82-417: The Glades are a 750-acre (3.0 km) grouping of peat bogs resembling some Canadian bogs. The gladed land is highly acidic and supports plants commonly found at higher latitudes, including cranberries , sphagnum moss, skunk cabbage , and two carnivorous plants ( purple pitcher plant and sundew ). The Glades serve as the southernmost home of many of the plant species found there. The natural history of

164-480: A cover of sphagnum moss, bird-wheat moss , bog moss and reindeer lichen . Hummocks of these plants reach a height of 3 feet (0.91 m). Over top of these grow prostrate cranberry vines that bloom pink flowers in the summer, fruiting in late September. Most tree species occur in the "bog forest" habitat, which is composed primarily of a mixture of red spruce , eastern (or Canada) hemlock , yellow birch and red maple . The upland forests immediately surrounding

246-506: 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

328-496: 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

410-408: A short petiole . The winter twigs are distinctive among North American trees, being long and slender ( 15–20 millimetres or 5 ⁄ 8 – 3 ⁄ 4 inch by 2–3 mm or 3 ⁄ 32 – 1 ⁄ 8  in) with two rows of overlapping scales on the buds. Beech buds are distinctly thin and long, resembling cigars; this characteristic makes beech trees relatively easy to identify. The tree

492-490: A small increase in carbon dioxide uptake, meaning that it contributes to the permafrost carbon feedback . 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

574-539: 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

656-442: Is monoecious , with flowers of both sexes on the same tree. The fruit is a small, sharply-angled nut , borne in pairs in a soft-spined, four-lobed husk. It has two means of reproduction: one is through the usual dispersal of seedlings, and the other is through root sprouts, which grow into new trees. Trees in the southern half of the range are sometimes distinguished as a variety, F. grandifolia var. caroliniana , but this

738-535: Is a common practice to forest used peat bogs instead of giving them a chance to renew. This leads to lower levels of CO 2 storage than the original peat bog. Fagus grandifolia Fagus grandifolia var. typica Rehder Fagus grandifolia , the American beech or North American beech , is the only species of beech native to North America. Its current range comprises the eastern United States, isolated pockets of Mexico and southeastern Canada. Prior to

820-487: 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,

902-405: Is an important tree in forestry . The wood is hard and difficult to cut or split, although at 43 pounds per cubic foot (0.69 g/cm ) it is not exceptionally heavy, and it also rots relatively easily. It is used for a wide variety of purposes, most notably bentwood furniture as beech wood easily bends when steamed. It also makes high quality, long-burning firewood. Like European beech bark,

984-713: Is an uncommon evergreen shrub that was historically reported as abundant in the area. Nearby Yew Creek is presumably named for this species, as may be the broader Yew Mountains region in which the Glades are located. Browsing deer have reduced the number of Canada yew to such an extent that it is found only in scattered locations throughout its central Appalachian range. Many herbs with primarily northern distributions occur here, including oak fern , pod grass , Canada mayflower , mountain bindweed , marsh marigold , goldthread , swamp saxifrage , white wood sorrel , northern white violet , Jacob's ladder and buckbean . Jacob's ladder

1066-492: Is at its southernmost location. Grasses and sedges found here include blue joint , drooping wood reed grass , millet grass , rattlesnake mannagrass , interior sedge , and Fraser's sedge . Wild lilies in the Glades include yellow clintonia and white hellebore . Orchids include rose pogonia , lesser rattlesnake plantain , northern coralroot , and grass-pink orchid that are in full bloom in July. Northern (or early) coralroot

1148-477: Is available in considerable quantities. It is burned to produce heat and electricity . Peat provides around 4% of Finland's annual energy production. 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

1230-657: Is believed to have spanned the width of the North American continent all the way to the Pacific coast before the last ice age . Two subspecies are generally recognized: The genus name Fagus is Latin for "beech", and the specific epithet grandifolia comes from grandis "large" and folium "leaf", in reference to the American beech's larger leaves when compared to the European beech . The American beech

