CEGL002615 Pseudotsuga menziesii - Tsuga heterophylla / Rhododendron macrophyllum - Vaccinium ovatum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir - Western Hemlock / Pacific Rhododendron - California Huckleberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs below 460 m (1500 feet) elevation in west-central portions of the Puget Lowland of Washington, including the Kitsap Peninsula, Whidbey Island, and the northeastern Olympic Peninsula (Mason, Kitsap, Island, Jefferson, Clallam counties). This is an evergreen needle-leaved forest dominated by Pseudotsuga menziesii and Tsuga heterophylla, the former usually taller and more abundant, the latter usually dominating tree regeneration. Thuja plicata is usually present and sometimes codominant, and Pinus monticola is present in about half the plots. The understory is dominated by the evergreen broad-leaved shrubs Rhododendron macrophyllum (2-4 m tall), Vaccinium ovatum, and Gaultheria shallon, and may be sparse or dense depending on tree density. Other frequent species are Pteridium aquilinum, Mahonia nervosa, and Vaccinium parvifolium. Herbaceous species are typically found in very small amounts. This association typically occurs on moderately dry, very nutrient-poor sites including soil parent materials of gravelly glacial till or outwash, or basalt bedrock. This association is distinguished from similar ones by >10% cover of Tsuga heterophylla or Thuja plicata, >5% cover of Rhododendron macrophyllum, and the presence of Vaccinium ovatum, combined with <3% cover of Polystichum munitum.
