Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Lodgepole Pine / Oval-leaf Blueberry Treed Bog

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This plant association occurs on peatlands in southeastern Alaska from sea level to alpine. The topography includes broken mountain slopes, hillslopes, and, most frequently, lowlands. The soils are very poorly drained and consist of deep organic material. The overstory averages 50% cover and is dominated by Pinus contorta var. contorta. Tsuga heterophylla, Tsuga mertensiana, Thuja plicata, and Callitropsis nootkatensis are common codominants and also common in the understory. Tall-shrub cover averages 40% dominated by Vaccinium ovalifolium and Menziesia ferruginea. Low shrubs are also abundant, including Vaccinium vitis-idaea and Ledum groenlandicum. Herbaceous cover averages over 40% and includes Cornus canadensis, Lysichiton americanus, Nephrophyllidium crista-galli, Carex pauciflora, Carex aquatilis var. dives, and Carex anthoxanthea.
