Hoffmeister 1940 Peromyscus truei July 7 2 mi. S Guerneville, 200 ft., Sonoma Co., Calif. Caught an adult(?) male in the gully bottom leading down to the Russian River. The gully did not, at any place, have a very dense undercover of braches and vines and little or no poison oak. The taller trees shading (although not completely) the gully were redwoods, Umbellularia, Alnus, one or two Pseudotsuga taxifolia. There was some Lithocarpus and poison oak along the edge of the gully. The ground was not thickly covered with leaves or leaf-mold. Immediate vicinity of trap with P.truei was a fern 2 ft. high, small pile (10) of sticks, and a small vine. Animal was infested with fleas 10+, mites (numerous), and 1 tick (only the latter was saved). The testes were "down" and very large, measuring 24 mm. The animal was not overly fat, but apparently these animals are naturally large, the specimen weighing 36 grams. This habitat seems to be no different than the other I have (unsuccessfully) tried to catch truei in around here.
