Name: Juncus arcticus ssp. littoralis - Juncus mexicanus Wet Meadow Alliance
Reference: NatureServe Biotics 2019
Description: These wet meadows are dominated by <i>Juncus arcticus ssp. littoralis</i> or <i>Juncus mexicanus</i>. The graminoid layer is dense with up to 98% cover and dominated by <i>Juncus arcticus ssp. littoralis</i>, a creeping, often sod-forming, rhizomatous perennial. Other graminoid cover is minor but can include <i>Carex aquatilis, Carex canescens, Carex pellita, Deschampsia cespitosa, Hordeum jubatum, Leymus cinereus, Sporobolus airoides</i>, and many others. Forb cover is typically minor and may include <i>Achillea millefolium, Iris missouriensis</i>, or <i>Geum macrophyllum</i>, among many others. This alliance covers montane stands of California, the Pacific Northwest, Rocky Mountains, and Great Basin at 1000-3600 m (3300-11,800 feet) elevation and excludes lower elevation and coastal-influenced areas. This alliance is very widespread and can occur in many types of wet meadows. It can occur naturally as a native community, but is more commonly encountered because of heavy prolonged grazing by livestock.
