CEGL008704 Elymus glaucus - Carex pellita Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Blue Wildrye - Woolly Sedge 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. Stands are found at low elevations (1190-1220 m [3900-4000 feet]) at the bottoms of flat mountain valleys (most commonly in Yosemite Valley, locally). Soils are poorly drained to very poorly drained, and textures range from sandy loam to peat from granitic parent material. Litter tends to be high, ranging from 40-99% cover. Water can have 0-50% cover. Disturbance is common and is usually caused by low impact levels from invasion of exotic species and sometimes by low to medium impact levels from road or trail construction. This association forms a continuous herb layer (0.5-1 m tall) dominated by Elymus glaucus, Carex pellita, and Poa pratensis. Often found in this association are Artemisia douglasiana, Agrostis stolonifera, Lotus pinnatus, Carex feta, and Equisetum arvense. Cirsium vulgare, Senecio elegans?, Lotus unifoliolatus, Brodiaea elegans, and Juncus arcticus ssp. littoralis may be found contributing to minor cover. Occasionally, Asclepias fascicularis, Iris missouriensis, Juncus mexicanus, and Rumex acetosella may be common.

Floristics: This herbaceous association forms a continuous herb layer (0.5-1 m tall) dominated by Elymus glaucus, Carex pellita (= Carex lanuginosa), and Poa pratensis. Often found in this association are Artemisia douglasiana, Agrostis stolonifera, Lotus pinnatus, Carex feta, and Equisetum arvense. Cirsium vulgare, Senecio elegans?, Lotus unifoliolatus, Brodiaea elegans, and Juncus arcticus ssp. littoralis (= Juncus balticus) may be found contributing to minor cover. Occasionally, Asclepias fascicularis, Iris missouriensis, Juncus mexicanus, and Rumex acetosella may be common.
Dynamics: Disturbance is common and is usually caused by low impact levels from invasion of exotic species and sometimes by low to medium impact levels from road or trail construction.

Geographic Range: This association is only known from Yosemite National Park. Information about its global characteristics is not available without additional inventory. It is likely to occur in moist meadow edges elsewhere in the Sierra Nevada.