1312-551: 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

1394-423: Is either fibric, hemic, or sapric. Fibric peats are the least decomposed and consist of intact fibre. Hemic peats are partially decomposed and sapric are the most decomposed. Phragmites peat are composed of reed grass, Phragmites australis , and other grasses. It is denser than many other types of peat. Engineers may describe a soil as peat which has a relatively high percentage of organic material. This soil

1476-712: Is estimated that in 1997, peat and forest fires in Indonesia released between 0.81 and 2.57 gigatonnes (0.89 and 2.83 billion short tons; 0.80 and 2.53 billion long tons) of carbon; equivalent to 13–40 percent of the amount released by global fossil fuel burning, and greater than the carbon uptake of the world's biosphere. 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

1558-504: Is in a high valley, about 3,300 to 3,400 feet (1,005 to 1,036 meters) above sea level, surrounded by the Cranberry, Kennison, and Black Mountains. Five separate glades were identified and named in 1911: Big Glade (59 acres), Flag Glade (28 acres), Long Glade (20 acres), Round Glade (8 acres) and Little Glade (1 acre). The smallest, Little Glade, has since grown over and is no longer recognizable. Darlington's studies showed that

1640-427: Is indicated, an ample source appears to be present in the underlying Hinton Formation, a circumstance that also has significant implications for the Glades' flora. The area is not entirely a glade, but a bog or wetland covered with all sorts of decaying vegetation. The peat and decaying organic matter is more than ten feet thick under the dense plant cover. The ground is not as much as quicksand or swampy, but spongy. It

1722-412: Is known for frequent weather changes. Generally speaking, the area is cool and wet, comparable to the climates of New England and Canada. This is due to its high elevation and the surrounding higher mountains forming a bowl, draining their cool air downhill into the Glades. The potential for frost exists year-round at Cranberry Glades. In some years, the frost-free period has been as short as 81 days. Still,

1804-405: Is more often associated with sugar maple (forming the beech–maple climax community ), yellow birch , and eastern hemlock , typically on moist, well-drained slopes and rich bottomlands. Near its southern limit, it often shares canopy dominance with southern magnolia . Although it has a reputation for slow growth (sometimes only 13 feet in 20 years), rich soil and ample moisture will greatly speed

1886-521: Is native to eastern North America, from Nova Scotia west to southern Ontario in southeastern Canada, west to Wisconsin and south to eastern Texas and northern Florida in the United States, as well as the states of Hidalgo, Veracruz, Tamaulipas, Puebla, San Luis Potosí, and Tabasco in Mexico. Mature specimens are rare in lowland areas as early settlers quickly discovered that the presence of

1968-595: Is not considered distinct in the Flora of North America. The Mexican beech ( F. grandifolia subsp. mexicana ), native to the mountains of central Mexico , is closely related, and is treated as a subspecies of American beech, but some botanists classify it as a distinct species. The only Fagus species found in the Western Hemisphere (assuming the Mexican subspecies is treated as such), F. grandifolia

2050-413: 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

2132-456: Is probably at its southernmost location in the eastern United States. Many animals that live in the Glades are at their southernmost breeding grounds, including birds such as the Swainson's and hermit thrushes , Nashville and mourning warblers , and purple finches . Other, less exotic, birds like ravens and hawks are common. Other familiar animals including white-tailed deer inhabit

2214-483: Is problematic because it exhibits poor consolidation properties—it cannot be easily compacted to serve as a stable foundation to support loads, such as roads or buildings. 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

2296-506: Is retaining moisture in container soil when it is dry while preventing the excess water from killing roots when it is wet. 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

2378-635: Is sometimes used in freshwater aquaria . It is seen most commonly in soft water or blackwater river systems such as those mimicking the Amazon River basin. 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

