Name: Atriplex gardneri / Monolepis nuttalliana Dwarf-shrubland Reference: Western Ecology Working Group of... Description: This open dwarf-shrubland occurs on low ridges and toeslopes in badlands in the Big Horn Basin of Montana and Wyoming. Elevation ranges from 1500-1600 m. The association is restricted to arid climatic regimes and sites with deep, heavy clay soil derived from shale, clay or bentonite deposits. The soil has extremely low infiltration, and although gently sloping, it is typically eroded. Gravel and salt deposits are often present on the surface. Stands typically have a relatively sparse dwarf-shrub canopy (35% mean cover) that is dominated by Atriplex gardneri. Scattered Sarcobatus vermiculatus and Suaeda moquinii (= Suaeda nigra) may also be present. Herbaceous cover is dominated by the annual forb Monolepis nuttalliana with 34% mean cover. Other species may include sparse cover of the grasses Hordeum jubatum, Achnatherum hymenoides (= Oryzopsis hymenoides), scattered forbs such as Platyschkuhria integrifolia, Allium textile, Camissonia scapoidea, Musineon divaricatum, and the cactus Opuntia polyacantha. There are nine other dwarf-shrublands and two shrublands with Atriplex gardneri dominant or codominant in the canopy, but none have herbaceous layers dominated by Monolepis nuttalliana.  Accession Code: VB.CC.20988.ATRIPLEXGARDNER Plot-observations of this Community Concept: 0
