Name: Eriogonum deserticola Sand Dune Sparse Vegetation
Reference: Western Ecology Working Group of...
Description: This association occurs on active dunes in the extreme southwestern portion of Arizona, southeastern California and likely occurs in adjacent Sonora, Mexico. Sparse stands of dune vegetation included in this type occur in the lower Sonoran Desert below 100 m elevation. Stands occur on active and partially stabilized dunes. Sites are level to steep, include all aspects, and the substrates are deep, shifting dune sands. Total vegetation canopy cover may be less than 10% and is dominated by the dwarf-shrub <i>Eriogonum deserticola</i>. The perennial bunchgrass <i>Pleuraphis rigida (= Hilaria rigida)</i> is codominant in some stands. Species diversity is typically low compared to adjacent vegetation. Other species present include shrubs and dwarf-shrubs such as <i>Ambrosia dumosa, Croton wigginsii, Ephedra trifurca, Larrea tridentata, Parkinsonia microphylla, Psorothamnus emoryi</i>, and the forbs, <i>Brassica tournefortii, Cryptantha</i> sp., <i>Dicoria canescens</i>, and <i>Palafoxia arida</i>.
