Bufo boreas (53)
Oct. 10 1.3 mi. N, 0.2 mi. W of Civic Center, Richmond,
Contra Costa Co., Calif. A quick check of this
huge area adjacent to S.B. tracks revealed no
frogs. The pond(2) is dried up, but moisture
present under some flat-lying boards and auto
tires. General Toxica tosa and one Hydra
found in such situation. Soil surface temperature
under board 4:40 P.M. (D.S.) with bulbs slotted
was 19.1° C. Air temperature foot above ground
(bulbs slotted) 20.1° C. No standing water at
all. The tule growth includes plants 77 feet
height. Much of the tule and grass vegetation
is beaten down presumably by the small frog
living in a trailer court alongside the area.
Broken glass everywhere.
