Includes bog, marsh, and fen. Fens typically have groundwater sustaining them as wetlands, with vegetation, often (but not exclusively) growing over peat, where the water-table is at, or just below, the surface. Water is derived from both rainfall and drainage of surrounding land. Some fens may have Sphagnum moss, but typically the vegetation is dominated by tall reeds, wetland herbs, sedges, and rushes. Bogs have vegetation growing on wet peat; the water source is direct rainfall, or in some cases, over-land flow during heavy rain events. Sphagnum moss is always present, often with bog cotton (Eriophorum). In locally drier areas heather (Calluna, Erica) may also be present, but never dominant
