A general term for a mire or peat-forming ecosystem with little or no sphagnum and with a source of water and minerals beyond its limits.
Less acid than bogs, or even alkaline, and mineral rich.
They generally support varied vegetation of grasses, sedges, or reeds. Fens with a scrub or woodland vegetation are carrs.
Fens. Ya gotta lovem. When it comes time to think about mires, fens always come to mind. My mind anyway.
