Name: Eleocharis acicularis Seasonally Flooded Herbaceous Alliance
Reference: Western Ecology Working Group of...
Description: Vegetation types within this seasonally flooded, temperate or subpolar grassland alliance occur in marshes, muddy shores, and other wet places from the lowlands to high elevations in the western United States (specific information on elevation range is not available). Types typically occur in wet basins, exposed pond bottoms, or concave areas in meadows. Sites have water during the first third of the growing season but eventually dry out. Widely fluctuating water tables are typical. Soils are often fine-textured mineral soils. Texture ranges from silt loam to sandy clay loam with thick, dark soil profiles. Soil pH is strongly acidic, 5.4. Eleocharis acicularis, an obligate wetland plant, dominates the graminoid stratum with dense tufts. Percent cover ranges from 25-99%. Muhlenbergia filiformis and Equisetum fluviatile can occur occasionally in the graminoid layer. The forb layer can include Trifolium longipes and Sagittaria cuneata. This plant association's species diversity is normally low. Adjacent drier communities are typically Deschampsia caespitosa or Poa palustris grasslands.
