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 lagg is an area of wetland, especially at the edge of raised bogs, in which water collects. [2] It is often markedly different from the terrain either side and may consist of a morass of shrubs and murky water.
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]
Wetlands within this category include inland marshes and swamps as well as bogs, fens, pocosins, tundra and floodplains. According to the Cowardin classification system, palustrine wetlands can also be considered the area on the side of a river or a lake, as long as they are covered by vegetation such as trees, shrubs, and emergent plants.

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]
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.
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 ...
