Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red Alder / Arroyo Willow Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest association is currently only known from Point Reyes National Seashore in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands are found on low-gradient streams and their banks, including upper terraces. Soil textures range from moderately fine sandy clay loam to medium sand of gravelly alluvium. All stands inventoried occur along permanent streams. Stands of this forest form an open herb layer, an open to continuous shrub layer, and an open to continuous tree layer. It is dominated by either Alnus rubra or Salix lasiolepis. However, either species must be at least 25% relative cover. Rubus ursinus and Urtica dioica are also present. A variety of other species may include Artemisia douglasiana, Carex sp., Ribes sp., Equisetum sp., Rumex crispus, Veronica americana, Lonicera involucrata, Acer negundo, Rubus armeniacus, Scirpus microcarpus, Polygonum sp., and Vinca major.

Geographic Range: This association is only known from the Point Reyes National Seashore. Information about its global characteristics is not available without additional inventory. However, it is likely that this type occurs along the central and north coast of California and perhaps farther north into Oregon and Washington.
