Description: This California woodland alliance of valley bottoms and gentle slopes requires intermittently flooded, seasonally saturated soils. The soils are deep and alluvial or residual, and the water must be fresh. Elevations range from sea level to 775 m. The climate regime throughout the range of this alliance is strongly Mediterranean, with cool, moist winters and warm, dry summers. Most precipitation falls as rain between November and April. Yearly rainfall totals average approximately 60 cm. Stands of this woodland are dominated by ~Quercus lobata$. Other trees in the canopy may include ~Quercus kelloggii, Quercus douglasii, Quercus agrifolia, Platanus racemosa$, and ~Fraxinus latifolia$. Occasional shrubs may include ~Frangula californica ssp. californica$, and ~Toxicodendron diversilobum$. Lianas, such as ~Vitis californica$, are common. Annual grasses dominate the ground layer.
