Name: Quercus lobata Riparian Forest Alliance
Reference: NatureServe Biotics 2019
Description: This California riparian woodland alliance is dominated by <i>Quercus lobata</i>. Other trees in the canopy may include <i>Alnus rhombifolia, Fraxinus latifolia, Platanus racemosa, Quercus agrifolia, Quercus douglasii, Quercus kelloggii</i>, and <i>Salix</i> spp. Occasional shrubs may include <i>Frangula californica ssp. californica, Rubus armeniacus</i>, and <i>Toxicodendron diversilobum</i>. Lianas such as <i>Vitis californica</i> are common. Annual grasses dominate the ground layer. Stands occur in valley bottoms and on gentle slopes and require intermittently flooded, seasonally saturated soils. Soils are deep and alluvial or residual, and the water must be fresh. Elevations range from sea level to 1158 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.
