Peat, sometimes known as turf, is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers 3.7 million square kilometres (1.4 million square miles) and is the most efficient carbon sink on the planet, because peatland plants capture CO2 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", which store around 415 gigatonnes (457 billion short tons; 408 billion long tons) of carbon (about 46 times 2019 global CO2 emissions). Globally, it even stores up to 550 gigatonnes (610 billion short tons; 540 billion long tons) of carbon, representing 42% of all soil carbon and exceeds the carbon stored in all other vegetation types, including the world's forests. Across the world, peat covers just 3% of the land’s surface, but stores one-third of the Earth’s soil carbon. 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
A bog or bogland is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A baygall is another type of bog found in the forest of the Gulf Coast states in the United States. They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink.
The Magellanic subpolar forests are a terrestrial ecoregion of southernmost South America, covering parts of southern Chile and Argentina, and are part of the Neotropical realm. It is a temperate broadleaf and mixed forests ecoregion, and contains the world's southernmost forests.
Sphagnum is a genus of approximately 380 accepted species of mosses, commonly known as "peat moss", though they are different as peat moss has a more acidic pH level. Accumulations of Sphagnum can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species. The empty cells help retain water in drier conditions.
Burns Bog is an ombrotrophic peat bog located in Delta, British Columbia, Canada. It is the largest raised peat bog and the largest undeveloped urban land mass on the West Coast of the Americas. Burns Bog was originally 4,000–4,900 hectares before development. Currently, only 3,500 hectares remain of the bog.
Fenn's, Whixall and Bettisfield Mosses National Nature Reserve is a national nature reserve (NNR) which straddles the border between England and Wales, near Whixall and Ellesmere in Shropshire, England and Bettisfield in Wrexham County Borough, Wales. It comprises three peat bogs, Bettisfield Moss, Fenn's Moss and Whixall Moss. With Wem Moss and Cadney Moss, they are collectively a Site of Special Scientific Interest called The Fenn's, Whixall, Bettisfield, Wem & Cadney Moss Complex and form Britain's third-largest lowland raised bog, covering 2,388 acres (966 ha). The reserve is part of the Midland Meres and Mosses, an Important Plant Area which was declared a Wetland of International Importance under the Ramsar Convention in 1997. It is also a European Special Area of Conservation.
Ballynahone Bog is a raised bog, situated in County Londonderry, Northern Ireland, about 3 km south of Maghera, on low-lying ground immediately north of the Moyola River about 14 km from its mouth at Lough Neagh. It is one of the largest lowland raised bogs in Northern Ireland.
Navarino Island is a Chilean island located between Isla Grande de Tierra del Fuego, to the north, and Cape Horn, to the south. The island forms part of the Commune of Cabo de Hornos, the southernmost commune in Chile and in the world, belonging to Antártica Chilena Province in the XII Region of Magallanes and Chilean Antarctica. Its population is concentrated primarily in the communal capital, Puerto Williams, and in small settlements like Puerto Navarino, Río Guanaco and Puerto Toro. The highest point of the island is Pico Navarino at 1,195 m (3,921 ft). The island is a popular destination for fly-fishers.
Cors Caron is a raised bog in Ceredigion, Wales. Cors is the Welsh word for "bog": the site is also known as Tregaron Bog, being near the small town of Tregaron. Cors Caron covers an area of approximately 349 hectares. Cors Caron represents the most intact surviving example of a raised bog landscape in the United Kingdom. About 44 different species groups inhabit the area including various land and aquatic plants, fish, insects, crustaceans, lichen, fungi, terrestrial mammals and birds.
Aulacomnium palustre, the bog groove-moss or ribbed bog moss, is a moss that is nearly cosmopolitan in distribution. It occurs in North America, Hispaniola, Venezuela, Eurasia, and New Zealand. In North America, it occurs across southern arctic, subboreal, and boreal regions from Alaska and British Columbia to Greenland and Quebec. Documentation of ribbed bog moss's distribution in the contiguous United States is probably incomplete. It is reported sporadically south to Washington, Wyoming, Georgia, and Virginia.
Sphagnum russowii, Russow's sphagnum or Russow's bogmoss, is a species of peat moss with a Holarctic distribution.
Sphagnum girgensohnii, the Girgensohn's bogmoss, Girgensohn's sphagnum or common green peat moss, is a species of peat moss with a Holarctic and Indo-Malesian distribution.
Sphagnum palustre, the prairie sphagnum or blunt-leaved bogmoss, is a species of peat moss from the genus Sphagnum, in the family Sphagnaceae. Like other mosses of this type it can soak up water up to the 30-fold amount of its own dry weight thanks to its elastic spiral fibers. S. palustre is rather frequent and is spread almost all over the world. It mainly grows in wet forests and—compared to other specimens of this genus—rarely grows in moors.
Astley and Bedford Mosses are areas of peat bog south of the Bridgewater Canal and north of the Liverpool and Manchester Railway. They are situated about 2 1⁄2 miles (4 km) south-east of Leigh, in Astley and Bedford, Greater Manchester, England. They are among the last remaining fragments of Chat Moss, the raised bog that once covered a large area, of around 10 2⁄3 square miles (28 km2), south Lancashire north of the River Mersey. Astley Moss was designated a Site of Special Scientific Interest in 1989. Astley and Bedford Mosses, along with Risley Moss and Holcroft Moss, are part of Manchester Mosses, a European Union designated Special Area of Conservation.
Sphagnum fuscum, the rusty bogmoss or rusty peat moss, is a peat moss found commonly in Norway and Sweden, and can be found scattered across North America, the United Kingdom, and in southern to eastern Europe.
The Alfred Bog is a domed peat bog in Eastern Ontario, Canada, about 7 kilometres (4.3 mi) south of Alfred and 70 kilometres (43 mi) east of Ottawa. The bog is considered the largest high-quality bog in Southern Ontario, and was designated by the Ontario Ministry of Natural Resources as a "Class 1 Wetland" and an "Area of Natural and Scientific Interest (ANSI)" in 1984. It is home to rare animal species and a healthy moose population.
