J.D. Anderson 1958 Journal June 20 Valencia Lagoon, Rio del Mar, Santa Cruz Co., Calif Left Allany at 5:45 am + arrived at Rio del Mar at 7:30 am. The dirt roads skirting the lagoon + the oak woods have been fixed after the long drying out period following heavy damage this winter. Personally I wish they wouldn't touch them. Road around pond (Bayite Dr.) was not bothered much - some holes filled. The road into the hill area was worked on by a grader + widened a little although they seem not to have cut any trees. Some brush which had accumulated was pushed aside but no major disturbance. The pond has shrunk considerably since 31-May. Main area of water restricted to immediately in front of large willow to edge of forest (Forest) Ernest willow clumps - see map. Pattern of recession essentially as in 1956. Began dip net work for larval sample at 8:15 am. Got 5 large larvae by 9:10. Returned to car to transfer these to gallon jars. Worked again with net between 9:30-10:30 am. Got only 3 more larvae; making 8 in 110 min. Tadpoles are way down in number. Newly metamorphosed (Hyla) are everywhere around edges. Every leaf + grass blade seems to have its tiny tree frog. Saw 3 or 4 newly metamorphosed Rana aurora, also caught several in dip net with 4 legs + partly absorbed tail. Still quite a few aurora tadpoles which have no legs. Belastmatite extremely abundant. Most are
