What is the origin of peat?
Peat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses, sedges, and shrubs. As it accumulates, the peat holds water. This slowly creates wetter conditions that allow the area of wetland to expand.
When was peat first used?
Peat has been used as a fuel in Ireland for many centuries. Evidence suggests it was used as early as the seventh century. By the 19th century, turf had become one of the main sources of fuel in Ireland, alongside coal.
How and where did peat originate?
Peat is a naturally existing sedimentary material that is both common and unusual; its origins are due to botanical and geological processes, and significant contributions to any peat deposit are attributable to animals, plants, and diverse groups of microbial taxa.
What is peat and why is it important?
It acts as a carbon store, it is a great habitat for wildlife, it has a role in water management, and preserves things well for archaeology. Peat is of great importance to our planet: as a carbon store – peat holds more carbon than the combined forests of Britain, France and Germany.
What does peat mean?
Peat is a rich, dark, dirt-like material that’s made from decomposed organic matter. You can use peat in gardens and potted plants, to help the soil stay moist. Peat is like a naturally occurring compost — it forms in bogs from plants that have broken down.
Does Ireland still burn peat?
Even though turf is inefficient and its fuel value is much lower than coal’s, it’s burned in power plants to create electricity. Still, the Irish government is phasing out peat for electricity and in 2020 the last power plant to exclusively use it went offline. Another plant is to switch to biomass by 2023.
How many countries have peat?
Peatlands are globally important ecosystems and are found in an estimated 180 countries (Parish et al., 2008). Although we know that peatlands are found all over the world, there is no comprehensive mapping of their locations.
How long do peatlands take to form?
It takes approximately a staggering 10 years for 1cm of peat to form! Through analysis of the soil, the types of plants that grew, died and accumulated to form a piece of peat can be discovered. Dead plants in peatlands are different to other ecosystems as they do not fully decompose.
Which country has most peatlands?
Sifting through the statistics on global peatland distribution has also turned up a number of unexpected numbers. For example, would you be surprised to learn that Malaysia has nearly as much peat (c. 26,685 km2) as Norway (c.

Where are the largest peatlands?
In early 2017, scientists announced that they had mapped the largest peatland complex in the tropics – the Cuvette Centrale swamp forest in the Congo Basin – estimated to cover 145,000 km2 and containing more than 30 billion tonnes of carbon (Dargie et al., 2017).
Why are peatlands special?
Peatlands are important source catchments for drinking water and also have a role in the regulation of water flows. They also support species and habitats that depend on often extreme, waterlogged conditions are of international importance for biodiversity conservation.
Why are peatlands drained?
Peatlands have been subject to artificial drainage for centuries. This drainage has been in response to agricultural demand, forestry, horticultural and energy properties of peat and alleviation of flood risk.
