Name: Poliomintha incana Shrubland Alliance Reference: Western Ecology Working Group of... Description: This shrubland alliance occurs on sandy sites in north-central and south-central New Mexico. Stands occur in both stabilized deep sand and areas near active dunes. Vegetation included in this alliance is characterized by a sparse woody layer dominated by the xeromorphic evergreen shrub Poliomintha incana with Artemisia filifolia present to codominant. The two different habitats produce stands with different associated species. Stabilized deep sand sites in northern New Mexico have higher shrub diversity with scattered Juniperus monosperma and Pinus edulis trees. Common shrubs and dwarf-shrubs include Gutierrezia sarothrae, Brickellia californica, Ericameria nauseosa var. bigelovii (= Chrysothamnus nauseosus ssp. bigelovii, and the cacti Opuntia phaeacantha and Opuntia polyacantha. The perennial grasses Bouteloua gracilis, Sporobolus cryptandrus and Schizachyrium scoparium dominate the sparse herbaceous layer. The stands described from the dune area have a sparse herbaceous layer that is dominated by perennial graminoids like Sporobolus flexuosus or by annual forbs, such as Chamaesyce parryi, that are seasonally present to abundant in wet years. Weedy annual forbs like Amaranthus spp., Dimorphocarpa wislizeni (= Dithyrea wislizeni), and the exotic Conyza canadensis are common. Diagnostic of this alliance is the relatively sparse shrub layer dominated by Poliomintha incana.  Accession Code: VB.CC.18041.POLIOMINTHAINCA Plot-observations of this Community Concept: 0