2460-769: Is taken. In June 2002, the United Nations Development Programme launched the Wetlands Ecosystem and Tropical Peat Swamp Forest Rehabilitation Project. This project was targeted to last for five years, and brings together the efforts of various non-government organisations. In November 2002, the International Peatland (formerly Peat) Society (IPS) and the International Mire Conservation Group (IMCG) published guidelines on

2542-565: Is the average depth of the boreal [northern] peatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO 2 emissions). 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

2624-401: Is the bioaccumulation of metals concentrated in the peat. Accumulated mercury is of significant environmental concern. Large areas of organic wetland (peat) soils are currently drained for agriculture, forestry and peat extraction (i.e. through canals ). This process is taking place all over the world. This not only destroys the habitat of many species but also heavily fuels climate change. As

2706-407: Is the most efficient carbon sink on the planet , because peatland plants capture carbon dioxide (CO 2 ) 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

2788-456: The "Wise Use of Mires and Peatlands – Backgrounds and Principles including a framework for decision-making" . This publication aims to develop mechanisms that can balance the conflicting demands on the global peatland heritage to ensure its wise use to meet the needs of humankind. In June 2008, the IPS published the book Peatlands and Climate Change , summarising the currently available knowledge on

2870-819: The Falkland Islands and Indonesia ( Kalimantan [Sungai Putri, Danau Siawan, Sungai Tolak], Rasau Jaya ( West Kalimantan ) and Sumatra ). Indonesia has more tropical peatlands and mangrove forests than any other nation on earth, but Indonesia is losing wetlands by 100,000 hectares (250,000 acres) per year. 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. Peat can be used as fuel once dried. Traditionally, peat

2952-996: The West Siberian Lowland , the Hudson Bay Lowlands and the Mackenzie River Valley. There is less peat in the Southern Hemisphere, in part because there is less land. The world's largest tropical peatland is located in Africa (the Democratic Republic of Congo). In addition, the vast Magellanic Moorland in South America (Southern Patagonia / Tierra del Fuego ) is an extensive peat-dominated landscape. Peat can be found in New Zealand , Kerguelen ,

3034-461: The last glacial retreat . Among these are two unusual species of carnivorous plants that thrive in the area—the purple pitcher plant and native sundew . They evolved carnivorous habits because of the scarce root food in the spongy soil. Two very rare boreal plants— bog rosemary and buckbean —live in the Big Glade. Much of the area provides a home for many species of mosses . These include

3116-597: The tanning properties of the acidic water, as well as by the antibiotic properties of the organic component sphagnan. A famous example is the Tollund Man in Denmark. Having been discovered in 1950 after being mistaken for a recent murder victim, he was exhumed for scientific purposes and dated to have lived during the 4th century BC. Before that, another bog body, the Elling Woman , had been discovered in 1938 in

3198-468: The American beech and also to the related European beech . The beech leaf-miner weevil , a species native to Europe, has been identified in North America as a cause of defoliation of American beech trees. American beech trees have small gaps and crevices at the base of their trunks in which the pest overwinter before eventually making their way to the buds of the trees and finally laying eggs on

3280-472: The American beech bark is smooth and uniform, making it an attraction for people to carve names, dates, decorative symbols such as love hearts or gang identifiers, and other material into its surface. One such beech tree in Louisville, Kentucky , in what is now the southern part of Iroquois Park , bore the legend " D. Boone kill a Bar 1803." The beech finally fell over in 1916 during a storm; its age

3362-583: The European beech scale insect, Cryptococcus fagisuga , attacks the bark, creating a wound that is then infected by Neonectria ditissima or Neonectria faginata , two species of fungi . This causes a canker to develop and the tree is eventually killed. Beech leaf disease is caused by the nematode Litylenchus crenatae mccannii . It was discovered in Ohio in 2012 and identified as far south as Virginia in 2022. Beech leaf disease causes severe damage to

