Name: Carex spectabilis - Sibbaldia procumbens Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: 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 alpine herbaceous vegetation grows at about 3200 m (10,500 feet) of elevation on moderate to steep slopes near seeps. Aspects are generally south, and substrates are seasonally saturated silt loams derived from granitic or metamorphic parent materials. This is a well-drained community that occurs on stony and/or bouldery slopes often in small patches at the base of outcrops. This alpine grassland is heavily dominated by <i>Carex spectabilis</i>. No other graminoid or forb species achieves more than 1% cover, though 55 species have been recorded on plots of this type. Graminoids with high constancy include <i>Poa secunda, Calamagrostis breweri, Trisetum spicatum</i>, and various <i>Poa, Juncus</i>, and <i>Elymus</i> species. The forb <i>Sibbaldia procumbens</i> is diagnostic but attains only 0.3% cover and 70% constancy. Similar cover and constancy values are attained by the forbs <i>Penstemon heterodoxus, Polygonum bistortoides, Rumex paucifolius</i>, and <i>Potentilla</i> spp.
