Name:
Vaccinium (angustifolium, myrtilloides, pallidum) - Cladonia rangiferina Dwarf-shrubland
Reference:
NatureServe Biotics 2019
Description:
These blueberry barrens, known from scattered locations in the Adirondacks, northern Maine, and Downeast Maine, occur on flat or undulating glacial outwash or till plains, sometimes as openings within wooded barrens. The soils are sandy, acidic, and very nutrient-poor. Where the substrate contains an impervious subsoil layer, the natural undulations in the substrate result in a pattern of upland and wetland pockets in an intimate network. Dwarf-shrubs are the dominant plants. Widely scattered trees may be present, but overall tree cover will be under 20%. Herbs are scattered among the blueberries, rarely totaling more than 25% cover. The bryoid layer may be extensive and is usually dominated by lichens. One or more lowbush blueberry species are the dominant shrubs: <i>Vaccinium angustifolium, Vaccinium myrtilloides</i>, or <i>Vaccinium pallidum</i>. Minor shrubs include <i>Aronia melanocarpa, Spiraea alba, Kalmia angustifolia, Comptonia peregrina</i>, and <i>Lonicera villosa</i>. <i>Piptatheropsis canadensis, Piptatheropsis pungens</i>, or <i>Oryzopsis asperifolia</i> are characteristic herbs, although rarely abundant. Other herbs include <i>Pteridium aquilinum, Solidago canadensis, Euthamia graminifolia, Lycopodium dendroideum</i>, and <i>Lycopodium digitatum</i>. <i>Cladonia rangiferina, Cladonia stellaris</i>, and <i>Cladonia pyxidata</i> are common lichens; mosses include <i>Polytrichum juniperinum, Polytrichum commune, Polytrichum piliferum</i>, and <i>Pleurozium schreberi</i>. In the wetter pockets, <i>Sphagnum</i> mosses may be locally common. This association generally occurs in areas with a consistent fire history. Where fires have been particularly intense, lichens may form extensive carpets, sometimes termed "lichen barrens."
