Name: Leymus mollis Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This vegetation occurs on shifting sands of outer coastal dunes at sea level. The climate is strongly maritime with many cloudy or foggy days and mild temperatures. Onshore winds typically transport abundant salt spray and sand. Soils are entirely aeolian sands without horizon development or accumulated organic material. In the Pacific Northwest, this alliance is dominated by medium-tall graminoids, which range in cover from dense to very open (down to 10% cover). The sand substrate is usually visible, and litter accumulation from plant debris is insignificant. Leymus mollis ssp. mollis usually dominates the stands, but associated species may be abundant or even codominant; Abronia latifolia, Calystegia soldanella, Ambrosia chamissonis, and Cakile spp. are the most common. Sparsely scattered shrubs and trees may also occur, particularly near the landward edge, including Gaultheria shallon, Arctostaphylos uva-ursi, Arctostaphylos columbiana, Salix hookeriana, Ledum glandulosum, Lonicera involucrata, and Pinus contorta. Contiguous vegetation types are usually sparse Abronia - Cakile strand communities or bare sand at the seaward margin and Gaultheria - Salix - Arctostaphylos inner dune shrub communities at the landward edge. This vegetation may alternate with non-native Ammophila arenaria dunegrass communities along the outer dune front.  Accession Code: VB.CC.22279.LEYMUSMOLLISHER Plot-observations of this Community Concept: 0
