Name: Pinus rigida - Quercus ilicifolia - Rhododendron canadense Woodland Reference: NatureServe Biotics 2019 Description: This mesic pine barren community is restricted to the eastern portion of the High Allegheny ecoregion. Unlike all other pine barrens associations that occur in xeric habitats, this association occurs on deep, fine-loamy Illinoisan till. The origin of this association is not known definitively, but there is much evidence to suggest that that this community has likely persisted in this environment as a result of frequent fire. The canopy is dominated by <i>Pinus rigida</i>, with <i>Acer rubrum</i> as a common associate. The understory is characterized by <i>Quercus ilicifolia</i>, with associated heaths <i>Vaccinium angustifolium</i> and <i>Kalmia angustifolia</i>. <i>Rhododendron canadense</i> is the most characteristic shrub of this association. The herbaceous layer is characterized by <i>Pteridium aquilinum, Calamagrostis coarctata, Carex pensylvanica, Patis racemosa</i>, and <i>Rubus hispidus</i>. Other associates include <i>Amianthium muscitoxicum, Doellingeria umbellata</i>, as well as the rare plants <i>Carex polymorpha</i> and <i>Lygodium palmatum</i>. The mesic soil conditions and presence of <i>Rhododendron canadense, Carex polymorpha, Amianthium muscitoxicum, Lygodium palmatum</i> differentiate this association from other related associations in this alliance.  Accession Code: urn:lsid:vegbank.org:commConcept:34805-{909557D9-F915-4060-A651-AFCD4575AF66} Plot-observations of this Community Concept: 0
