Name: Darlingtonia californica Saturated Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alliance occurs at low to moderate elevations (0-1400 m) of the central Pacific ranges, 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 Sphagnum accumulation. They may be bogs in the true sense, with moisture primarily from rainfall, or more commonly they are seeps or fens maintained by groundwater discharge. 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. This alliance is characterized by an herbaceous canopy of Darlingtonia californica, a carnivorous plant which usually forms clonal populations. A shorter herbaceous layer is usually dominated by forbs and graminoids which tolerate saturated, nutrient-poor soils, including Carex spp., Cypripedium californicum, Rudbeckia californica, and Parnassia palustris. Other carnivorous plants can be common, such as Drosera rotundifolia. There are occasional scattered emergent trees or shrubs, including Rhododendron occidentale, Ledum glandulosum, and Chamaecyparis lawsoniana. Sphagnum spp. may form a thick moss layer on the ground surface. These communities are usually surrounded by Pseudotsuga - Tsuga - Picea forest in coastal areas and Abies - Pinus - Calocedrus-mixed conifer forest in the Sierra Nevada.  Accession Code: VB.CC.25221.DARLINGTONIACAL Plot-observations of this Community Concept: 0