Cranberry Glades - Misplaced Pages Continue

3444-485: The Glades has been traced back at least 12,200 years. Apparently, a forest of conifer-northern hardwoods replaced tundra with the end of the Last Glacial Period . Over time the Glades formed into what it is today. Now, most of the bog is underlain by peat that is up to 10 feet (3.0 m) thick. Under the peat is a layer of algal ooze, underlain by marl . Since a limestone source in the surrounding rocks

3526-414: The Glades were formed by easily eroding rocks in the basin and more resistant rock at its lower end. This effectively prevented down-cutting and maintained a low gradient in the valley. This resulted in an elevation of 3,400 ft (1,000 m) at the upper end and 3,350 ft (1,020 m) at the back, eliminating the possibility of origin by water impoundment. The water from the Glades drains to form

3608-476: The Glades. Black bears have been seen in the skunk cabbage growing along the boardwalk. In the evening, you have a good chance of hearing beavers working; they are mostly inactive during the day. It is hard to see the beavers because of little light, and they are dark colored. They also reside submerged or are building their homes. Like many of the adjoining areas high in the Alleghenies , Cranberry Glades

3690-548: The West Siberian peatland. Palsa mires have a rich bird life and are an EU-red listed habitat, and in Canada riparian peat banks are used as maternity sites for polar bears. Natural peatlands also have many species of wild orchids and carnivorous plants. For more on biological communities, see wetland , bog or fen . Around half of the area of northern peatlands is permafrost -affected, and this area represents around

3772-422: The average summer high is in roughly 74 °F-82 °F (23 °C-28 °C). Mid-winter temperatures record as low as −26 °F (−32 °C), and the area often sees heavy snow. Peat 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,

3854-522: The bogland remains constantly wet which helps promote peat production. Most modern peat bogs formed 12,000 years ago in high latitudes after the glaciers retreated at the end of the last ice age . Peat usually accumulates slowly at the rate of about a millimetre per year. The estimated carbon content is 415 gigatonnes (457 billion short tons) (northern peatlands), 50 Gt (55 billion short tons) ( tropical peatlands ) and 15 Gt (17 billion short tons) (South America). Peat material

3936-550: The capital of Moscow with a toxic smoke blanket . The situation remained critical until the end of August 2010. In June 2019, despite some forest fire prevention methods being put in place, peat fires in the Arctic emitted 50 megatonnes (55 million short tons; 49 million long tons) of CO 2 , which is equal to Sweden's total annual emissions. The peat fires are linked to climate change, as they are much more likely to occur nowadays due to this effect. Peat "hags" are

4018-428: The concept of peat archives, a phrase coined by influential peatland scientist Harry Godwin in 1981. In a peat profile there is a fossilized record of changes over time in the vegetation, pollen, spores, animals (from microscopic to the giant elk), and archaeological remains that have been deposited in place, as well as pollen, spores and particles brought in by wind and weather. These remains are collectively termed

4100-455: The fastest-growing top emitters. This estimate excludes emissions from peat fires (conservative estimates amount to at least 4,000 Mton/CO 2 -eq./yr for south-east Asia). With 174 Mton/CO 2 -eq./yr, the EU is after Indonesia (500 Mton) and before Russia (161 Mton), the world's second-largest emitter of drainage-related peatland CO 2 (excl. extracted peat and fires). Total CO 2 emissions from

4264-518: The glacial maximum of the Pleistocene epoch , the tree flourished over most of North America, reaching California. Fagus grandifolia is a large deciduous tree growing to 16–35 metres (52–115 feet) tall, with smooth, silver-gray bark . The leaves are dark green, simple and sparsely-toothed with small teeth that terminate each vein, 6–12 centimetres ( 2 + 1 ⁄ 4 – 4 + 3 ⁄ 4 inches) long (rarely 15 cm or 6 in), with

4346-603: The ground. In North America, peat fires can occur during severe droughts throughout their occurrence, from boreal forests in Canada to swamps and fens in the subtropical southern Florida Everglades . Once a fire has burnt through the area, hollows in the peat are burnt out, and hummocks are desiccated but can contribute to Sphagnum recolonization. In the summer of 2010, an unusually high heat wave of up to 40 °C (104 °F) ignited large deposits of peat in Central Russia, burning thousands of houses and covering

