Name:
Pinus rigida / Corema conradii Woodland
Reference:
Eastern Ecology Working Group of...
Description:
This pitch pine woodland community occurs primarily on near-coastal acidic rock outcrops of southern Maine. The open canopy of short and often twisted trees overlies a well-developed heath shrub layer. Herbs and tall shrubs are sparse. The bryoid layer is patchy, but may be well-developed, and lichens are prominent. The dominant tree is Pinus rigida (Pinus banksiana is dominant in one northern occurrence). Associated canopy species of low cover include Quercus rubra, Betula papyrifera, Picea rubens, Pinus strobus, Abies balsamea, Acer rubrum, and occasionally Thuja occidentalis or Tsuga canadensis. A low-shrub layer is characterized by Corema conradii, Vaccinium angustifolium, Gaylussacia baccata, Photinia pyrifolia (= Aronia arbutifolia), Photinia melanocarpa (= Aronia melanocarpa), Morella pensylvanica (= Myrica pensylvanica), Kalmia angustifolia, Comptonia peregrina, Viburnum nudum var. cassinoides, and Vaccinium pallidum. Corema is diagnostic. Other associated herbs and dwarf-shrubs include Juniperus communis, Arctostaphylos uva-ursi, Deschampsia flexuosa, Danthonia spicata, Gaultheria procumbens, Melampyrum lineare, Solidago puberula, Trientalis borealis, Maianthemum canadense, Epigaea repens, Sibbaldiopsis tridentata (= Potentilla tridentata), and Carex deflexa. Lichens and mosses include Cladina spp., Cladina stellaris (= Cladonia stellaris) and other Cladonia spp., Polytrichum piliferum, Polytrichum juniperinum, Leucobryum glaucum, Hylocomium splendens, and others. Scattered occurrences on sandy outwash deposits in Massachusetts and a single occurrence in the Shawangunk Mountains of New York are also classified as this type.
