Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Lodgepole Pine / Sitka Sedge Treed Bog
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association occurs throughout southeastern Alaska where it is widespread on peatlands on flat to gentle slopes at less than 460 m (1500 feet) elevation. This is an open forest wetland with Pinus contorta var. contorta as the main overstory tree averaging 18 m (60 feet) in height, while Tsuga heterophylla, Tsuga mertensiana, and Picea sitchensis occur in a shrub-like growth form. Vaccinium ovalifolium, Menziesia ferruginea, and Vaccinium uliginosum are abundant shrubs. Lysichiton americanus and Rubus pedatus are common as is Carex aquatilis var. dives.

Classification Comments: First published description is for Chatham Area, Tongass National Forest (TNF) (Martin et al. 1995). Stands were also described for Stikine Area, TNF (Pawuk and Kissinger 1989), but not from Yakutat Foreland described by Shephard (1995). This association has been described throughout southeastern Alaska (Martin et al. 1995, Pawuk and Kissinger 1989, Shephard 1995). It is most similar to the Pinus contorta / Empetrum nigrum types described in southeastern Alaska by Martin et al. (1995), Pawuk and Kissinger (1989) and Shephard (1995).
