Name: Carex lasiocarpa Seasonally Flooded Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Vegetation types within this seasonally flooded, temperate or subpolar grassland alliance are associated with meadows, basins, glacial kettle ponds, and lake margins. Elevations range from 1380 m in Oregon to 2900 m in Utah. Sites are anaerobically favorable to the buildup of deep organic soils. Soils are usually Histosols with thick accumulations of partially decomposed sedges. Soil texture is predominantly loamy. Types occur on poorly drained organic mats. Sites are often flooded into the growing season with water tables remaining within the root zone. Carex lasiocarpa typically is the only dominant graminoid with up to 98% cover. Carex utriculata, Carex aquatilis, and Carex canescens are occasionally present on slightly raised microsites. The forb layer in the Montana stands have up to 40% cover. Species include Symphyotrichum spathulatum (= Aster occidentalis), Argentina anserina (= Potentilla anserina), and Comarum palustre (= Potentilla palustris). Equisetum arvense characterizes the fern layer (0-40% cover) in the Montana sites. Adjacent wetter communities are dominated by either Carex utriculata or Carex aquatilis. Drier communities are dominated by Deschampsia caespitosa or Artemisia cana.  Accession Code: VB.CC.25039.CAREXLASIOCARPA Plot-observations of this Community Concept: 0
