March 4 Left 3 p.m. with Green and Isaac for Marin Co.: looked at several of the Salicornia marshes near our last week's station but none seemed to have as many sign on the original site. Put traps at 1 new place and then re-covered 3 places where we had trapped before. Saw practically no really fresh droppings or cuttings. While setting saw 2 Toads, 1 Bufo, 2 Sceloporus, 11 spring-tailed snake, and a pair of Rites. Heard great horned owl and many frogs at dusk. Salicornia twigs very dry with practically no fleshy parts.
