Peatlands are areas of land with naturally formed layers of peat.
Peat deposits are found in many places around the world, including northern Europe and North America.
Peatland features can include ponds, ridges, and raised bogs.
naturally released from the peat, maintaining an equilibrium.
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".
Indonesia has more tropical peatlands and mangrove forests than any other nation on earth, but Indonesia is losing wetlands by 100,000 hectares (250,000 acres) per year.
