Name: Carex aquatilis var. dives - Comarum palustre Fen
Reference: NatureServe Biotics 2019
Description: This herbaceous association occurs on flooded peat encroaching as floating mats on shores of lakes, and in low-gradient drainages where water is ponded or moving very slowly by sheet flow or percolation through the peat. It ranges from Oregon to British Columbia. The surface usually has several inches of standing water and the vegetation is typically very wet or flooded. It may occur on floating mats of peat on what was previously open water, and is a transitional vegetation type between aquatic bed vegetation and open mire or shrub swamp. Trees are rarely present and may include <i>Pinus contorta</i> or sapling <i>Picea sitchensis</i>. Shrubs are present in about half the plots at very low cover and may include <i>Ledum glandulosum, Vaccinium uliginosum, Spiraea douglasii, Lonicera involucrata</i>, or <i>Salix hookeriana</i>. The herb layer is diverse, dominated by <i>Carex aquatilis var. dives</i> and <i>Comarum palustre</i>, with lesser amounts of <i>Nuphar polysepala, Athyrium filix-femina, Hypericum anagalloides, Carex exsiccata, Equisetum fluviatile, Oenanthe sarmentosa</i>, and <i>Lycopus uniflorus</i>. <i>Carex obnupta</i> occurred only in trace amounts in the plots sampled, but may be more abundant in some sites. <i>Sphagnum</i> and other mosses are often present but not dominant.
