CEGL005662 Carex atherodes Interior West Wet Meadow
Type Concept Sentence: Western U.S. wet meadows dominated by Carex atherodes.
Common (Translated Scientific) Name: Wheat Sedge Interior West Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This sedge wet meadow occurs in a disjunct population in Idaho, but may have more occurrences in the Intermountain West. Stands occur on lowland sites that have standing water for several weeks each year. These sites are typically in depressions or basins but can be along streams and rivers. The water may be fresh or moderately saline. Soils can be mineral but mucks often form through the buildup of organic material. Vegetation cover is usually high but can vary in wet or dry years. Dominant species are herbaceous and typically between 0.5 and 1 m tall. Forb diversity is moderate to high. Carex atherodes may form essentially monotypic stands or just be the dominant species. Common associated species include Symphyotrichum lanceolatum and Eleocharis palustris.
Diagnostic Characteristics: Wet meadows dominated by Carex atherodes.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This type is distinct from ~Carex atherodes Wet Meadow (CEGL002220)$$, as it is found in southeastern Idaho (at Camas National Wildlife Refuge) in a wetland with Eleocharis palustris. So a new association seem warranted.

Physiognomy and Structure: Low perennial graminoid vegetation with heights of 0.5 to 1 m.
Floristics: Vegetation cover is usually high but can vary in wet or dry years. Dominant species are herbaceous and typically between 0.5 and 1 m tall. Carex atherodes can form almost monotypic stands or it may be dominant. Common associated species are Symphyotrichum lanceolatum (= Aster lanceolatus), Eleocharis palustris, Mentha arvensis, and Polygonum amphibium.
