Name:
Pinus rigida Saturated Woodland Alliance
Reference:
Eastern Ecology Working Group of...
Description:
Communities of this alliance are characterized by an open canopy of Pinus rigida, with an understory of ericaceous shrubs over a mat of Sphagnum moss. These wetlands are "boggy" in nature, generally with saturated acidic soils and extensive peat accumulation. They form in poorly drained depressions or deeper basins, interdunal swales, and on stream flats (not flooded except in very rare events), and sometimes have a floating bog mat. Canopy associates of this alliance include Acer rubrum, Nyssa sylvatica, and Betula populifolia. The shrub layer may be dominated by Chamaedaphne calyculata, or made up of Vaccinium corymbosum, Rhododendron canadense, Kalmia angustifolia, Gaylussacia baccata, or Gaylussacia frondosa (= var. frondosa). The herbaceous stratum is generally characterized by Eriophorum virginicum, Calopogon tuberosus, and Scirpus spp. Northern occurrences may contain Scheuchzeria palustris, Gaultheria procumbens, Vaccinium macrocarpon, and Cornus canadensis, while woodlands in the southern part of the main range support species such as Orontium aquaticum, Lophiola aurea, Arethusa bulbosa, Helonias bullata, Xyris spp., Xerophyllum asphodeloides, Gentiana autumnalis, Muhlenbergia torreyana, and Calamovilfa brevipilis. In the Southern Blue Ridge, Kalmia carolina, Toxicodendron vernix, Gaylussacia baccata, and Symplocarpus foetidus are components. In the New Jersey pine barrens, additional species include Leiophyllum buxifolium and Polygala lutea. This alliance occurs in the pine barrens of New Jersey, southern New England, and in the southern Blue Ridge of North Caroliana. This alliance is of very limited occurrence in the southeastern United States; it is more widespread farther north.
