Name: Poa secunda - Bromus tectorum Ruderal Grassland
Reference: NatureServe Biotics 2019
Description: This herbaceous vegetation association is dominated by <i>Poa secunda, Bromus tectorum</i>, or a combination of both species. <i>Poa secunda</i> is a native, perennial grass, and <i>Bromus tectorum</i> is an introduced, annual grass. Shrubs may occur sporadically with low densities. <i>Artemisia tridentata ssp. wyomingensis, Chrysothamnus viscidiflorus</i>, and <i>Artemisia tripartita</i> are the most constant native shrubs in this association. In addition to <i>Poa secunda</i>, other native grasses are often present, but no one species occurs with high constancy. Several native perennial and annual forb species may also occur with sparse cover and variable species composition across stands of this type. Non-native forb species are common as well, but species composition is variable. This association occurs on flat to steeply sloping upland sites. Stands occur in swales, gentle slopes and drainage bottoms and valley floors, often with easterly facing aspects. Substrates are deep, well-drained loam, clay loam and silty clay soils. Litter cover is variable but often relatively high. This plant community is often associated with disturbance.
