Some are predominantly chaparral soils while others are much better adapted to growing forest or grass. (3) Los Gatos stony clay loam; and (4) Dulzura stony sandy loam. The four dominant soil types of this group comprise about 13/4 million acres, or per cent of the State. Altogether, the "Ex" group of soils comprise about 25 per cent of the upland group. Over this entire area of lithosol soils chamise is the dominant vegetation, but species of manzanita are common on some of them. The Maymen and the Henneke soils are distinctly low in potential production chiefly because of their shallow phase. The Los Gatos and Dulzura soils are likewise low for grass production. En—Residual soils of medium to fairly shallow depth to bedrock. These are brownish soils of neutral, slightly acid or basic reaction, and are often referred to as Noncalcic Brown soils. The Vallecitos loam soil is one of the dominant soil types (drawing, above). These residual soils comprise ab
