R. Zweifel July 28, 1951 Paso Robles Camp, Cuyamaca Ranchos State Park, San Diego County, Calif. 251 Description of the camp and surroundings The camp area lies at an elevation of about 4800 feet and includes both meadow and lower Transition Zone forest. The meadow area is covered with a thick growth of grasses, many of them non-native species. Yarrow and milkweed (Asclepias eriocarpa) are common in all open places, both in the meadow proper and in the forest where there are smaller grassy patches. In the campground proper, the dominant tree species are black oak (Q. kelloggii), incense cedar (Libocedrus decurrens) and Jeffrey pine (Pinus ponderosa jeffreyi). Coulter pine (Pinus coulteri) and canyon oak (Q. chrysolepis) are also present, but are not so prominent locally in the camp area as elsewhere in the park. Coffeeberry (Rhamnus), chokecherry (Prunus demissa), mountain lilac (Ceanothus palmeri) manzanita (Arctostaphylos) and squaw bush (Rhue trilobata) are the more prominent shrubs. In places the manzanita forms extensive thickets which are favored by the Cnemidophorus. The soil is all granitic, although where black oaks are prominent, a rich humus forms.
