Name: Trichophorum caespitosum Semipermanently Flooded Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Trichophorum caespitosum - Carex livida Herbaceous Vegetation (CEGL001842) defines this alliance. It is found in marshes and bogs in central Idaho. It occurs in bogs located in wide valley bottoms that are supported by many rivulets. This association is found on gentle slopes (1-7%). It occurs perched above the valley center along the edges or on toeslopes. The elevation ranges from 2070-2190 m. Soils are variable but tend to be comprised of organic materials. The wettest communities are organic mats floating on water or muck. Slightly drier sites have organic mats overlying saturated mineral layers, with large rocks protruding as shrubby hummocks. Still drier sites have soils with proportionately greater mineral composition. Mineral parent materials are strictly granitic, derived from Idaho Batholith and Sawtooth Batholith formations. The plant association within this alliance is classified as a semipermanently flooded temperate or subpolar grassland. Trichophorum caespitosum-dominated the graminoid layer with at least 5% cover. Carex livida is generally present, with up to 75% coverage in some stands. Other herbaceous species commonly present in the Idaho study are Gentiana calycosa, Packera buekii (= Senecio cymbalarioides), Spiranthes romanzoffiana, Swertia perennis, and Carex muricata. Moss, including Sphagnum spp. may be prevalent on the ground surface. Small hummocks usually support stunted Vaccinium uliginosum (= Vaccinium occidentale) and Lonicera caerulea shrubs.  Accession Code: VB.CC.27783.TRICHOPHORUMCAE Plot-observations of this Community Concept: 0
