A water table near the peat surface gives the opportunity for anaerobic microorganisms to flourish. Methanogens are strictly anaerobic organisms and produce methane from organic matter in anoxic conditions below the water table level, while some of that methane is oxidised by methanotrophs above the water table level.
Peat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses, sedges and shrubs. As it accumulates, the peat holds water. This slowly creates wetter conditions that allow the area of wetland to expand.
First by sucking up water and second through temporary surface-storage. When peat sucks up water, the groundwater level elevates and captures the rainwater, this is then only released by evapotranspiration, as the water does not flow down the rivers into the sea, but stays in the peatland, it too reduces the propability of droughts.

The stem portion consists of two important sections. The pith which is the site of food production and storage, and the cortical layer which serves to absorb water and protect the pith. Mosses have no vascular system to move water and nutrients around the plant. Thus tissues are thin and usually one cell thick to allow them to diffuse easily.
Home to endangered and threatened species, the area buffers storms and is a vital source of drinking water for millions of Floridians. Decades of engineering projects for development and agriculture partitioned and drained water that once flowed freely from the Kissimmee River to Lake Okeechobee to the Florida Bay.
The formation of floating mats is a process of sedimentation in water bodies. In bog ponds, floating mats of peat moss form as water levels fall and nutrients accumulate. In eutrophic waters, the formation of floating mats is caused by underwater peat that floats to the surface and is colonised by plants. The vegetative mats are held together ...
Peat swamp forests are typically surrounded by lowland rain forests on better-drained soils, and by brackish or salt-water mangrove forests near the coast. They are a kind of peatland, which store and accumulate vast amounts of carbon as soil organic matter—much more than forests on mineral soil (i.e. non-peatland) contain.
Peat buildup is possible because water prevents oxygen from quickly decomposing plant matter. Once peat buildup reaches the surface, oxygen reacts with the microorganisms to decay the peat rapidly in a process called subsidence. Initial attempts at developing agriculture near Lake Okeechobee were successful, but the nutrients in the peat ...
