Wetlands: reservoirs of carbon
When you think of a wetland you do not often think of tall, dense forests. Neverthless wetlands - areas that maintain a wet soil surface over a certain period of time, ranging from permanently inundated with water to periodicially drained - are often forested and they are also extremely important for climate change mitigation and adaptation because of their role in carbon sequestration.
Wetlands store an impressive amount of carbon in biomass above and below ground, in woody debris and litter and deep in their soils in particular. ‘Histosols’ are the peaty soils that often form in wetlands and, because organic matter, such as plant and animal remains, decomposes slowly where water is present, they are extremely rich in organic material and important reservoirs of carbon.
A new interactive map launched last month that shows the estimated distribution and carbon stocks of wetlands around the world. Registered users can verify and contribute to the map based on their own research and on-the-ground knowledge.