4428-572: The headwaters of the Cranberry River , a popular trout stream joined by the Yew and Charles Creeks. It starts at about 4,600 feet (1,400 m) elevation, and then it meanders through the glades and recedes through a narrow gap between Kennison and Black Mountains. It then joins the Gauley River 25 miles (40 km) down the mountains at about 1,920 feet (590 m). The Glades have been

4510-604: The land and freshwater surface of the planet. In these ecosystems are found one third of the world's soil carbon and 10% of global freshwater resources. These ecosystems are characterized by the unique ability to accumulate and store dead organic matter from Sphagnum and many other non-moss species, as peat, under conditions of almost permanent water saturation. Peatlands are adapted to the extreme conditions of high water and low oxygen content, of toxic elements and low availability of plant nutrients. Their water chemistry varies from alkaline to acidic. Peatlands occur on all continents, from

4592-509: The main source of water for large cities, including Dublin. Peat wetlands also used to have a degree of metallurgical importance in the Early Middle Ages , being the primary source of bog iron used to create swords and armour. Many peat swamps along the coast of Malaysia serve as a natural means of flood mitigation, with any overflow being absorbed by the peat, provided forests are still present to prevent peat fires. Peat

4674-540: The peat archives. 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

4756-433: The peat holds water. This slowly creates wetter conditions that allow the area of wetland to expand. Peatland features can include ponds, ridges and raised bogs . The characteristics of some bog plants actively promote bog formation. For example, sphagnum mosses actively secrete tannins , which preserve organic material. Sphagnum also have special water-retaining cells, known as hyaline cells, which can release water ensuring

4838-683: The potential human impacts on the biogeochemical cycle of mercury, for example. Over the years, different dating models and technologies for measuring date sediments and peat profiles accumulated over the last 100–150 years, have been used, including the widely used vertical distribution of 210Pb, the inductively coupled plasma mass spectrometry (ICP-SMS), and more recently the initial penetration (IP). Naturally mummified human bodies, often called " bog bodies " have been found in various places in Scotland, England, Ireland, and especially northern Germany and Denmark. They are almost perfectly preserved by

4920-441: The presence of a heat source (e.g., a wildfire penetrating the subsurface), it smoulders. These smouldering fires can burn undetected for very long periods of time (months, years, and even centuries) propagating in a creeping fashion through the underground peat layer. Despite the damage that the burning of raw peat can cause, bogs are naturally subject to wildfires and depend on the wildfires to keep woody competition from lowering

5002-519: The primary foods of the now-extinct passenger pigeon ; the clearing of beech and oak forests is pointed to as one of the major factors that may have contributed to the bird's extinction. Some Lepidoptera caterpillars feed on beeches. Deer occasionally browse on beech foliage, but it is not a preferred food. Beech bark disease has become a major killer of beech trees in the Northeastern United States. This disease occurs when

5084-624: The process up. American beech favours a well-watered, but also well-drained spot and is intolerant of urban pollution, salt, and soil compaction. It also casts heavy shade and is an extremely thirsty tree with high moisture requirements compared to oaks, so it has a dense, shallow root system. The mast (crop of nuts) from American beech provides food for numerous species of animals. Among vertebrates alone, these include various birds including ruffed grouse and wild turkeys, raccoons, foxes, white-tailed deer, rabbits, squirrels, opossums, pheasants, black bears, and porcupines. Beech nuts were one of

5166-640: The rate of decomposition. Peat properties such as organic matter content and saturated hydraulic conductivity can exhibit high spatial heterogeneity . Peatlands, particularly bogs , are the primary source of peat; although less common, other wetlands, including fens , pocosins and peat swamp forests , also deposit peat. Landscapes covered in peat are home to specific kinds of plants, including Sphagnum moss, ericaceous shrubs and sedges . Because organic matter accumulates over thousands of years, peat deposits provide records of past vegetation and climate by preserving plant remains, such as pollen. This allows

