Hafner m.s. 1973 Journal 30 Dec. 3:00 PM. - Tijunga Canyon, approx. 10 mi. N.E. of Sunland - near tree farm on hill to right of road past big bridge 1/4 mi. (new road marker "7.43", Los Angeles Co. Calif. 2500). John Hafner, Kevin & Kenny Ramsey and I set 120 live traps and 150 snap traps in same local as Set #4 of 28 Dec 1973. This is the locality I had caught Dipodomys agilis. Slight uphill grade, varying from sparse Odonostoma (sp.) community to more lush growth (all bushes) in area immediately N. of young grove of pines planted perhaps 15 years ago. Ground shows much evidence of recent (5-10 yrs) ago fire. Area in which Dipodomys caught somewhat less dense in vegetation than surrounding vegetation. 31 Dec.

Checked traps: 10 Dipodomys agilis 1 Microtus (californicus) ? 18 Peromyscus sp. 16 Neotoma fuscipes Success: 35/270 = 13% John reported seeing evidence of (Tree) squirrels in adjacent pine grove [all specimens given to Texas Tech.
