Location Narrative	This is a mature stand dominated by multi-stemmed Quercus wislizeni and Pinus sabiniana (dbh: 20-30 cm). Understory consists of sparse Quercus douglasii with abundant Heteromeles arbutifolia and Arctostaphylos viscida. Herb layer is sparse. Multi-stemmed Quercus wislizeni and even age of stand suggest a disturbance within the past 100 years.