5248-545: The reconstruction of past environments and the study of land-use changes. Peat is used by gardeners and for horticulture in certain parts of the world, but this is being banned in some places. By volume, there are about 4 trillion cubic metres of peat in the world. Over time, the formation of peat is often the first step in the geological formation of fossil fuels such as coal , particularly low-grade coal such as lignite . The peatland ecosystem covers 3.7 million square kilometres (1.4 million square miles) and

5330-614: The rewetting of peatlands and revegetation of native species. This acts to mitigate carbon release in the short term before the new growth of vegetation provides a new source of organic litter to fuel the peat formation in the long term. UNEP is supporting peatland restoration in Indonesia. Latvia has been the biggest exporter of peat in the world by volume, providing more than 19.9% of the world's volume, followed only by Canada with 13% in 2022. In 2020, Latvia exported 1.97 million tons of peat, followed by Germany with 1.5 and Canada with 1.42 million tons. Nevertheless, although first in

5412-562: The rise, particularly in the UK, peat is still used as raw material for horticulture in some other European countries, Canada, as well as parts of the United States. Peatland can also be an essential source of drinking water , providing nearly 4% of all potable water stored in reservoirs . In the UK, 43% of the population receives drinking water sourced from peatlands, with the number climbing to 68% in Ireland. Catchments containing peatlands are

5494-564: The same bog about 60 metres (200 ft) from the Tollund Man. She is believed to have lived during the late 3rd century BC and was a ritual sacrifice. In the Bronze and Iron Ages, people used peat bogs for rituals to nature gods and spirits. The distinctive ecological conditions of peat wetlands provide a habitat for distinctive fauna and flora. For example, whooping cranes nest in North American peatlands, whilst Siberian cranes nest in

5576-511: The state whilst 23% belong to the municipalities Bogs in Latvia are considered important habitats due to their ecological values, and up to 128,000 hectares, or 40% of the areas in the territory, are protected by environmental laws. The most famous national parks and reserves are the Ķemeri National Park , Cenas tīrelis and Teiči Nature Reserve . The climate, geography and environment of Finland favours bog and peat bog formation. Thus, peat

5658-581: The subject of much scientific study, especially during the 1930s, 1940s and 1950s. Professor Maurice Brooks conducted studies in 1930, 1934, and 1945. The work of Strausbaugh (1934), Darlington (1943), and Core (1955) followed. In 1974, the Cranberry Glades Botanical Area was designated a National Natural Landmark . Many of the plants found in the Glades resemble those in the northern region of North America. They are descendants of seeds that took root over 10,000 years ago before

5740-450: The topic. In 2010, IPS presented a " Strategy for Responsible Peatland Management ", which can be applied worldwide for decision-making. Peat extraction is forbidden in Chile since April 2024. Often, restoration is done by blocking drainage channels in the peatland, and allowing natural vegetation to recover. Rehabilitation projects undertaken in North America and Europe usually focus on

5822-439: The tree indicated good farmland. The American beech is a shade-tolerant species, commonly found in forests in the final stage of succession . Few trees in its natural range other than sugar maple match it for shade tolerance. Ecological succession is essentially the process of forests changing their composition through time; it is a pattern of events often observed on disturbed sites. Although sometimes found in pure stands, it

5904-639: The tree is about 40 years old. Large crops are produced by 60 years. The oldest documented tree is 246 years old. The fruit is a triangle-shaped shell containing 2–3 nuts inside, but many of them do not fill in, especially on solitary trees. Beech nuts are sweet and nutritious, can be eaten raw by wildlife and humans, or can be cooked. They can also be roasted and ground into a coffee substitute . The leaves are edible when cooked. The inner bark can be dried and pulverized into bread flour as an emergency food. Numerous place names in North America are named Beechwood . In John Steinbeck 's novel East of Eden ,

