CEGL003360 Pinus monticola / Ledum groenlandicum / Sphagnum spp. Treed Bog

Type Concept Sentence: No Data Available


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

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association is found in bogs or poor fens in the central and northern Puget Lowlands of Washington. Soils are wet to saturated and composed of sphagnum, fibrous and heath peat with woody material. The association is dominated by Ledum groenlandicum, which forms a tall semi-open to dense shrub layer. Spiraea douglasii is also present consistently in smaller amounts. Known existing examples have a scattered tree layer of 10-30% cover of Pinus monticola, though historically there were probably many woodlands. The moss layer generally has 20-90% cover of Sphagnum spp.
