CEGL003427 Carex amplifolia Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bigleaf Sedge Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is known from the Coast Ranges of Oregon, the west and east sides of the Cascades, the Blue Mountains of northeastern Oregon, southeastern Idaho, and Washington. The association is known from V- and trough-shaped valleys at low to moderate elevations of 744 to 1937 m (2440-6350 feet). Stands develop on floodplains with a constant source of water from adjacent springs and on subirrigated, or spring-fed, saturated toeslopes and terraces (up to 10% or more slope). Water is at or near the surface for most of the growing season, and it often ponds on, or just below, the soil surface. Soils are variable, sometimes having coarse fragments, and may be organic or mineral. Carex amplifolia has moderate to high cover (averaging 40-60%). Glyceria striata, Juncus ensifolius, and Scirpus microcarpus occur frequently, usually with low to moderate cover. Alnus incana is sometimes present with low cover. No single perennial forb has high cover or constancy, although Epilobium spp., Equisetum arvense, and Mimulus guttatus are the most commonly occurring. Moss cover averages over 20%.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Classification of this association is based on at least 17 plots in Oregon, and 1 in Washington (Crowe and Clausnitzer 1997, Crowe et al. 2002). Stands of Carex amplifolia have been observed in Idaho, and quantitative data are available from 1 site (IDCDC 2002). Kovalchik (1987) described a very similar Scirpus microcarpus - (Carex amplifolia) plant association that is dominated by Scirpus microcarpus and/or Carex amplifolia. If any of these stands are dominated or codominated by Carex amplifolia, these stands are likely synonymous with this Carex amplifolia association. Kovalchik''s stands typically occurred on fluvial surfaces rather than in association with springs or seeps. Overall, the high cover and dominance by Carex amplifolia distinguishes this association from similar types.

Floristics: Carex amplifolia has moderate to high cover (averaging 40-60%). Glyceria striata, Juncus ensifolius, and Scirpus microcarpus occur frequently, usually with low to moderate cover. Alnus incana is sometimes present with low cover. No single perennial forb has high cover or constancy, although Epilobium spp., Equisetum arvense, and Mimulus guttatus are the most commonly occurring. Moss cover averages over 20%.

Environmental Description: The association is known from V- and trough-shaped valleys at low to moderate elevations of 744 to 1937 m (2440-6350 feet).

Water is at or near the surface for most of the growing season, and it often ponds on, or just below, the soil surface. Soils are variable, sometimes having coarse fragments, and may be organic or mineral.
Geographic Range: This association is known from localized wetlands in Oregon, Idaho and Washington. It is known from the Coast Ranges of Oregon, the west and east sides of the Cascades, the Blue Mountains of northeastern Oregon, southeast Idaho, and Washington (Crowe and Clausnitzer 1997, IDCDC 2002, Crowe et al. 2002). Very similar, possibly synonymous, stands are described from central Oregon (Kovalchik 1987). Very small, but distinct, stands (less than 0.1 acre) have been observed in west-central Idaho.
