Eleocharis ambigens Fern.
Monocots

Habitat [-]
Only two New York sites with Eleocharis fallax have been described; one was an artificial, weedy wetland adjacent to a wastewater treatment plant, and the other an open wetland adjacent to small pond. More information on the habitat requirements of Creeping Spikerush in New York is needed (New York Natural Heritage Program 2010). Fresh to brackish pond and lakeshores, marshes (FNA 2002). Fresh and brackish swamps along the coast (Gleason and Cronquist 1991).

Associated Ecological Communities [-]
  • Coastal plain pond*
    The aquatic community of the permanently flooded portion of a coastal plain pond with seasonally, and annually fluctuating water levels. These are shallow, groundwater-fed ponds that occur in kettle-holes or shallow depressions in the outwash plains south of the terminal moraines of Long Island, and New England. A series of coastal plain ponds are often hydrologically connected, either by groundwater, or sometimes by surface flow in a small coastal plain stream.

    * probable association but not confirmed
  • Coastal plain pond shore*
    The gently sloping shore of a coastal plain pond with seasonally and annually fluctuating water levels. Plants growing on the pond shore vary with water levels. In dry years when water levels are low there is often a dense growth of annual sedges, grasses, and herbs. Submerged and floating-leaved aquatic plants, such as fragrant waterlily and pondweeds, may become "stranded" on the exposed shore. In wet years when the water level is high only a few emergents and floating-leaved aquatics may be noticeable. The vegetation of this pond shore community can change dramatically from one year to the next depending on fluctuations in groundwater levels.

    * probable association but not confirmed
  • Sewage treatment pond*
    The aquatic community of an artificial pond constructed for sewage treatment (chemical and biological decomposition of sewage) prior to release to a stream or aquifer.
