Christmas 1959 Journal 137 14 Mar. Solano County, Calif. Vallejo - Dixon Hwy 40 Left Berkeley at 11:am. (55696.5) via Hwy 40. The hills east & NE of Vallejo are about 95 % grass with Eucalyptus in groves and in few rocky areas live oaks though all are small, over ridge about 15 oaks (all live) and in relation to the drainage ways where stream is lined with dense willow now almost fully leafed out. The valley here - at Rockville & Green Valley Creeks (55727) is part of a flat & old tidal plain - hills are woodlands from fairly open to closed, up the Canyon to N. woodland - grass to chaparral - woodland. The lower slopes of hills here appear to be parkland. A few remnant oaks of Residuous sp. are evident: 12 noon. Boxboxes seem to be mixed in with the oaks in this valley. 55733 - Turn off to Travis AFB. The W. end of this valley is orchards with a few reminent deciduous oaks and Baccharis growing at side of road & disturbed areas as rock cuts, from here - the hills to S. are lean & woods hill by the road are grassy with old willows in streams - hills grow. The oak woodlands are much further up the hill to the north. Vacaville: Coming over the ridge into Vacav, the woodland was much denser on E. slope - was rolling and immediately gave way to the plain. The road side Baccharis gave way. From NE of Davis the country was dry type pasture with sheep. About three were few areas of orchards. About the only trees were Eucalyptus hardly anything else - many old sites of ranches with cypress, etc.
