Name: Californian Acidic Graminoid Fen Alliance
Reference: NatureServe Biotics 2019
Description: This alliance consists of herbaceous acidic fens dominated by <i>Carex aquatilis, Carex lenticularis, Carex utriculata, Darlingtonia californica</i>, and/or <i>Schoenoplectus</i> species. Other characteristic plant species present may include <i>Carex californica, Deschampsia cespitosa, Drosera rotundifolia, Eleocharis quinqueflora</i>, and <i>Calliscirpus criniger</i>. Shrubs and stunted trees may be present, but these with &lt;25% cover. This alliance occurs at low to moderate elevations (0-1400 m) in extreme southern Oregon and throughout northern California, in regions of heavy precipitation (100-250 cm/year) and/or groundwater seepage. These sites remain moist or wet throughout the year and may have substantial <i>Sphagnum</i> accumulation. They are seeps or fens maintained by groundwater discharge. These wetlands have organic soil of peat at least 30 cm thick, with soil/water pH of &lt;5.5. Soils are highly acidic and often composed of ultrabasic parent materials. The acidity and nutrient-poor substrates produce severe nitrogen-deficiency which favors insectivorous plants.
