CEGL005568 Pseudotsuga menziesii - Tsuga heterophylla / Polystichum munitum - Oxalis oregana Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir - Western Hemlock / Western Swordfern - Redwood Sorrel Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This Douglas-fir - western hemlock forest of Washington, Oregon and California has a canopy typically codominated by Pseudotsuga menziesii and Tsuga heterophylla. Tsuga heterophylla dominates tree regeneration. The shrub layer is rather sparse to moderate. Acer circinatum often forms a prominent tall-shrub layer. Mahonia nervosa and Vaccinium parvifolium are usually present and occasionally prominent. The well-developed herb layer is codominated by Polystichum munitum and Oxalis oregana. This association occurs at low elevation on lower slopes or valley bottoms with moist but well-drained soils.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This type is distinguished from similar associations by the presence of Pseudotsuga menziesii and Mahonia nervosa, and the lack of Blechnum spicant and Vaccinium alaskaense.
