April 12 Valencia Sagoon, Rio del Mar and vicinity, Santa Cruz Co., Calif.
Left Albany Village at 7:20 am with Steve Lynch. Drove in a Eastshore Freeway to San Jose, then Rt 9 to Santa Cruz. Hwy 1 to Rio del Mar. Worked Valencia Sagoon for larvae, collecting 30 in about 1 hour of dip netting. Fog present - did not lift until 11:00 am. The pond has dried considerably since March 30. The west end of the pond has receded 8-10 yards. The good Eleocharis areas are almost dry. The water level has dropped 6" or so. Pond will dry by May at this rate unless there is more rain. Larvae now are concentrated about clumps of Polygonum with water 1-3" deep at least in Eleocharis mats usually fragmented. We worked out in deeper water - 15-20" deep but got only 2 larvae. Water still murky from silt & difficult to see into. 2 pairs of Mallows, 1 pair Cinnamon Teal + a single coot seen on pond. This is first time I've seen Cinnamon Teal at Valencia. Left Valencia at 11:15 to head towards Ellicott. Picked up 2 Coluber constrictor morrison + 1 Psitrophis coterifer under boards at SE end of pond area. Drove to the Liger Pond 1 mi NW Ellicott RR Sta, 4 mi W Watsonville, Santa Cruz Co., Calif. Found it completely dry - all amphibians failed to make it through the aquatic stages. Next drove to "Ellicott Pond" and worked it 1/4 hr for larvae. Got just 2 Cymbistoma m. creemum larvae. Turned logs in willow clump & got 2 adult creemum. Ate lunch at 2:15 pm and spent rest of afternoon snake hunting about 1 mi NW Ellicott RR Sta. Got
