Reference: EcoArt 2002
Description: This herbaceous alliance has been reported from temporarily flooded, subalpine meadows in the Sierra Nevada near Lake Tahoe at elevations from 2330-2850 m. Stands occur on nearly flat to gently sloping sites on all aspects, and sites include stream terraces and floodplains. Soils are generally deep, well-drained and slightly acid. These stands are often subirrigated and have a shallow water table, usually >1 m, but occasionally up to 0.5 m below the surface. This alliance typically occurs as small patches within forested landscapes. Total vegetation cover ranges from 80-100%. Stands have a tall herbaceous layer dominated by the rhizomatous, perennial forb ~Veratrum californicum$. Other characteristic perennial forbs include ~Oreostemma alpigenum var. andersonii (= Aster alpigenus ssp. andersonii), Epilobium halleanum, Gentiana newberryi, Erigeron peregrinus$, and ~Mimulus primuloides$. Graminoids, such as ~Agrostis variabilis, Carex abrupta, Deschampsia caespitosa, Juncus nevadensis$, and ~Phleum alpinum$, are commonly present.
