Ammophila arenaria Coastal Dunegrass Ruderal Grassland Alliance | NatureServe Biotics 2019

Name: Ammophila arenaria Coastal Dunegrass Ruderal Grassland Alliance Reference: NatureServe Biotics 2019 Description: This alliance occurs on shifting sands of outer coastal dunes and other sandy areas at sea level from California to Washington and likely British Columbia. These dune systems have been modified by the introduction of non-native beachgrasses <i>Ammophila arenaria</i> and <i>Ammophila breviligulata</i> or are restoration areas of planted <i>Leymus mollis ssp. mollis</i> (native dunegrass). Additional non-native species such as <i>Holcus lanatus</i> can be codominant with the dunegrass. Other non-native species may also be present, including <i>Bromus diandrus, Cirsium vulgare, Poa pratensis</i>, and <i>Rumex acetosella</i>. Native herbaceous species that may be present but with low abundance include <i>Abronia latifolia, Cakile</i> spp., <i>Galium aparine, Lathyrus littoralis, Poa macrantha</i>, and <i>Pteridium aquilinum</i>. Sparsely scattered shrubs and trees may also occur, particularly near the landward edge, including <i>Arctostaphylos uva-ursi, Arctostaphylos columbiana, Gaultheria shallon, Ledum glandulosum, Lonicera involucrata, Pinus contorta, Rosa nutkana, Rubus ursinus</i>, and <i>Salix hookeriana</i>. Colonization of active sand dunes by introduced species or by restoration planting of native dunegrass has resulted in an increase in the area of stabilized dunes, in some cases more than the historic extent. Substrates are entirely eolian sands without horizon development or accumulated organic material.  Accession Code: urn:lsid:vegbank.org:commConcept:38313-{0AF49442-DB6D-414E-B21E-0FCDF8C184CC} Plot-observations of this Community Concept: 0
