Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Beach Pine / Bog Labrador-tea / Peatmoss species Treed Bog

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association is reported from British Columbia and Washington. The open woodland tree canopy is dominated by Pinus contorta var. contorta. Tsuga heterophylla or Thuja plicata may also occur in smaller amounts. The well-developed shrub layer is dominated by Ledum groenlandicum, or codominated by that species and Gaultheria shallon or Kalmia microphylla. The herb layer can be sparse to moderately dense and often has abundant Pteridium aquilinum. A well-developed moss layer is often dominated by Sphagnum spp. that is always at least present. This association occurs at low elevations in western Washington. Sites are bogs or poor fens with saturated peat soils and acidic, nutrient-poor conditions. Topography is typically flat basins or depressions.
