Caywell 1949 Journal 77 French Camp, 3100 ft., Humboldt Co., Calif. Aug. 22 (cont.) covers the upper slopes of this ridge from the crest at 2300-2460 ft. down the SW facing ridges as low as 1500 ft. Douglas Fir forest reaches nearly to the top of the ridge on the NE facing slope and also in canyons on the SW facing slope. The forest extends across the ridge top at a point some 3 mi. NW of Schoolhouse Peak, beyond which lie other smaller but similar prairies which I did not visit. The oak woodland is mostly of Quercus garryana and is found on the steepest SW facing slopes and up to the ridge crest in only a few places. It extends across the road in a broad belt W & NW of Schoolhouse Peak. The habitats worked in or near, then, included (1) dry grass & stubble fields; (2) Barry Oak woodland, with understory of Pinus diversifolia and Purshia sp. in some places, and (3) Douglas Fir forest. After leaving Dr. Pearson & Murray on the S slope of Schoolhouse Peak, I drove to the NW end of the largest prairie which is about 3 mi. from the peak. The area labelled "Childs Hill Prairie" on the U.S. War Dept Coyote Creek quadrangle topog. map (1:62500; 1945) was crossed in a series of loops from the road. Most of the fields here have been recently mowed, & most birds were concentrated in the unmowed borders or portions
