Raised Bog
Raised bogs, also called ombrotrophic bogs, are acidic, wet habitats that are poor in mineral salts and are home to flora and fauna that can cope with such extreme conditions. Raised bogs, unlike fens, are exclusively fed by precipitation ( ombrotrophy) and from mineral salts introduced from the air. They thus represent a special type of bog, hydrologically, ecologically and in terms of their development history, in which the growth of peat mosses over centuries or millennia plays a decisive role. They also differ in character from blanket bogs which are much thinner and occur in wetter, cloudier climatic zones. Raised bogs are very threatened by peat cutting and pollution by mineral salts from the surrounding land (due to agriculture and industry). The last great raised bog regions are found in western Siberia and Canada. Terminology The term raised bog derives from the fact that this type of bog rises in height over time as a result of peat formation. They are like sponges o ...

Sphagnum
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat). 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.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and Calcifuges, ericaceous shrubs, as well as orchids and carnivorous plant ...

Diepholz (district)
Diepholz () is a district in Lower Saxony, Germany. It is bounded by (from the northeast and clockwise) the districts of Verden, Nienburg, Minden-Lübbecke (in North Rhine-Westphalia), Osnabrück, Vechta and Oldenburg, and by the cities of Delmenhorst and Bremen. The most populous municipality is Stuhr at the border to Bremen. History From the 12th century to 1585 Diepholz was a sovereign Noble Lordship, later County, within the Holy Roman Empire that was ruled over by the Noble Lords, later Counts, of Diepholz. At the beginning of the 16th century there was great pressure from the powerful duchy of Brunswick-Lüneburg, which tried to annex the smaller states.

Bogs Of Lower Saxony
A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials often mosses, typically 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.Watson, Geraldine Ellis (2000) ''Big Thicket Plant Ecology: An Introduction'', Third Edition (Temple Big Thicket Series #5). University of North Texas Press. Denton, Texas. 152 pp. Texas Parks and Wildlife. Ecological Mapping systems of Texas: West Gulf Coastal Plain Seepage Swamp and Baygall'. Retrieved 7 July 2020 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. Bogs occur where the water at the ground surface is acidic and low in nutrients. In contrast to fens, they derive most of th ...

Erica (plant)
''Erica'' is a genus of roughly 857 species of flowering plants in the family Ericaceae. The English common names heath and heather are shared by some closely related genera of similar appearance. The genus ''Calluna'' was formerly included in ''Erica'' – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. ''Erica'' is sometimes referred to as "winter (or spring) heather" to distinguish it from ''Calluna'' "summer (or autumn) heather". Etymology The Latin word ''erica'' means "heath" or "broom". It is believed that Pliny adapted ''erica'' from Ancient Greek ἐρείκη. The expected Anglo-Latin pronunciation, , may be given in dictionaries (''OED'': "Erica"), but is more commonly heard. Description Most of the species of ''Erica'' are small shrubs from high, though some are taller; the tallest are '' E. arborea'' (tree heath) and '' E. scoparia'' (besom heath), both of which can reach up ...

Peat
Peat (), also 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 and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (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 , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 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. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erica Tetralix
''Erica tetralix'', the cross-leaved heath, is a species of flowering plant in the family Ericaceae, native to western Europe, from southern Portugal to central Norway, as well as a number of boggy regions further from the coast in Central Europe such as Austria and Switzerland. In bogs, wet heaths and damp coniferous woodland, ''E. tetralix'' can become a dominant part of the flora. It has also been introduced to parts of North America. Description It is a perennial subshrub with small pink bell-shaped drooping flowers borne in compact clusters at the ends of its shoots, and leaves in whorls of four (whence the name). The flowers appear in summer and autumn. The distinction between ''E. tetralix'' and the related species ''Erica cinerea'' is that the linear leaves are usually glandular and in whorls of four, while those of ''Erica cinerea'' are glabrous and borne in whorls of three. The leaves of ''Calluna vulgaris'' are much smaller and scale-like and borne in opposite and dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottongrass
''Eriophorum'' (cottongrass, cotton-grass or cottonsedge) is a genus of flowering plants in the family Cyperaceae, the sedge family. They are found throughout the arctic, subarctic, and temperate portions of the Northern Hemisphere in acid bog habitats, being particularly abundant in Arctic tundra regions.Flora Europaea''Eriophorum''/ref> They are herbaceous perennial plants with slender, grass-like leaves. The seed heads are covered in a fluffy mass of cotton-like fibers which are carried on the wind to aid dispersal. The cotton grass also maintains a height of 12 inches and around 2 inches in water. In cold Arctic regions, these masses of translucent fibres also serve as 'down' – increasing the temperature of the reproductive organs during the Arctic summer by trapping solar radiation. Paper and the wicks of candles have been made of its fiber, and pillows stuffed with the same material. The leaves were formerly used in treating diarrhea, and the spongy pith of the stem for ...

Drainage
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Geotextiles New storm water drainage systems incorporate geotextile filters that retain and prevent fine grains of soil from passing into and clogging the drain. Geotextiles are synthetic textile fabrics specially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Region
A natural region (landscape unit) is a basic geographic unit. Usually, it is a region which is distinguished by its common natural features of geography, geology, and climate. From the ecology, ecological point of view, the naturally occurring flora and fauna of the region are likely to be influenced by its geographical and geological factors, such as soil and water resources, water availability, in a significant manner. Thus most natural regions are homogeneous ecosystems. Human impact can be an important factor in the shaping and destiny of a particular natural region. Main terms The concept "natural region" is a large basic geographical unit, like the vast boreal forest region. The term may also be used generically, like in alpine tundra, or specifically to refer to a particular place. The term is particularly useful where there is no corresponding or coterminous official region. The Fens of eastern England, the Thai highlands, and the Pays de Bray in Normandy, are examples o ...

Minden-Lübbecke
Minden-Lübbecke is a ''Kreis'' (district) in the northeastern part of North Rhine-Westphalia, Germany. Neighboring districts are Diepholz, Nienburg, Schaumburg, Lippe, Herford, Osnabrück. Geography This is the northernmost district of North Rhine-Westphalia. It protrudes into Lower Saxon territory. The Weser River enters the district in the southeast and leaves to the north. In the south of the district the river runs through a narrow gorge, which is formed by two mountain chains, the Wiehen Hills in the west and the Wesergebirge in the east. This gorge is called Porta Westfalica, since it marks the ancient border of Westphalia. History Minden-Lübbecke is roughly identical with the medieval Bishopric of Minden. At its biggest extent in the 13th century, it later lost territory until it came finally to be around the size of today's district. In the 17th century the principality came into the possession of Brandenburg and thus Prussia. Lost for a time to Napoleonic France, it ...
