Wm B Richardson 1935 Peromyscus maniculatus Dec 23 4 mi NE Springville, 2800 ft. Tulare Co, Calif. Canyon 1 individual this morning. The trap was set in a relatively open plot at the edge of a rock within 4 ft of the river. Habitat area - Sierran Foothill Life zone - Upper Sonoran. Jan 14 Canyon G, 7 mi E Orovi, 200 ft. Tulare Co, Calif. From the 80 traps I took 42 animals of this species. Habitat area - Sierran foothill - San Joaquin Valley. Life zone - Upper Sonoran + Lower Sonoran. Habitat - It seems to be very broad, varying from the dense greasy hill slopes to the barns where baled hay is kept. They are generally to be found about rocks, brush or in grassy areas but were taken in some instances in relatively open areas where small open trails had been made. In several cases they were taken at the mouth of small burrows which I presumed belonged to them. The majority of the animals taken today were young. Jan 15 Took 22 of this species this morning. Habitat is principally grassy hill slopes about rock piles.
