Name: Carex pellita - (Carex nebrascensis) - Schoenoplectus spp. Saturated Herbaceous Alliance
Reference: Midwestern Ecology Working Group...
Description: This alliance, found in the central Great Plains, occurs where groundwater seeps to the surface. The vegetation of these seepage fens is predominantly hydrophytic graminoids which typically forms dense cover. Common herbaceous species include Carex hystericina, Carex pellita (= Carex lanuginosa), Carex nebrascensis, Eleocharis spp., Eupatorium maculatum, Leersia oryzoides, Scirpus spp., Thelypteris palustris, and Typha latifolia. Shrubs, primarily Salix spp., may occasionally occur. Ferns may be locally common. Species composition is variable between sites and is probably related to factors such as depth and composition of organic soils, water chemistry, and level of disturbance. Vegetation zonation is often conspicuous and related to hydrologic regime. Stands of this alliance are found on mid to lower slopes of hillsides and terraces in canyons and stream valleys. In eastern Nebraska, stands are associated with sandstone outcrops or loess and glacial till slopes. Soils are deep and consist of peat or muck, often mixed with sands. Peat layers range from 0.5-1.5 m deep. Fens are constantly saturated by groundwater. Mounded groundwater discharge zones are common features of these fens. Groundwater pH typically ranges from 6.0-7.5 and is not calcium-rich. The water table is usually near the soil surface.
