Salix eastwoodiae / Deschampsia cespitosa Wet Shrubland
Translated Name: Mountain Willow / Tufted Hairgrass Wet Shrubland
Unique Identifier: CEGL003128
Classification Approach: International Vegetation Classification (IVC)
Summary: This willow association is found in the upper montane, subalpine, and alpine locations, predominantly occurring throughout the central and southern Sierra Nevada. Stands are generally moderate to large in size for riparian communities, often covering several acres. Stands of this shrubland are found adjacent to or near streambanks in mesic to wet meadows at mid to high elevations (2110-3350 m [6920-11,000 feet]). Slopes are gentle to moderate (5-20%). They often appear in basins or as stringer meadows with streams present. These sites are at the bottom of broad to very broad valleys with moderate upland slopes and variable valley bottom gradients. This association is often found near first-order streams within the upper portions of mountain drainages. Slopes are usually convex in shape. Stands are formed on volcanic flows and glaciated granitic batholiths. The stands are seasonally to permanently saturated. Water typically is received by subsurface and overland flows from upstream slopes or upslope on a seasonal basis. Along streams, these stands can be seasonally flooded; however, the association does not appear to be significantly influenced by streamside disturbance. Stands form a two-story structure with a moderately open to intermittent low to moderately tall shrub layer dominated by Salix eastwoodiae. The understory herbaceous layer can be well-developed with openings in the shrub layer occur. A variety of species found in the herbaceous layer includes Oreostemma alpigenum, Mimulus primuloides, Polygonum bistortoides, Allium validum, Perideridia parishii, Deschampsia cespitosa, Carex scopulorum, Trisetum spicatum, Carex subnigricans, Phleum alpinum, Calamagrostis breweri, and Calamagrostis canadensis. Moss is commonly found in this association.
