Name: North Pacific Maritime Coastal Ruderal Dune Group
Reference: NatureServe Biotics 2019
Description: This group occurs on shifting sands of outer coastal dunes and other sandy areas at sea level from California to Washington and likely British Columbia. Substrates are entirely eolian sands without horizon development or accumulated organic material. These dunes systems are dominated by, and have been physically modified by, the introduction of non-native beachgrasses <i>Ammophila arenaria</i> and <i>Ammophila breviligulata</i> or restoration areas of planted <i>Leymus mollis ssp. mollis</i> (the native dunegrass). In addition, there are areas of introduced low shrubs such as <i>Mesembryanthemum</i> spp. and <i>Carpobrotus</i> spp. Several other non-native species may be dominant, but generally are limited to those that can invade and thrive in the shifting sand and salt-spray environment of the coastal sand dunes and sandsheets. With time the sand dunes become stabilize and vegetative cover increases, at which point other invasive species may appear. Other non-native species may also be present, including <i>Bromus diandrus, Cirsium vulgare, Poa pratensis</i>, and <i>Rumex acetosella</i>.
