Name: Carex simulata Saturated Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Vegetation types within this saturated, temperate or subpolar grassland alliance occur in wet meadows from the foothills to moderate elevations in the mountains. Elevations range from 1350 m in eastern Oregon to 2700 m in Wyoming. Stands occur in wet basins on gentle slopes below seeps and on flat alluvial terraces adjacent to streams. Surface topography is usually smooth to slightly undulating. Soils are typically Histosols with organic matter accumulations 30-120 cm thick, but may be poorly drained, fine-textured mineral soils as well. Redox depletions or reduced matrices are common throughout the profile. Water tables remain at or near the soil surface during the growing season. Soils are slightly acidic to neutral (pH 6.0-7.0). The soils often quake when walked on due to cold, mucky, groundwater flowing just below the surface. Carex simulata dominates the graminoid stratum with 30-80% cover. Other graminoid species include Carex aquatilis, Carex utriculata, Deschampsia caespitosa, and Juncus balticus. Forb cover is sparse and includes Pedicularis groenlandica and Triglochin maritima. Shrub species are uncommon, typically forming less than 5% cover. Shrub species include Betula nana (= Betula glandulosa), Salix wolfii, and Salix planifolia. The moss layer may be dense with up to 90% cover. Adjacent vegetation includes Schoenoplectus acutus (= Scirpus acutus) on wetter sites and Carex utriculata and Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda) on drier sites.  Accession Code: VB.CC.18237.CAREXSIMULATASA Plot-observations of this Community Concept: 0
