Name: Kalmia angustifolia - Ledum groenlandicum Dwarf-shrubland Alliance
Reference: Eastern Ecology Working Group of...
Description: This alliance contains alpine and boreal dwarf-shrublands and other communities known as "boreal heathlands," characterized by a very open canopy of black spruce, generally at high elevations and on acidic bedrock. The canopy is characterized by stunted and widely spaced Picea mariana, sometimes in association with Picea rubens, Betula papyrifera var. cordifolia (= Betula cordifolia), Sorbus americana, and Abies balsamea. The shrub layer, characterized by ericaceous species such as Ledum groenlandicum, Kalmia angustifolia, Vaccinium vitis-idaea, Vaccinium uliginosum, Rhododendron canadense, as well as Empetrum nigrum, is generally quite dense, but may be patchy and interspersed with expanses of bare or lichen-covered bedrock. Herbaceous species, such as Paronychia argyrocoma (= var. albimontana) and Juncus trifidus, are usually confined to crevices. This alliance occurs at high elevations, usually just above tree line, in Maine, New Hampshire, Vermont, and New York. It is also likely to occur in Canada.
