Name: Alnus viridis ssp. crispa - Spiraea alba / Solidago macrophylla Shrubland
Reference: Eastern Ecology Working Group of...
Description: These alder-birch shrublands are found in the subalpine to lower alpine zones of the higher mountains in the Northern Appalachians. They typically develop in somewhat unstable settings such as avalanche paths, old landslides, or cirque walls. The most common setting is on a steep, concave slope, although they may also occur on flats. Deciduous shrubs averaging 1-2 m tall dominate and may form thickets. Herb cover is best developed in openings among the shrubs, and so is patchy. Dwarf-shrubs are a minor component, and bryophytes are sparse. The dominant species are <i>Alnus viridis ssp. crispa</i> and <i>Betula papyrifera</i> (possibly including the subalpine var. <i>cordifolia</i>). <i>Diervilla lonicera</i> may be locally abundant, especially in somewhat drier microsites. Stunted <i>Picea mariana</i> and <i>Abies balsamea</i> may occur with the shrubs. <i>Viburnum edule</i> is often present, although in very low numbers. Herbs include <i>Solidago macrophylla, Prenanthes trifoliolata, Eurybia radula (= Aster radula), Sibbaldiopsis tridentata</i> (in drier openings), <i>Dryopteris campyloptera, Dryopteris intermedia, Athyrium filix-femina</i>, and <i>Calamagrostis canadensis</i>.
