Name: Sequoia sempervirens Forest Alliance
Reference: NatureServe Biotics 2019
Description: This alliance consists of forests where <i>Sequoia sempervirens</i> is the dominant tree with few other tree species in the canopy, but <i>Abies grandis, Acer macrophyllum, Alnus rubra, Arbutus menziesii, Chrysolepis chrysophylla, Notholithocarpus densiflorus, Picea sitchensis, Pseudotsuga menziesii, Tsuga heterophylla</i>, and <i>Umbellularia californica</i> may be present. Trees are less than 120 m tall, and the canopy is partly open to continuous, with two or more tiers. Shrubs are infrequent or common. Herbaceous layer is absent or abundant. Fire is the principal disturbance agent in both young and old-growth stands. Fire-return interval is variable depending on environmental site conditions. Old-growth stands show up to three or more severe fires per century, with several short intervals followed by one or more long intervals. Short fire intervals may be as frequent as 6-27 years. This alliance occurs on raised stream terraces and benches from 10-975 m elevation. Stands occur in moist coastal areas with heavy summer fog, generally below 600 m in elevation from southern Oregon to Santa Lucia Mountains in central California.
