Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Atlantic White-cedar / Great Laurel Swamp Forest
Colloquial Name: Atlantic White-cedar / Great Laurel Swamp Forest
Hierarchy Level: Association
Type Concept: This saturated peatland forest is dominated by Chamaecyparis thyoides with a dense shrub layer dominated by Rhododendron maximum. It occurs in southern New Hampshire, Massachusetts, southern Rhode Island and Connecticut, southeastern New York and northern New Jersey. Associated canopy trees may include Acer rubrum, Betula alleghaniensis, Tsuga canadensis, or Nyssa sylvatica. Associated shrubs are generally few and of low cover but may include Kalmia latifolia, Vaccinium corymbosum, Rhododendron viscosum, Ilex verticillata, Nemopanthus mucronatus, and Kalmia angustifolia. The herbaceous layer is generally sparse due to the dense shade cast by shrubs, but may include Trientalis borealis, Carex collinsii, Osmunda cinnamomea. Typical Sphagnum mosses include Sphagnum magellanicum, Sphagnum fallax, Sphagnum fimbriatum, Sphagnum russowii, Sphagnum recurvum.
