Name: Alnus serrulata - Amorpha fruticosa Shrubland
Reference: Southeastern Ecology Working Gro...
Description: These alder - indigobush temporarily flooded riparian shrublands are found in the United States in the Ouachita Mountains of Oklahoma, Arkansas, and possibly Missouri. Stands occur near slow-moving water among the cobble bar vegetation of mountain streams. This community is maintained by the flashy, high-velocity flows and flooding of upland (often intermittent) streams. Dense piles of debris around the bases of the shrubs and aerial leaf packs ("alps") are common. Soils are derived from alluvial deposition of eroded sandstone, shale, and chert substrates. These shrublands are moderately tall (2-5 m [8-15 feet]) and often partially recumbent. <i>Alnus serrulata</i> is the dominant shrub. Associated shrubs include <i>Amorpha fruticosa, Amorpha nitens, Cephalanthus occidentalis, Cornus obliqua (= Cornus amomum ssp. obliqua), Cornus foemina, Hypericum prolificum, Ilex decidua, Itea virginica, Lyonia ligustrina, Styrax grandifolius, Vaccinium fuscatum, Viburnum nudum</i>, and others. Typical species in the herbaceous layer include <i>Amsonia hubrichtii, Dichanthelium dichotomum var. dichotomum (= Panicum microcarpon), Dichanthelium sphaerocarpon var. isophyllum (= Panicum polyanthes), Dulichium arundinaceum, Elymus virginicus var. virginicus, Gratiola brevifolia, Hypericum mutilum, Juncus effusus, Lysimachia lanceolata, Proserpinaca palustris, Ptilimnium nodosum</i> (restricted distribution), <i>Pycnanthemum tenuifolium, Rhynchospora capitellata, Solidago rugosa, Sium suave</i> (uncommon), and others.
