Pinus rigida / Corema conradii Woodland
Reference:
NatureServe Biotics 2019
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 <i>Pinus rigida</i> (<i>Pinus banksiana</i> is dominant in one northern occurrence). Associated canopy species of low cover include <i>Quercus rubra, Betula papyrifera, Picea rubens, Pinus strobus, Abies balsamea, Acer rubrum</i>, and occasionally <i>Thuja occidentalis</i> or <i>Tsuga canadensis</i>. A low-shrub layer is characterized by <i>Corema conradii, Vaccinium angustifolium, Gaylussacia baccata, Aronia arbutifolia, Aronia melanocarpa, Morella pensylvanica, Kalmia angustifolia, Comptonia peregrina, Viburnum nudum var. cassinoides</i>, and <i>Vaccinium pallidum</i>. <i>Corema</i> is diagnostic. Other associated herbs and dwarf-shrubs include <i>Juniperus communis, Arctostaphylos uva-ursi, Deschampsia flexuosa, Danthonia spicata, Gaultheria procumbens, Melampyrum lineare, Solidago puberula, Trientalis borealis, Maianthemum canadense, Epigaea repens, Sibbaldiopsis tridentata</i>, and <i>Carex deflexa</i>. Lichens and mosses include <i>Cladina</i> spp., <i>Cladina stellaris</i> and other <i>Cladonia</i> spp., <i>Polytrichum piliferum, Polytrichum juniperinum, Leucobryum glaucum, Hylocomium splendens</i>, 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.
