Name: A.1852
Reference: EcoArt 2002
Description: This sparsely vegetated alliance of the Mojave and Colorado deserts is found in active and partially stabilized dune systems between 10 and 1200 m elevation. These dune systems are shaped by abiotic factors and move too rapidly to be stabilized by plants establishing on them. Plant cover is therefore very sparse. Subsurface water is held for long periods of time so shrubs that can survive long enough to get rooted can persist through long droughts. Scattered forbs and grasses in the herbaceous layer characterize this alliance. No one plant is diagnostic, but typically three or more of the following can be found: ~Pleuraphis rigida (= Hilaria rigida), Panicum urvilleanum, Oenothera deltoides, Croton californicus, Abronia villosa, Geraea canescens, Dicoria canescens, Achnatherum hymenoides (= Oryzopsis hymenoides), Cleome sparsifolia$, and ~Rumex hymenosepalus$. Individual emergent shrubs, such as ~Eriogonum deserticola, Larrea tridentata, Atriplex canescens$, and ~Ambrosia dumosa$, may be present. Total plant cover rarely exceeds 10%.