5986-409: The trees. Despite their high moisture needs, beeches succumb to flooding easily and their thin bark invites damage from animals, fire, and human activities. Late spring frosts can cause complete defoliation of the tree, although they typically recover by using reserve pools of sugar. The trunks of mature beeches often rot and develop cavities that are used by wildlife for habitation. American beech

6068-410: The tropical to boreal and Arctic zones from sea level to high alpine conditions. A more recent estimate from an improved global peatland map, PEATMAP, based on a meta-analysis of geospatial information at global, regional and national levels puts global coverage slightly higher than earlier peatland inventories at 4.23 million square kilometres (1.63 million square miles) approximately 2.84% of

6150-402: The underside of the leaves. Once hatched, the larvae mine the leaves, causing destruction to the foliage. Beech blight aphids colonize branches of the tree, but without serious harm to otherwise healthy trees. Below these colonies, deposits of sooty mold develop caused by the fungus Scorias spongiosa growing saprophytically on the honeydew the insects exude. This is also harmless to

6232-812: The water table and shading out many bog plants. Several families of plants including the carnivorous Sarracenia (trumpet pitcher), Dionaea (Venus flytrap), Utricularia (bladderworts) and non-carnivorous plants such as the sandhills lily , toothache grass and many species of orchid are now threatened and in some cases endangered from the combined forces of human drainage, negligence and absence of fire. The recent burning of peat bogs in Indonesia, with their large and deep growths containing more than 50 billion tonnes (55 billion short tons; 49 billion long tons) of carbon, has contributed to increases in world carbon dioxide levels. Peat deposits in Southeast Asia could be destroyed by 2040. It

6314-714: The water yellow or brown due to the leaching of tannins . Peat is widely used in balneotherapy (the use of bathing to treat disease). Many traditional spa treatments include peat as part of peloids . Such health treatments have an enduring tradition in European countries, including Poland, the Czech Republic, Germany and Austria. Some of these old spas date back to the 18th century and are still active today. The most common types of peat application in balneotherapy are peat muds , poultices and suspension baths . Authors Rydin and Jeglum in Biology of Habitats described

6396-469: The wetlands are dominated by these same species, but also include American beech , sugar maple , black cherry , American basswood , white ash , yellow buckeye , black birch , cucumber tree , Fraser magnolia , and northern red oak . The shrub layer , unlike the tree layer , is relatively species-rich. This is a consequence of the widespread presence of low- to medium-height woody plants throughout shrub swamps , forest habitats, and open glades . In

6478-436: The world by volume, in monetary terms, Latvian comes second in the world behind Canada . As an example, Latvia's income from exports was US$ 237 million. Latvia's peat deposits have been estimated to equal 1.7 billion tons. Latvia, as Finland due its climate has several peat bogs, which account for 9.9% of the country's territory. More than two thirds of the licensed areas for peat extraction are state-owned; 55% belong to

6560-479: The world land area. In Europe, peatlands extend to about 515,000 km (199,000 sq mi). About 60% of the world's wetlands are made of peat. Peat deposits are found in many places around the world, including northern Europe and North America. The North American peat deposits are principally found in Canada and the Northern United States. Some of the world's largest peatlands include

6642-466: The worldwide 500,000 km of degraded peatland may exceed 2.0 Gtons (including emissions from peat fires), which is almost 6% of all global carbon emissions. Peat can be a major fire hazard and is not extinguished by light rain. Peat fires may burn for great lengths of time, or smoulder underground and reignite after winter if an oxygen source is present. Peat has a high carbon content and can burn under low moisture conditions. Once ignited by

6724-548: Was estimated at around 325 years. Its trunk is now on display at the Filson Historical Society . It is sometimes planted as an ornamental tree, but even within its native area, it is planted much less often than the European beech. Although American beech can handle hotter climates, its European cousin is faster-growing and more pollution-tolerant, in addition to being easier to propagate. American beech does not produce significant quantities of nuts until
