Name: Achnatherum nelsonii - Lupinus argenteus Grassland
Reference: NatureServe Biotics 2019
Description: These northern lower montane and valley grasslands are typified by cool-season perennial bunchgrasses and forbs (&gt;25% cover), sometimes with a sparse (&lt;10% cover) shrub layer. <i>Achnatherum nelsonii</i> is the dominant graminoid species in this association. <i>Elymus trachycaulus</i> may also be common. <i>Lupinus argenteus</i> is characteristic of the plant community and is usually the most abundant forb species. It may be a codominant at a local scale. Additional forb species are variable in both cover and species composition. This plant community can occur under a broad range of environmental conditions, on flat to somewhat steep slopes from the basin floor to high slopes at various aspects. It is often found within a matrix of <i>Artemisia tridentata</i>-dominated shrublands. Soil texture ranges from moderately well-drained to rapidly drained silt loam or clay. These are generally moderately to well-developed, medium- to coarse-textured soils. Litter and small rock often dominate the non-vegetated ground surface.
