Drygarn Fawr
Drygarn Fawr is a mountain in the county of Powys, Wales. It is one of the highest summits in Mid Wales at above sea level. It lies to the south of the Elan Valley Reservoirs. Rising above the remote moorland plateau of the Cambrian Mountains, and to the west of the peaks of Radnor Forest, the summit is topped by two distinctive, large cairns. The mountain has a gentle, grassy, conical shape with a few rocks near the summit. Nearby are the summits of Gorllwyn, Y Gamriw, and Drum yr Eira all over 600m. Access There are two paths to the summit. From Llannerch Yrfa, a bridleway winds up through forests in the Nant y Fedw valley before skirting the southern edge of the mountain. An alternative route may be taken starting from Rhiwnant on the edge of the Caban Coch reservoir, one of the Elan Valley Reservoirs, and following the Nant Paradwys before turning off west towards the summit cairn. Both routes pass across wild moorland and peat bog A bog or bogland is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plynlimon
Pumlumon (historically anglicised in various ways including ''Plynlimon,'' Plinlimon and Plinlimmon) is the highest point of the Cambrian Mountains in Wales (taking a restricted definition of the Cambrian Mountains, excluding Snowdonia, the Berwyns and the Brecon Beacons), and the highest point in Mid Wales. It is a massif that dominates the surrounding countryside and is the highest point (county top) of Ceredigion (both the modern council area, and the historic county, also known as Cardiganshire). The highest point of the massif itself is Pen Pumlumon Fawr, which is above ordnance datum. Its other important peaks are Pen Pumlumon Arwystli, Y Garn, Pen Pumlumon Llygad-bychan and Pumlumon Fach. The longest river in Britain, the River Severn, has its source on the mountain, as do the rivers Wye and Rheidol. Folklore says there is a sleeping giant in Pumlumon. Etymology ''Plynlimon'' is anglicized from the Welsh name ''Pumlumon'', which is thought to mean "five t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moorland
Moorland or moor is a type of habitat found in upland areas in temperate grasslands, savannas, and shrublands and montane grasslands and shrublands biomes, characterised by low-growing vegetation on acidic soils. Moorland, nowadays, generally means uncultivated hill land (such as Dartmoor in South West England), but also includes low-lying wetlands (such as Sedgemoor, also South West England). It is closely related to heath, although experts disagree on what precisely distinguishes these types of vegetation. Generally, moor refers to highland and high rainfall zones, whereas heath refers to lowland zones which are more likely to be the result of human activity. Moorland habitats mostly occur in tropical Africa, northern and western Europe, and neotropical South America. Most of the world's moorlands are diverse ecosystems. In the extensive moorlands of the tropics, biodiversity can be extremely high. Moorland also bears a relationship to tundra (where the subsoil is permafros ...

Mountains And Hills Of Powys
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Elenydd
Elenydd () is an upland area of Mid Wales, extending across parts of northern and eastern Ceredigion and Powys between Aberystwyth and Rhayader. Elenydd is also a name given to the medieval commote of Cwmwd Deuddwr which covered approximately the same area. The area is an upland plateau of moorland and rough grazing within the Cambrian Mountains, source of the rivers Elan, Severn, Teifi, Towy and Wye. Elenydd is generally interpreted to mean the upland area between Pumlumon in the north and Mynydd Epynt in the south. The term " Desert of Wales" is sometimes applied to this or a wider area. Much of Elenydd is open land with public access, following the Countryside and Rights of Way Act 2000, widely known as the "CROW Act". Specific areas within Elenydd are designated as being of nature conservation importance. Etymology The name means the "area adjoining the Elan", which river name probably arises from Welsh ''elain'', meaning fawn or hind; -''ydd'' is a suffix denot ...

Peat Bog
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 t ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Rights Of Way In England And Wales
In England and Wales, other than in the 12 Inner London London boroughs, boroughs and the City of London, the right of way is a legally protected right of the public to pass and re-pass on specific paths. The law in England and Wales differs from Scots law in that rights of way exist only where they are so designated (or are able to be designated if not already), whereas in Scotland any route that meets certain conditions is rights of way in Scotland, defined as a right of way, and in addition, there is a general presumption of access to the countryside ("right to roam"). Private rights of way or easements also exist (see also Highways in England and Wales). Inner London Definitive maps of public rights of way have been compiled for all of England and Wales, as a result of the National Parks and Access to the Countryside Act 1949, except the 12 Inner London boroughs, which, along with the City of London, were not covered by the Act. Definitive maps exist for the Outer London bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cairn
A cairn is a man-made pile (or stack) of stones raised for a purpose, usually as a marker or as a burial mound. The word ''cairn'' comes from the gd, càrn (plural ). Cairns have been and are used for a broad variety of purposes. In prehistoric times, they were raised as markers, as memorials and as burial monuments (some of which contained chambers). In modern times, cairns are often raised as landmarks, especially to mark the summits of mountains. Cairns are also used as trail markers. They vary in size from small stone markers to entire artificial hills, and in complexity from loose conical rock piles to elaborate megalithic structures. Cairns may be painted or otherwise decorated, whether for increased visibility or for religious reasons. A variant is the inuksuk (plural inuksuit), used by the Inuit and other peoples of the Arctic region of North America. History Europe The building of cairns for various purposes goes back into prehistory in Eurasia, ranging in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radnor Forest
Radnor Forest ( cy, Fforest Clud) in the county of Radnorshire, Wales is a rock dome composed of Silurian shales, mudstones and limestone in Mid Wales. It is a forest in the medieval sense of the word (an area of land set aside for hunting). It lies within the Welsh Marches region since Offa's Dyke lies nearby to the east. The area lies to the north of the Black Mountains and to the east of the Cambrian Mountains. Hergest Ridge is immediately to the south-east of the area (just across the English border into Herefordshire), near the small town of Kington. The highest point in the area is Rhos Fawr a broad plateau which reaches , and is equipped with a trig point to mark the summit. A similar plateau adjoining to the east, Black Mixen is the only Nuttall to have a communications mast (a radio transmitter) on its summit. Geology The massif is formed from argillaceous rocks of Ludlow age, i.e. late Silurian around 425 million years ago. The strata are exposed around Harl ...

Plateau
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
