Name: Picrothamnus desertorum Shrubland Alliance Reference: Western Ecology Working Group of... Description: Little information is available for the Picrothamnus desertorum Shrubland Alliance (A.1128). It is one of the least common salt desert shrub communities. It occurs on alkaline, lacustrine ash deposits of the Owyhee Uplands, along the margins of the large playas, and on alluvial gravel deposits of Pleistocene lake basins. These latter habitats are the most prevalent in Nevada, and thus the alliance may prove to be more common than presently documented. Picrothamnus desertorum (= Artemisia spinescens) is the indicator woody species, with Elymus elymoides the dominant graminoid species. Some valley margins sites with deep ash or alkaline sands support only open understories of Elymus elymoides, Achnatherum hymenoides, and Hesperostipa comata.  Accession Code: VB.CC.23947.PICROTHAMNUSDES Plot-observations of this Community Concept: 0
