CEGL003173 Sequoia sempervirens - Pseudotsuga menziesii Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Redwood - Douglas-fir 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 at low elevations on the mid third to entire side of 14° to 34° slopes. Aspects are southeast to southwest. Soil textures range from moderately fine sandy clay loam to medium to very fine sandy loam of Franciscan Melange. Stands of this forest form an open ground layer, an open to intermittent shrub layer, and an intermittent to continuous tree layer. This association is dominated by Sequoia sempervirens and Pseudotsuga menziesii, and Umbellularia californica and Notholithocarpus densiflorus are also present. Understory species may include Corylus cornuta, Polystichum munitum, Iris douglasiana, Lonicera hispidula, Maianthemum sp., Galium sp., Pteridium aquilinum, Stachys ajugoides, Toxicodendron diversilobum, Quercus sp. and a variety of other understory species. This association may be differentiated from ~Sequoia sempervirens / Notholithocarpus densiflorus / Vaccinium ovatum Forest (CEGL003172)$$ by the presence of tree-sized Pseudotsuga menziesii and the general absence of Vaccinium ovatum in the understory.
