The traps were set in depressions. 1971 3.9 mi N, 1.8 mi E Castaic, Los Angeles Co., Calf... March 27 Want to above locality to look for ll cats Keith Murray reported. Found site to be in middle of new Castaic Dam. The reported site is now in the backer of the Dam, and there is no way to reach it. I went down a dirt road behind the dam, but it was washed out 1/2 way down the canyon. Habitat was Yucca + Sage in hills west of Dam, Yucca, Sage and Adenostoma Chaparral to the East. Typical Oryzomyx agilis country. March 27 Santiago Road, 1/2 mi S antelope Valley freeway, Los Angeles Co, Calif. Drove home from Castaic, arrived at 6:25 PM, sun down, I set out 48 10" Sherman's using Harvest food as bait. Couldn't see holes so I set most traps at the base of California Jumppers. Next morning we caught about 8-10 Peromyscus monacris in juvenile plumage- and perhaps 1. Brongysus trees?? Also got 1 Cottontail rabbit, 1 Perognathus longimembris and 3 Dipodomys peninsularis antonensis. Weather was very mild, and the moon set about 7:00 PM; an ideal night to trap. Heard Western Meadowlark and California Quail at night. The Yucca do not seem to be in flower this year, as they were 2 years ago. I suspect that I could have got more leporid if I had set by holes. Saw 1 creosote bush!
