Journal Nafner, M.S. 1976 0.8 mi. N, 6 mi. W Lost Hills, 500 ft, Kern Co., California April 1000 Dacey, Emily, Baron and D departed Richmond in the Van and drove S on 580 via Oakland, Livermore and I-5 to a point 8 mi N and 3.5 mi W of Lost Hills. [The purpose of this trip is to collect Dipodomys nitratoides for the Fish & Game survey.] We drove about 0.5 mi W on Twisselman Rd. and set 60 live traps just N of the road. [The habitat will be described below (see 10 April)]. The sky was clear; warm day (~70°) with a light Wly breeze. I heard the "chirps" of Ammospermophilus at this locality. We then drove E on Twisselman Rd toward the Kern Nat. Wildlife Refuge. After about 1/2 hour on levee roads we arrived at the NW corner of the refuge. The habitat within the fence was fairly suitable Dipodomys habitat. — not especially promising. We continued S along the Western edge of the refuge and then turned E along the Southern edge. Found no suitable habitat outside the refuge until almost 1 mile from the main highway that forms the Eastern border of the Refuge. (Little or no good Dipodomys habitat within the Refuge). We set out 60 traps about 1 mi. from the road on the Southern border of the Refuge, then drove to the Highway (= Corcoran Road). We drove North along the Eastern edge of the Refuge and then W along the Northern
