8. Peatlands
Formation
- Glaciers melt (began forming 7,000 years ago), vegetation grows around low lying areas
- Plant remains slowly compressed over hundreds of years to fill an entire lake
- Plants such as Sphagnum mosses colonise at the surface, transforming into a bog when they died.
- Saturated soil helps to form raised bogs as peat naturally formed a dome over the land below.
- waterlogged environment creates oxygen-deficient anaerobic conditions. limits decomposition of organic matter
-
-
Globally, 2/3 peatlands located in Indonesia. Stores double the amount of carbon stored in all forests
-
management
Aims to decrease carbon emissions by 25%, with an extra 15% if international aid is given
Dartmoor Mires Project

-
Dig ditches to drain land, oxidising the peat which turns to CO2 and disappears
