The two main types of swamp are "true" or swamp forests and "transitional" or shrub swamps. In the boreal regions of Canada, the word swamp is colloquially used for what is more formally termed a bog, fen, or muskeg. Some of the world's largest swamps are found along major rivers such as the Amazon, the Mississippi, and the Congo. [6]
A bog is a mire that, due to its raised location relative to the surrounding landscape, obtains all its water solely from precipitation (ombrotrophic). [7] A fen is located on a slope, flat, or in a depression and gets most of its water from the surrounding mineral soil or from groundwater ( minerotrophic ).
Bog-wood may come from any tree species naturally growing near or in bogs, including oak (Quercus – "bog oak"), pine , yew (Taxus), swamp cypress and kauri . Bog-wood is often removed from fields etc. and placed in clearance cairns. It is a rare form of timber that is "comparable to some of the world's most expensive tropical hardwoods".
A quaking bog, schwingmoor, or swingmoor is a form of floating bog occurring in wetter parts of valley bogs and raised bogs and sometimes around the edges of acidic lakes. The bog vegetation, mostly sphagnum moss anchored by sedges (such as Carex lasiocarpa ), forms a floating mat approximately half a meter thick on the surface of water or ...
There are four main kinds of wetlands – marsh, swamp, bog, and fen (bogs and fens being types of peatlands or mires). Some experts also recognize wet meadows and aquatic ecosystems as additional wetland types. [1] Sub-types include mangrove forests, carrs, pocosins, floodplains, [1] peatlands, vernal pools, sinks, and many others. [22]

Muskeg is approximately synonymous with bog or peatland, and is a standard term in Canada and Alaska. The term became common in these areas because it is of Cree origin; maskek ( ᒪᐢᑫᐠ ) meaning "low-lying marsh".
[1] [2] It is one of the main types of wetland along with marshes, swamps, and bogs. Bogs and fens, both peat-forming ecosystems, are also known as mires. [2] The unique water chemistry of fens is a result of the ground or surface water input. Typically, this input results in higher mineral concentrations and a more basic pH than found in
