A quagmire is a floating (quaking) mire, bog, or any peatland being in a stage of hydrosere or hydrarch (hydroseral) succession, resulting in pond-filling yields underfoot (floating mats). Ombrotrophic types of quagmire may be called quaking bog (quivering bog). Minerotrophic types can be named with the term quagfen.
Bubbles of methane, created by methanogens, that are present in the marsh, more commonly known as marsh gas. Marsh gas, also known as swamp gas or bog gas, is a mixture primarily of methane and smaller amounts of hydrogen sulfide, carbon dioxide, and trace phosphine that is produced naturally within some geographical marshes, swamps, and bogs.
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]
Luhasoo bog in Estonia.The mire has tussocks of heather, and is being colonised by pine trees.. This is a list of bogs, wetland mires that accumulate peat from dead plant material, usually sphagnum moss. [1]
The result is a large number of wetland classification systems that each define wetlands and wetland types in their own way. [1] However, many classification systems include four broad categories that most wetlands fall into: marsh, swamp, bog, and fen. [1]
Forested swamp in Osceola National Forest. Palustrine wetlands include any inland wetland that contains ocean-derived salts in concentrations of less than 0.5 parts per thousand, and is non-tidal. [1] The word palustrine comes from the Latin word palus or marsh. [2]
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]
Bog-wood represents the early stages in the fossilisation of wood, with further stages ultimately forming lignite and coal over a period of many millions of years. 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 .
