Name: Alnus serrulata - Hamamelis vernalis - Salix caroliniana Riverscour Alliance Reference: NatureServe Biotics 2019 Description: This alliance includes riverwash communities on gravel or bedrock substrates, primarily dominated by shrubs, and typically found in the Ozark-Ouachita region. These are deciduous or mixed evergreen-deciduous shrublands whose common components (which vary by zone and hydroperiod) include <i>Alnus serrulata, Cephalanthus occidentalis, Cornus obliqua, Hamamelis vernalis, Hamamelis virginiana, Ilex vomitoria, Juniperus virginiana var. virginiana, Phyllanthopsis phyllanthoides, Physocarpus opulifolius, Quercus nigra, Salix caroliniana, Styrax grandifolius</i>, and <i>Vaccinium virgatum</i>. These shrublands occupy various zones in and along rivers and streams in the south-central United States, including gravelly streambanks, upper and lower scour zones, as well as exposed bedrock in the highest portions of these areas. This vegetation is maintained by flash flooding events, and stands are scoured by floods that reach 5 m or more above normal summer pools. This vegetation is primarily known from the Ouachita region of western Arkansas and eastern Oklahoma, and the Ozarks of Arkansas and Missouri, but it may range into adjacent regions to the east.  Accession Code: urn:lsid:vegbank.org:commConcept:39008-{179D0664-732C-4D47-82EB-8F658C37A0B3} Plot-observations of this Community Concept: 0
