May 29 Put 42 traps on knoll in Freeway at Orinda Crossroads [called Orinda Island]. This is about 3 acres of grass & weeds, 3 high tension towers, and some periwinkle on one edge. Oats, rye grass, mustard, thistle, fat-tails, a few Baccharis bushes, numerous mouse grass cuttings, a few droppings, but no good clear runways. The vegetation very thick and obviously way afraid of the mice. Saw 1 Sclerophrys; squashed in the road nearly a mole and a big Sceloporus. May 30 Traps held 10 mice, 2 Ratter, and 4 mus. Tagged and released all species! worked mice (1135-1148) June 3 At 4pm put 72 Sherman alternate sites on Orinda Isld. Lots of runways, whitevine, droppings etc. dunny. The pasture vegetation is very poor. Large expanses of thistle with very little grass, and large expanses of cornus. The grazed places are on the top of the knoll where the soil is shallow and sandy. During the past 5 or more years there has been a steady plant succession from grass to mustard to cornus.
