Peat is an accumulation of partially decayed vegetation or organic matter . It is unique to natural areas called peatlands , bogs , mires , moors , or muskegs . Sphagnum moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. The biological features of sphagnum mosses act to create a habitat aiding peat formation, a phenomenon termed 'habitat manipulation'. Soils consisting primarily of peat are known as histosols . Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition. Peat properties such as organic matter content and saturated hydraulic conductivity can exhibit high spatial heterogeneity .

The origin of this name is unclear, however an apocryphal story links the name to a livestock thief from the early colonial era, who allegedly used the peak as a grazing area for stolen sheep and cattle. The peak was variously called Mount Roskill or Mount Kennedy (after landowner Alexander Kennedy). The name Mount Roskill for the peak and
216-506: A form of erosion that occur at the sides of gullies that cut into the peat; they sometimes also occur in isolation. Hags may result when flowing water cuts downwards into the peat and when fire or overgrazing exposes the peat surface. Once the peat is exposed in these ways, it is prone to further erosion by wind, water and livestock. The result is overhanging vegetation and peat. Hags are too steep and unstable for vegetation to establish itself, so they continue to erode unless restorative action

360-496: A result of peat drainage, the organic carbon—which built over thousands of years and is normally underwater—is suddenly exposed to the air. It decomposes and turns into carbon dioxide (CO 2 ), which is released into the atmosphere. The global CO 2 emissions from drained peatlands have increased from 1,058 Mton in 1990 to 1,298 Mton in 2008 (a 20% increase). This increase has particularly taken place in developing countries, of which Indonesia , Malaysia and Papua New Guinea are

Under 2 °C global warming , 0.7 million km of peatland permafrost could thaw, and with warming of +1.5 to 6 °C a cumulative 0.7 to 3 PgC of methane could be released as a result of permafrost peatland thaw by 2100. The forcing from these potential emissions would be approximately equivalent to 1% of projected anthropogenic emissions. One characteristic of peat
720-539: A tenth of the total permafrost area, and also a tenth (185 ± 66 Gt) of all permafrost carbon, equivalent to around half of the carbon stored in the atmosphere. Dry peat is a good insulator (with a thermal conductivity of around 0.25 Wm K ) and therefore plays an important role in protecting permafrost from thaw. The insulating effect of dry peat also makes it integral to unique permafrost landforms such as palsas and permafrost peat plateaus. Peatland permafrost thaw tends to result in an increase in methane emissions and
792-487: Is also reported that peat regrowth takes place only in 30–40% of peatlands. Centuries of burning and draining of peat by humans has released a significant amount of CO 2 into the atmosphere, and much peatland restoration is needed to help limit climate change . 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,

Also, agricultural and forestry-drained peat bogs actively release more CO 2 annually than is released in peat energy production in Finland. The average regrowth rate of a single peat bog, however, is indeed slow, from 1,000 up to 5,000 years. Furthermore, it
1008-547: Is cut by hand and left to dry in the sun. In many countries, including Ireland and Scotland , peat was traditionally stacked to dry in rural areas and used for cooking and domestic heating. This tradition can be traced back to the Roman period. For industrial uses, companies may use pressure to extract water from the peat, which is soft and easily compressed. In Sweden, farmers use dried peat to absorb excrement from cattle that are wintered indoors. The most essential property of peat

These fires may be responsible for the acceleration in the increase in carbon dioxide levels since 1998. More than 100 peat fires in Kalimantan and East Sumatra have continued to burn since 1997; each year, these peat fires ignite new forest fires above

In a widely cited article, Joosten and Clarke (2002) described peatlands or mires (which they say are the same) as the most widespread of all wetland types in the world, representing 50 to 70% of global wetlands. They cover over 4 million square kilometres [1.5 million square miles] or 3% of

Peat can store nutrients although it is not fertile itself—it is polyelectrolytic with a high ion-exchange capacity due to its oxidized lignin. Peat is discouraged as a soil amendment by the Royal Botanic Gardens, Kew , England, since 2003. While bark or coir -based peat-free potting soil mixes are on

In addition to being soft and therefore suitable for demersal (bottom-dwelling) species such as Corydoras catfish, peat is reported to have many other beneficial functions in freshwater aquaria. It softens water by acting as an ion exchanger ; it also contains substances that are beneficial for plants and fishes' reproductive health. Peat can prevent algae growth and kill microorganisms. Peat often stains

Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon , which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. Peat is not a renewable source of energy , due to its extraction rate in industrialized countries far exceeding its slow regrowth rate of 1 mm (0.04 in) per year, and as it

A catalog of the peat research collection at the University of Minnesota Duluth provides references to research on worldwide peat and peatlands. About 7% of all peatlands have been exploited for agriculture and forestry . Under certain conditions, peat will turn into lignite coal over geologic periods of time.

In Quaternary Palaeoecology , first published in 1980, Birks and Birks described how paleoecological studies "of peat can be used to reveal what plant communities were present (locally and regionally), what period each community occupied, how environmental conditions changed, and how the environment affected the ecosystem in that time and place." Scientists continue to compare modern mercury (Hg) accumulation rates in bogs with historical natural archives records in peat bogs and lake sediments to estimate
