Pembrokeshire, South Wales
Pembrokeshire ( ; ) is a county in the south-west of Wales. It is bordered by Carmarthenshire to the east, Ceredigion to the northeast, and otherwise by the sea. Haverfordwest is the largest town and administrative headquarters of Pembrokeshire County Council. The county is generally sparsely populated and rural, with an area of and a population of 123,400. After Haverfordwest, the largest settlements are Milford Haven (13,907), Pembroke Dock (9,753), and Pembroke (7,552). St Davids (1,841) is a city, the smallest by population in the UK. Welsh is spoken by 17.2 percent of the population, and for historic reasons is more widely spoken in the north of the county than in the south. Pembrokeshire's coast is its most dramatic geographic feature, created by the complex geology of the area. It is a varied landscape which includes high sea cliffs, wide sandy beaches, the large natural harbour of Milford Haven, and several offshore islands which are home to seabird colonies. Most ...

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 reserve (United Kingdom), national nature reserves, Ramsar Convention, Ramsar sites, Special Protection Areas, and Special Area of Conservation, Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their Biology, biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or Physical geography, physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Resources Wales
Natural Resources Wales () is a Welsh Government sponsored body, which became operational from 1 April 2013, when it took over the management of the natural resources of Wales. It was formed from a merger of the Countryside Council for Wales, Environment Agency Wales, and the Forestry Commission, Forestry Commission Wales, and also assumed some other roles formerly performed by the Welsh Government. Roles and responsibilities Purpose NRW's purpose is to "pursue sustainable management of natural resources” and “apply the principles of sustainable management of natural resources” as stated in the Environment (Wales) Act 2016. Remit NRW receives a Remit Letter at the start of each financial year setting out what the Welsh Government wants it to achieve during that year. Its main responsibilities are: * Adviser: principal adviser to Welsh Government, and adviser to industry and the wider public and voluntary sector, and communicator about issues relating to the environmen ...

Wenlock (Silurian)
The Wenlock Epoch (sometimes referred to as the Wenlockian) is the second epoch of the Silurian. It is preceded by the Llandovery Epoch and followed by the Ludlow Epoch. Radiometric dates constrain the Wenlockian between and million years ago. Naming and history The Wenlock is named after Wenlock Edge, an outcrop of rocks near the town of Much Wenlock in Shropshire ( West Midlands, United Kingdom). The name was first used in the term "Wenlock and Dudley rocks" by Roderick Murchison in 1834 to refer to the limestones and underlying shales that underlay what he termed the "Ludlow rocks". He later modified this term to simply the "Wenlock rocks" in his book, ''The Silurian System'' in 1839. Definition and subdivision The Wenlock's beginning is defined by the lower boundary (or GSSP) of the Sheinwoodian. The end is defined as the base (or GSSP A Global Boundary Stratotype Section and Point (GSSP), sometimes referred to as a golden spike, is an internationally agreed upo ...

Silurian
The Silurian ( ) is a geologic period and system spanning 23.5 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods ( myriapods, arachnids and hexapods) ...

Variscan Orogeny
The Variscan orogeny, or Hercynian orogeny, was a geologic mountain-building event caused by Late Paleozoic continental collision between Euramerica (Laurussia) and Gondwana to form the supercontinent of Pangaea. Nomenclature The name ''Variscan'' comes from the Medieval Latin name for the district '' Variscia'', the home of a Germanic tribe, the Varisci; Eduard Suess, professor of geology at the University of Vienna, coined the term in 1880. ( Variscite, a rare green mineral first discovered in the Vogtland district of Saxony in Germany, which is in the Variscan belt, has the same etymology.) ''Hercynian'', on the other hand, derives from the Hercynian Forest. Both words were descriptive terms of strike directions observed by geologists in the field, ''variscan'' for southwest to northeast, ''hercynian'' for northwest to southeast. The ''variscan'' direction reflected the direction of ancient fold belts cropping out throughout Germany and adjacent countries and the meanin ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Limonium Binervosum
''Limonium binervosum'', commonly known as rock sea-lavender, is an aggregate species in the family Plumbaginaceae. Despite the common name, rock sea-lavender is not related to the lavenders or to rosemary but is a perennial herb with small violet-blue flowers with five petals in clusters. Eight rock sea-lavenders are endemic to Britain and Guernsey and the taxonomy was reviewed in 1986 to include a range of subspecies. Wirral web site accessed 2008-05-03 Growing 10–70 cm tall from a rhizome, ''Limonium binervosum'' flourishes in saline soils, so are therefore common near the western coasts and in salt marshes, and also on saline, gypsum and alkaline soils such as found on Flat Holm island in Wales Wales ( ) is a Countries of the United Kingdom, country that is part of the United Kingdom.
