Name: A.1687
Reference: EcoArt 2002
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.
