Name: Distichlis spicata Alkaline Wet Meadow Alliance
Reference: NatureServe Biotics 2019
Description: This alkaline or saline wetland herbaceous alliance covers grasslands of playas and ephemeral streams. Cover may be a sparse or dense herbaceous layer dominated by <i>Distichlis spicata</i>, sometimes occurring in nearly pure stands, or with any of the following as a codominant: <i>Carex filifolia, Hordeum jubatum, Juncus arcticus ssp. littoralis, Pascopyrum smithii, Puccinellia nuttalliana</i>, and/or <i>Sporobolus airoides</i>. Forb cover is generally low and may include Asteraceae spp., <i>Helianthus</i> spp., <i>Salicornia rubra, Suaeda calceoliformis</i>, and <i>Triglochin maritima</i>. Occasionally <i>Suaeda</i> may be the dominant species and <i>Distichlis</i> may be completely absent. This alliance occurs throughout much of the semi-arid and arid western U.S. on saline or alkaline soils in lowland sites such as playas, swales and terraces along washes that are seasonally, temporarily or intermittently flooded. Soils are deep, saline, alkaline and fine-textured. They generally have an impermeable layer and therefore are poorly drained. When the soil is dry, the surface usually has salt accumulations.
