In natural peatlands, the 'annual rate of biomass production is greater than the rate of decomposition', but it takes 'thousands of years for peatlands to develop the deposits of 1.5 to 2.3 m [4.9 to 7.5 ft], which is the average depth of the boreal [northern] peatlands'. Moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. Soils consisting primarily of peat are known as. Peat forms in conditions, where flooding obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition.

This allows humans to reconstruct past environments and study changes in human land use. Peat is harvested as an important source of in certain parts of the world. By volume, there are about 4 trillion cubic metres (5.2 trillion cubic yards) of peat in the world, covering a total of around 2% of the global land area (about 3 million square kilometres or 1.2 million square miles), containing about 8 billion of energy. Over time, the formation of peat is often the first step in the geological formation of other such as, particularly low-grade coal such as. Depending on the agency, peat is not generally regarded as a, due to its extraction rate in industrialized countries far exceeding its slow regrowth rate of 1mm per year, and as it is also reported that peat regrowth takes place only in 30-40% of peatlands.
