CEGL002614 Pseudotsuga menziesii - Tsuga heterophylla / Vaccinium ovatum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir - Western Hemlock / California Huckleberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs below about 300 m (1000 feet) elevation in central portions of the Puget Lowland of Washington, and in portions of the Gulf Islands, British Columbia. This is an evergreen needle-leaved forest typically 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 occasionally codominant; Pinus monticola is present in about half the plots, and Pinus contorta is occasionally prominent in young stands. The well-developed 0.8- to 2.0-m tall understory is dominated by the evergreen broad-leaved shrubs Vaccinium ovatum and Gaultheria shallon. 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 slightly dry to mesic, nutrient-poor sites, mainly on gravelly glacial till. This association is distinguished from similar ones by >10% cover of Tsuga heterophylla or Thuja plicata, and >5% cover of Vaccinium ovatum, combined with <5% cover of Rhododendron macrophyllum and <3% cover of Polystichum munitum.
