Triturus torosus
Boulder CA, 7.5 mi NNW Descanso
San Diego Co. Calif.
Reached here at about 10:00 AM, DST. Two Tritura were taken immediately and several thus seen which are out of reach. Here the stream is about 20' wide and, at maximum,
1' deep. This is a relatively still region about
60' long with more rapidly moving water on
a rocky streamlbed at either end. Water
temperature 17.0°C
A total of 12 Tritura were collected - 10
to send to Reine and 2 for the native doc.
They were very abundant. For example, in
the pool from which the last one was collected,
there were at once twelve others in sight.
Some of the pools in which Tritura were
seen are 3 feet deep. There is much more water
than last year. At this time last year there
were places on the stremlbed with no water
at all.
Aug: 25, 1952
Rereited some spot, but no salamanders.
Do they wait for the summer thunderstorms
to leave the water? There is as much
water now as there was in June.
