CEGL005166 Pinus banksiana - (Picea mariana) - Mixed Hardwoods / Sphagnum spp. Swamp Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Jack Pine - (Black Spruce) - Mixed Hardwoods / Peatmoss species Swamp Forest

Colloquial Name: Jack Pine Swamp Forest

Hierarchy Level:  Association

Type Concept: This jack pine swamp community is found in the upper Great Lakes region of the United States and Canada. Stands are found on poorly drained lowland sites, including those on sand plains. This type appears to originate following a catastrophic burn in a Picea mariana swamp. The canopy is dominated by Pinus banksiana with varying amounts of Picea mariana. The shrub layer is dominated by ericaceous shrubs, including Chamaedaphne calyculata, Gaultheria hispidula, Ledum groenlandicum, Vaccinium angustifolium, and Vaccinium myrtilloides. Abies balsamea and Picea mariana may also occur in scrub form in this layer. Herbaceous species include Clintonia borealis, Coptis trifolia, Cornus canadensis, Maianthemum canadense, Maianthemum trifolium, and others. The moss layer contains a variety of Sphagnum spp. and feathermosses.

Classification Comments: This type is being proposed by Michigan NFI (meeting 11-12 January 1996). It is found in Michigan on poorly drained sand plains in the northern Lower Peninsula. Pinus resinosa may also dominate some stands. Stands resembling this type were also reported in Wisconsin, by Curtis (1959, pp. 223-224) and by E. Epstein (central sand plains of Jackson County and scattered localities in Bayfield County) and in Ontario by Sims et al. (1989, NWV36, footnote). Apart from the canopy, this type may essentially resemble a poor black spruce swamp (e.g., ~Picea mariana - (Larix laricina) / Ledum groenlandicum / Sphagnum spp. Swamp Forest (CEGL005271)$$).
