Common (Translated Scientific) Name: Showy Sedge - Arrowleaf Ragwort Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This herbaceous association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This herbaceous vegetation has been described from drainages in the lower alpine zone near treeline (3110 m [10,200 feet] elevation). The stands are narrow (<10 m wide) and occur on the banks of a high-gradient ephemeral stream. Sites are cold, moist and may be shaded by nearby trees. They accumulate deep snowpacks in winter and are temporarily flooded in the spring during snowmelt. The substrate is typically shallow, stony, and derived from alluvium. The soil is saturated near the surface most of the growing season. Soil texture is variable and ranges from deposits of sand and silt to silty clay loam. This temporarily flooded herbaceous association is dominated by Carex spectabilis with traces of emergent Salix orestera. Several forbs and graminoids are present at low cover values. The forb Senecio triangularis is diagnostic. Poa wheeleri attains 2.5% cover, and other graminoids present at trace amounts may include Carex heteroneura, Carex vernacula, Juncus mertensianus, Poa fendleriana ssp. fendleriana, and Trisetum spicatum. Mimulus tilingii is the most common forb. Antennaria media, Penstemon heterodoxus, Phleum alpinum, Potentilla flabellifolia, Stellaria calycantha, and/or Veronica wormskjoldii may be present in trace amounts.

Floristics: This association is only known from the vicinity of Yosemite. Information about its global characteristics is not available without additional inventory. In general, associations in this alliance are lush herbaceous communities with a mixture of forbs and graminoids. Carex spectabilis is the dominant species in terms of cover and constancy. Forbs also have high constancy.
Dynamics: No Data Available
Environmental Description: This association is only known from the vicinity of Yosemite. Information about its global characteristics is not available without additional inventory. In general, communities in this alliance occur on well-drained, moderately steep to steep slopes that are clear of snow by early summer. Soils are composed of varied parent materials but are usually young and poorly developed. This alliance often forms part of a subalpine parkland mosaic just below the upper treeline (NatureServe Ecology - Western U.S. unpubl. data 2001).
Geographic Range: This herbaceous association is currently only known from Yosemite National Park in California. Additional range information will be added as it becomes available.
