A swamp is a forested wetland. [1] Swamps are considered to be transition zones because both land and water play a role in creating this environment. [2] Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater.
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 .
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]

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 ...
The depth of the water also varies greatly, from a few centimeters to several meters. These physical factors affect the ecology of freshwater swamp forests, either singly or in combination. [5] Rain, rivers, and groundwater are all sources of water for freshwater swamp forests, whereas rain is the only source of water for peat swamp forests. [6]
Of North American freshwater species, an estimated 48.5% of mussels, 22.8% of gastropods, 32.7% of crayfishes, 25.9% of amphibians, and 21.2% of fish are either endangered or threatened. [24] Extinction rates of many species may increase severely into the next century because of invasive species, loss of keystone species, and species which are ...
moss bog) is a peat-forming ecosystem found in several northern climates, most commonly in Arctic and boreal areas. 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]
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 ...
