Peatland is a terrestrial wetland ecosystem in which the production of organic matter exceeds its decomposition and a net accumulation of peat results. Peatlands occur in every climatic zone and continent. The total area globally is around 4 million km2 making them 70% of natural freshwater wetland or 3% of the Earth’s land surface. Peatlands include landscapes that are still actively accumulating peat (mires), others that are no longer accumulating and do not support the principal peat forming plants (e.g. Sphagnum spp.), and peatland used for economic uses such as agriculture, forestry and excavation for energy generation, horticulture and a few other…

Peatlands are terrestrial wetland ecosystems in which waterlogged conditions prevent plant material from fully decomposing. Consequently, the production of organic matter exceeds its decomposition, which results in a net accumulation of peat . In cool climates, peatland vegetation is mostly made up of Sphagnum mosses, sedges and shrubs and are the primary builder of peat, whereas in warmer climates graminoids and woody vegetation provide most of the organic matter. Peatlands occur in every climatic zone and continent and cover 4.23 million km 2 , which corresponds to 2.84% of the Earth’s terre
