CEGL001832 Eleocharis acicularis Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Needle Spikerush Marsh
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a small-statured, small-patch herbaceous wetland community that is common but rarely sampled and is generally overlooked. Stands occur on edges of marshes, on muddy shores, wet basins, exposed pond bottoms or concave areas in meadows or grasslands. This description is based on 14 plots from California, Colorado and Wyoming. Known occurrences are found at elevations between 1460 and 3350 m (4800-11,000 feet). Soils are fine silty clay, loam to sandy loam, and even muck, often over alluvium. Soils are generally saturated throughout the growing season, but the water table may drop to 36 cm by late August. It is typically a low-diversity herbaceous association. The diminutive, rhizomatous, slender perennial graminoid Eleocharis acicularis characterizes sites with its dense tufts. The canopy can be open (10%) or nearly closed (85%). Stands are low in species richness (average of 7 in both California and in Colorado plots). Other graminoid species that may be present include Eleocharis palustris, Pascopyrum smithii, Muhlenbergia filiformis, Carex vesicaria, Bromus arvensis, Echinochloa crus-galli, and Glyceria borealis. Forbs may also be present and include Rorippa sinuata, Marsilea vestita, Ambrosia tomentosa, Trifolium longipes, Sium suave, and Ranunculus flammula.
