, and _mohavensis_,
which are in the San Gabriel Mountains area, and Burt indicates that
_pallescens_ grades toward _mohavensis_ in the southern part of Antelope
Valley.
