J.D. Anderson 1959 Journal Jan 21 Valencia Sagoon, Rio del Mar vicinity, Santa Cruz Co., Calif. Left Berkeley at 8:30 am with P. Crippen. Drove to Santa Cruz via Rt 17. Short stop for photo equipment in San Jose. Arrived Rio del Mar at 10:45. Pond still at maximum size. Shoots of Eleocharis comes up at edge - not yet tall enough to come above surface of water. Polygonum not grown's as yet. Worked N end of pond for Ambystoma eggs. Found them in fair number (see sp. accounts A.m. microsum for details). Checked entire N. half of the pond & found eggs in shallow water whereas there was a clump of Eleocharis. Checked around Polygonum but saw no eggs attached to it though 2 yards from clumps of Polygonum there were many eggs on Eleocharis. Next drove to "Tiger Pond", 1mi N W Ellicott Rd Sta, Ymca: W Watsonville. The small pond (see Jan 10 note) was completely dry. That is other was no standing water, some 2 puddles less than 1ft across. Any holes dug into substrate filled with water, so it won't take much to re-fill this pond. Hyla regilla had bred while there was water and hundreds of egg masses were destroyed when pond dried. It will be interesting to follow this pond thru the season to see what effect this premature breeding has on populations of Hyla and Ambystoma tigrinum. Drove to "Ellicott Pond" next. Worked around edge & picked up about 20 eggs of Ambystoma. Hyla masses quite abundant. Water very smelly here. No sign of adult or larvae. Vegetation just beginning.
