CEGL003201 Pinus contorta / Sphagnum spp. Treed Bog
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Lodgepole Pine / Peatmoss species Treed Bog
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association is found primarily on peat averaging 90 cm (35 inches) thick. It occurs on the oldest deglaciated landscapes of the Yakutat Forelands, Alaska, including kettle-kame topography and in small scattered stands on distal outwash and uplifted tidal flats. Pinus contorta var. contorta dominates this woodland type and varies from 3-12 m (9-40 feet) tall and 7-35 cm (3-14 inches) in diameter. Downed logs are uncommon. Limited regeneration is common for Picea sitchensis and Tsuga heterophylla, and only Pinus contorta var. contorta grows to tree height. Subshrubs, such as Empetrum nigrum, Vaccinium oxycoccos, and Ledum groenlandicum, are common. Typical herbaceous species are Cornus canadensis, Sanguisorba menziesii, Carex aquatilis var. dives, and Trichophorum cespitosum. Sphagnum species dominate the moss layer.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is described from the Yakutat Foreland in Alaska (Shephard 1995). This association is similar to other Pinus contorta var. contorta associations described by DeMeo et al. (1992) and Martin et al. (1995) for southeastern Alaska.
