Pinus rigida / Vaccinium myrtilloides / Sphagnum spp. Swamp Woodland
Translated Name: Pitch Pine / Velvetleaf Huckleberry / Peatmoss species Swamp Woodland
Common Name: Pitch Pine / Huckleberry Peat Swamp Woodland
Unique Identifier: CEGL006022
Classification Approach: International Vegetation Classification (IVC)
Summary: This northern pitch pine swamp occurs in poorly drained depressions in sand plains of the Great Lakes plain in New York. An impermeable soil horizon formed by iron oxide impedes drainage in areas of the sand plain allowing peat accumulation. The dominant tree in the open canopy is Pinus rigida. Common tree associates include Betula populifolia and Acer rubrum. The shrub layer is well-developed, dominated by Vaccinium corymbosum. Lesser amounts of Kalmia angustifolia and Aronia melanocarpa also make up the shrub layer, along with shrubs of more northern distribution, Vaccinium myrtilloides and Viburnum nudum var. cassinoides. The herb layer is made up of Gaultheria procumbens, Cornus canadensis, Pteridium aquilinum, and Maianthemum canadense. Sphagnum mosses make up the bryophyte layer. Although related to pitch pine swamps of pine barrens in the northeast and New Jersey, the presence of the northern species, Vaccinium myrtilloides, Viburnum nudum var. cassinoides, and Cornus canadensis, differentiates this type from its relatives in the alliance.

NatureServe Conservation Status
Global Status: G1G2 (09Nov1998)
Rounded Global Status: G1 - Critically Imperiled
Reasons: This community is restricted to areas of impeded drainage within northern sandplains. Only one occurrence is currently documented, but there may be others in sandplains of northern New England. The likelihood of the discovery of many new occurrences is low, however, as the habitat and range of this type are naturally restricted.
