Devil's Basin Research Natural Area Establishment Record

Overlooking the perennial Thomes Creek, on the north slope of Log Springs Ridge, the Devil's Basin Research Natural Area (DBRNA) covers an area of 671 acres (272 hectares) and is centered around a large flat on the toe of an old land failure. The area features a diverse mixture of vegetation types, including: black oak woodland, Coast Range mixed conifer forest, blue oak woodland, canyon live oak forest, and northern mixed chaparral. Within the DBRNA, California black oak can be found in a continuum of stages, from a large, persistent sub-climax stand to non-persistent seral stands of black oak forests or mixed evergreen forests.
