Any wetland characterized by the accumulation of partially decomposed plant matter.

wetland ecosystem in which organic matter is produced faster than it is decomposed, resulting in the accumulation of partially decomposed vegetative material called peat.

land where plants decomposes only partially and accumulates to form brown to black organic material called peat; two main types bogs and fens.

An area of vegetated matter with extensive peat deposits.

A wetland that accumulates more than 30 cm (40 cm in Canada) of highly organic peat. These originate in two major ways: by the filling in of shallow water bodies and their invasion by semiaquatic peat-forming plants, or by the swamping and waterlogging (paludification) of unsaturated mineral soils in upland situations, with the latter being areally more important than the former. See Gorham (1995).

A generic term of any wetland that accumulates partially decomposed plant matter. Also called Moors in Europe.
