Cemaes Head
Cemaes Head (formerly Cemais, and historically anglicised as Cemmaes, Kemmaes or Kemmes) (Welsh: ''Pen Cemaes'' or ''Trwyn Cemaes'') is a headland and nature reserve in north Pembrokeshire. It lies in the community of St Dogmaels, within the Pembrokeshire Coast National Park. To the west and north it overlooks Cardigan Bay, and to the east Cardigan Island and the estuary of the River Teifi. Geology and structure Although the headland, when viewed from across the Teifi estuary, is relatively unspectacular, its cliffs, which are most dramatic on its north-western side, and reach over 575 ft (175m) in height, are the highest in Pembrokeshire. This makes the bays below the cliff tops largely inaccessible. The bedrock is composed of Silurian and (mostly) Ordovician sedimentary rocks, more specifically of Llanvirn-Caradoc black mudstone, i.e. some 470 million years old. This rock stretches southwest as far as Newport, but Cemaes Head lies north of the Ceibwr Bay Fault, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Conservancy Council
The Nature Conservancy Council (NCC) was a United Kingdom government agency responsible for designating and managing National Nature Reserves and other nature conservation areas in Great Britain between 1973 and 1991 (it did not cover Northern Ireland). Origin and Leadership The NCC was established by the Nature Conservancy Council Act 1973 and replaced the Nature Conservancy, established by Royal Charter in 1949. NCC's duties included: * Managing national nature reserves; * Providing advice on nature conservation to national and local government; * Notifying Sites of Special Scientific Interest; * Undertaking certain scientific research. Robert Edward Boote the former director of Nature Conservancy, having worked on revising its organisation was appointed by the Secretary of State for the Environment as the first Director General of the new NCC. He held this post until retiring in 1980 when Richard Charles Steele became Director General Structure The organisation was divi ...

Dyfed County Council
Dyfed County Council ( cy, Cyngor Sir Dyfed) was the county council of the non-metropolitan county of Dyfed in south west Wales. It operated between 1974 and 1996. The county council was based at County Hall, Carmarthen. History Dyfed County Council was created on 1 April 1974 under the Local Government Act 1972. It took over the functions of the three previous county councils which had covered the area: Cardiganshire, Carmarthenshire, and Pembrokeshire. Dyfed County Council was abolished under the Local Government (Wales) Act 1994, being replaced on 1 April 1996 by three unitary authorities: Carmarthenshire County Council, Ceredigion County Council, and Pembrokeshire County Council. These corresponded to the former counties which had been abolished 22 years earlier. The area of Dyfed became a preserved county, being used for some ceremonial purposes, but no longer having a county council. Political control The first election to the county council was held in April 1973, initia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Countryside Commission
The Countryside Commission (formally the Countryside Commission for England and Wales, then the Countryside Commission for England) was a statutory body in England and Wales, and later in England only. Its forerunner, the National Parks Commission, was established in 1949 by the National Parks and Access to the Countryside Act 1949 to co-ordinate government activity in relation to National Parks. This body became the Countryside Commission for England and Wales in 1968, when its duties were expanded to cover the countryside as a whole in England and Wales (a separate Countryside Commission for Scotland covered Scotland). In 1991 the Welsh part of the organisation was split off and amalgamated with the equivalent part of the Nature Conservancy Council (NCC) to become the Countryside Council for Wales. The rest of the organisation became the Countryside Commission for England – for the moment it remained separate from English Nature, as the English part of the NCC became. T ...

Wildlife Trust Of South And West Wales
The Wildlife Trust of South and West Wales (WTSWW) ( cy, Ymddiriedolaeth Natur De a Gorllewin Cymru) is a Wildlife Trust in south and west Wales, one of 46 such Trusts in the United Kingdom. History Forerunner of the WTSWW, the former West Wales Naturalists' Trust traces its origin to a meeting held in Haverfordwest in February 1938. It was convened by L. D. Whitehead, the Welsh industrialist and owner of Ramsey, and the naturalist and author R. M. Lockley, then living on Skokholm. Seventy-eight people were present at that inaugural meeting and on the motion of Mr. Hugh Lloyd-Philipps, of Dale Castle, the Pembrokeshire Bird Protection Society was formed. In 1943, the society was urged to promote the establishment of nature reserves in readiness for post-war conditions. A meeting in 1945 decided to widen its area, so as to cover the counties of Pembroke, Carmarthen, Cardigan, and Merioneth, in compliance with requests from those counties, and considered a selection of alterna ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Special Area Of Conservation
A Special Area of Conservation (SAC) is defined in the European Union's Habitats Directive (92/43/EEC), also known as the ''Directive on the Conservation of Natural Habitats and of Wild Fauna and Flora''. They are to protect the 220 habitats and approximately 1,000 species listed in annex I and II of the directive which are considered to be of European interest following criteria given in the directive. They must be chosen from the Sites of Community Importance by the member states and designated SAC by an act assuring the conservation measures of the natural habitat. SACs complement Special Protection Areas and together form a network of protected sites across the European Union called Natura 2000. This, in turn, is part of the Emerald network of Areas of Special Conservation Interest (ASCIs) under the Berne Convention. Assessment methodology in the United Kingdom Prior to being designated as a Special Area of Conservation (SAC), sites have been assessed under a two-stage process ...

Trig Point
A triangulation station, also known as a trigonometrical point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity. The nomenclature varies regionally: they are generally known as trigonometrical stations or triangulation stations in North America, trig points in the United Kingdom, trig pillars in Ireland, trig stations or trig points in Australia and New Zealand, and trig beacons in South Africa. Use The station is usually set up by a government with known coordinates and elevation published. Many stations are located on hilltops for the purposes of visibility. A graven metal plate on the top of a pillar may provide a mounting point for a theodolite or reflector, often using some form of kinematic coupling to ensure reproducible positioning. Trigonometrical stations are grouped together to form a network of triangulation. Positions of all land boundaries, roads, railways, bridges and other ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardigan, Ceredigion
Cardigan ( cy, Aberteifi, ) is both a town and a community in the county of Ceredigion, Wales. Positioned on the tidal reach of the River Teifi at the point where Ceredigion meets Pembrokeshire, Cardigan was the county town of the historic county of Cardiganshire. Cardigan is the second-largest town in Ceredigion. The largest town, Aberystwyth, is one of the two administrative centres; the other is Aberaeron. The settlement at Cardigan was developed around the Norman castle built in the late 11th or early 12th century. The castle was the location of the first National Eisteddfod in 1176. The town became an important port in the 18th century, but declined by the early 20th century owing to its shallow harbour. The castle underwent restoration in 2014. The population in 2001 was 4,203, reducing slightly to 4,184 at the 2011 census. Toponymy Cardigan is an anglicisation of the Welsh ' ("Ceredig's land"), the surrounding territory its Norman castle once controlled. Ceredig ...
