Name: Juncus arcticus ssp. littoralis - (Juncus mexicanus) Wet Meadow
Reference: NatureServe Biotics 2019
Description: This herbaceous association is known from Yosemite National Park, Death Valley National Park and the Channel Islands in California. The following description is based on occurrences at Yosemite. Additional information will be added as it becomes available. Stands of this association have been found from 1280-2895 m (4200-9500 feet) elevation in seasonally flooded valley bottoms and meadows. Slopes are flat to very gentle, and stands can occur on all aspects. Soils are moderately to poorly drained loams, loamy sand, or clay loams. This seasonally flooded perennial grassland is dominated by <i>Juncus arcticus ssp. littoralis</i>, with <i>Juncus orthophyllus</i> and <i>Juncus mexicanus</i> important species at lower cover. <i>Poa pratensis</i> is also usually present. Forbs are sparse but fairly diverse. <i>Achillea millefolium, Iris missouriensis</i>, and/or <i>Taraxacum officinale</i> (exotic) have the highest frequency, though <i>Mimulus primuloides</i> may be abundant in some stands. Total vegetative cover for this association often exceeds 80%, and the canopy is usually less than 0.5 m in height.
