Name: Abronia villosa Sparse Vegetation [Placeholder]
Reference: Western Ecology Working Group of...
Description: This association occurs on the dune systems in southern California, in the Mojave and Sonoran deserts. It is found in active and partially stabilized dune systems throughout these southwestern deserts at elevations between -10 and 1200 m. These dune systems are shaped by abiotic factors and move too rapidly to be stabilized by plant communities. Plant cover is therefore very sparse. Water is held for long periods of time just under the surface by sand, so shrubs that can persist long enough to get rooted can persist through long droughts. This association of desert dune systems is characterized by scattered forbs and grasses in the herbaceous layer. No one species is diagnostic, but typically three or more of the following can be found: Abronia villosa, Pleuraphis rigida (= Hilaria rigida), Oenothera deltoides, Croton californicus, Geraea canescens, Dicoria canescens, Achnatherum hymenoides (= Oryzopsis hymenoides), Cleome sparsifolia and/or Rumex hymenosepalus. Individual emergent shrubs may be present, such as Eriogonum deserticola, Larrea tridentata, Atriplex canescens, and/or Ambrosia dumosa. Total plant cover rarely exceeds 10%.
