Name: Carex exsiccata Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: From Christy (2004): This herbaceous vegetation occupies small to large shallow basins on a variety of soil types, mostly seasonally flooded to perennially saturated organic, silt loam, or sand. This association is widely distributed in northwestern Oregon and Washington at elevations ranging from 30 to 1525 m (100-5000 feet). The association is present but uncommon at lower elevations along the coast and in interior valleys of western Oregon, and becomes more common at higher elevations in the Coast and Cascade Range. The composition is diverse with no obvious segregate types. Stands are usually flooded seasonally to a depth of 1-3 feet and may dry out by midsummer with the water table just below the soil surface. <i>Thuja plicata</i> and <i>Pseudotsuga menziesii</i> were recorded from plots but are peripheral or restricted to elevated microsites. Eleven different shrub species are reported, depending on elevation, but most occur in trace amounts except for <i>Spiraea douglasii, Vaccinium uliginosum</i>, and <i>Alnus incana</i>. Stands are usually nearly monotypic reed swamp of <i>Carex exsiccata</i> in standing water or bare mud, but sometimes it occurs with other species in wet lawns. Average cover of <i>Carex exsiccata</i> is 69%, with cover in some plots as much as 100%. More than 90 other species are present in the herb layer, the great diversity due mainly to the variety of elevations at which the association occurs. Most of the other species occur only in trace amounts. Those forming significant patches include <i>Veronica scutellata, Nuphar polysepala (= Nuphar lutea ssp. polysepala), Deschampsia caespitosa, Lysichiton americanus, Torreyochloa pallida var. pauciflora, Juncus patens</i>, and <i>Carex hystericina</i>. Some stands were no doubt grazed by livestock in the past, and elk and deer use may be high locally.  Accession Code: VB.CC.34501.CEGL003312 Plot-observations of this Community Concept: 0
