Description: Stands of the Abies bracteata Forest Alliance (A.147) are found between 250 and 1400 m elevation in the central California Coast Ranges, most commonly near the crest of the range. Annual precipitation increases with elevation and totals approximately 80 cm, with a distinct summer dry season. This alliance occurs above the zone of summer fogs, and temperatures show more fluctuation than those at lower elevations. Stands are concentrated on steep, rough terrain that does not carry intense fire. Sites include rocky slopes, ridges, and canyons or ravines; slope aspects are typically northerly or easterly. Stands in ravines are found on stream benches or terraces, usually with concave topography and seasonally saturated soils. Soils in ravines are skeletal to deep, with loamy textures. On steep slopes and ridges the parent materials are sandstones and shales with overlying skeletal soils of various textures. These soils are well-drained and rocky. Abies bracteata is the sole, dominant, or codominant species in the canopy. The broad-leaved evergreen tree Quercus chrysolepis is important or codominant in most stands. Several other conifers, such as Pinus coulteri, Pinus ponderosa, or Pinus lambertiana, may be present. Broad-leaved evergreens, such as Arbutus menziesii and Lithocarpus densiflorus, are often present. Shrubs are infrequent, and the herbaceous layer is sparse.
