Peat in Lewis, Scotland. 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.
All mires are initially fens when the peat starts to form, and may turn into bogs once the height of the peat layer reaches above the surrounding land. 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 ).
The bog continues to form peat, and over time a shallow dome of bog peat develops into a raised bog. The dome is typically a few meters high in the center and is often surrounded by strips of fen or other wetland vegetation at the edges or along streamsides where groundwater can percolate into the wetland.

Peat located on the fringing areas of domes in between domes might form through lateral expansion. [ 10 ] [ 11 ] This peat accumulation often forms a convex shape called a dome, which could rise up to 4 m (13 ft) on coastal peat and up to 18 m (59 ft) on inland peat. [ 1 ]
