Name: Artemisia arbuscula ssp. arbuscula / Bromus tectorum Ruderal Shrubland
Reference: NatureServe Biotics 2019
Description: <i>Artemisia arbuscula ssp. arbuscula</i> dominates this association and the low-statured stands tend to occur with relatively open canopies. <i>Artemisia tridentata ssp. wyomingensis</i> or <i>Artemisia tridentata ssp. vaseyana</i> often occur and may codominate some stands. The herbaceous layer is generally sparse to moderate in terms of cover and is generally dominated by the introduced annual grass <i>Bromus tectorum</i>. In some stands, <i>Bromus arvensis</i> may replace <i>Bromus tectorum</i> as the most abundant graminoid species, and both annual grass species may occasionally codominate the sparse herbaceous layer. Various native, perennial graminoids may be present, but with very low cover. Forb cover is often variable and sparse. Stands typically occur on poorly drained soils on a variety of landforms; from flats and depressions to slopes and ridges. Soils are usually shallow, rocky clays, often with an impenetrable layer at less than 60 cm depth. Climate is typified by a large proportion of precipitation falling as winter snow. Poor drainage often leads to elevated water tables in the spring, which may control the distribution of the vegetation in this association.
