Name: Eragrostis hypnoides - Gnaphalium palustre Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: From Christy (2004): This herbaceous vegetation occurs from California to British Columbia and eastward at 12 to 152 m (40-500 feet) elevation. Habitat is low-elevation beds of dried shallow seasonal pools and lakes. Soils are seasonally flooded to saturated silt loam. Trees are peripheral and not included in plots, but the setting is usually adjacent to bottomland forest of <i>Fraxinus latifolia</i> and <i>Populus balsamifera ssp. trichocarpa</i>. <i>Salix lucida ssp. lasiandra</i> is present in half the sampled plots, and <i>Salix fluviatilis</i> is also often present, but neither occurs in large amounts. The herb layer contains about 20 annual and perennial species adapted to early-season inundation and subsequent exposure as lakes and ponds dry up. Most exotic species are excluded by inundation extending into the growing season. <i>Eragrostis hypnoides</i> is the primary species with an average cover of 37% and cover ranging up to 85%, while <i>Gnaphalium palustre</i> has somewhat lower constancy but similar cover when present. <i>Lindernia dubia</i> forms patches in some stands. The remaining species occur only in trace amounts. <i>Eragrostis hypnoides</i> forms a loose and patchy sod with <i>Gnaphalium</i>, and considerable bare ground may be present. These sites appear to be drier than those occupied by the mudflat vegetation of <i>Lilaeopsis occidentalis</i> or <i>Azolla</i> associations, the mud often cracking deeply and the top layer losing most of its moisture.  Accession Code: VB.CC.34170.CEGL003327 Plot-observations of this Community Concept: 0
