Fens

Fens are saturated wetlands that are fed by mineral rich (minerotrophic) groundwater. They are primarily dominated by sedges but also usually are also rich in herbaceous species and grasses. Shrubs and tree saplings are common as well. Sphagnum moss, also known as peat moss, is generally absent from fens. Fen soils are rich in organic matter and are often comprised of muck. Some definitions for fens stipulate that fen soils must be a certain depth. Historically, most of Tennessee's fen communities have been categorized as bogs and seeps.
