Middleholm
Middleholm, also known as Midland Isle, is a small island lying off southwest Pembrokeshire in Wales, between the island of Skomer and the mainland in the community of Marloes and St Brides. It is roughly circular with a diameter of about and an area of . It is separated from the mainland by Jack Sound and from Skomer by Little Sound. History The name Middleholm was documented in 1325 in the reign of Edward III, when ferreters were paid for catching rabbits. The island has been in use for considerably longer, with traces of Iron Age walling, and may have been used for summer grazing, despite the lack of natural fresh water. Since 1966, when the rabbit population was killed by myxomatosis, the island has been ungrazed. The name Midland Isle has been used at least as far back as 1578, when it was abbreviated in Latin as ''Midlan Insul''. This name was also used in 1833, when it was cited in Lewis's ''A Topographical Dictionary of Wales''. Modern Ordnance Survey maps use the latter ...

Skomer
Skomer () or Skomer Island is an island off the coast of Pembrokeshire, in the community of Marloes and St Brides in west Wales. It is well known for its wildlife: around half the world's population of Manx shearwaters nest on the island, the Atlantic puffin colony is the largest in southern Britain, and the Skomer vole (a subspecies of the bank vole) is unique to the island. Skomer is a national nature reserve (United Kingdom), national nature reserve, a Site of Special Scientific Interest and a Special Protection Area. It is surrounded by a marine nature reserve and is managed by the Wildlife Trust of South and West Wales. Skomer is known for its archaeological interest: stone circles, standing stone and remains of prehistoric houses. Much of the island has been designated an ancient monument. Description The island has an area of . Its highest point is above sea level at Gorse Hill, while the majority of the island sits at around above sea level. Skomer is intersected by ...

Jack Sound
Jack Sound is a treacherous body of water about wide between the island of Skomer and the Pembrokeshire mainland that contains numerous reefs and a tidal race of up to 6 knots. It is used by boats to avoid a three-mile detour around the island, and has its share of sunken shipwrecks. The most popular wreck for divers is the MV ''Lucy'', which sank in good condition in February 1967 after being abandoned by its crew owing to its cargo of calcium carbide. The Netherlands-registered coaster, , was en route from Uddevalla, Sweden to Barry. The sound is part of the Skomer Marine Conservation Zone Skomer Marine Conservation Zone is an underwater marine nature reserve located off the coast of Pembrokeshire in Wales.

Skomer Volcanic Group
The Skomer Volcanic Group is a Silurian lithostratigraphic group (a sequence of rock strata) in Pembrokeshire, Wales. The name is derived from the island of Skomer off the west coast of Pembrokeshire. It was traditionally known as the Skomer Volcanic Series. The rocks are exposed across the island of Skomer and along the northern half of the nearby Marloes peninsula as far east as St Ishmaels. Lithology and stratigraphy The Group comprises around 1000m thickness of lava flows and associated strata including felsite, albite-trachyte Trachyte () is an extrusive igneous rock composed mostly of alkali feldspar. It is usually light-colored and aphanitic (fine-grained), with minor amounts of mafic minerals, and is formed by the rapid cooling of lava enriched with silica and al ..., keratophyre etc laid down during the Silurian Period.https://webapps.bgs.ac.uk/Lexicon/lexicon.cfm?pub=SVG (BGS on-line lexicon of rock units) References {{Reflist Silurian System Geology of ...

Sea Beet
The sea beet, ''Beta vulgaris'' subsp. ''maritima'' ((L.) Arcangeli.), is a member of the family Amaranthaceae, previously of the Chenopodiaceae. Carl Linnaeus first described ''Beta vulgaris'' in 1753; in the second edition of '' Species Plantarum'' in 1762, he divided the species into wild and cultivated varieties, giving the name ''Beta maritima'' to the wild taxon. The sea beet is native to the coasts of Europe, northern Africa, and southern Asia. The sea beet is the wild ancestor of common vegetables such as beetroot, sugar beet, and Swiss chard. Its leaves have a pleasant texture and taste, being good served raw or cooked, and because of this, it is also known as wild spinach. It is a large perennial plant which grows up to , and flowers in the summer. Its flowers are hermaphroditic, and wind-pollinated. It requires moist, well-drained soils, and does not tolerate shade. However, it is able to tolerate relatively high levels of sodium in its environment. Description Sea be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Fescue
''Festuca rubra'' is a species of grass known by the common name red fescue or creeping red fescue. It is widespread across much of the Northern Hemisphere and can tolerate many habitats and climates. It is best adapted to well-drained soils in cool, temperate climates; it prefers shadier areas and is often planted for its shade tolerance. Wild animals browse it, but it has not been important for domestic forage due to low productivity and palatability. It is also an ornamental plant for gardens. Description ''Festuca rubra'' is perennial and has sub-species that have rhizomes and/or form bunchgrass tufts. It mainly exists in neutral and acidic soils. It can grow between 2 and 20 cm tall. Like all fescues, the leaves are narrow and needle like, making it less palatable to livestock. The swards that it forms are not as tufted as sheep's fescue (''Festuca ovina'') or wavy hair grass (''Deschampsia flexuosa''). The tufted nature is what gives the grass its springy characterist ...

Atlantic Puffin
The Atlantic puffin ('), also known as the common puffin, is a species of seabird in the auk family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin is found in the northeastern Pacific. The Atlantic puffin breeds in Russia, Iceland, Ireland, Norway, Greenland, Newfoundland and Labrador, Nova Scotia, and the Faroe Islands, and as far south as Maine in the west and France in the east. It is most commonly found in the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds on small fish and crabs, which it catches by diving underwater, using its wings for propulsion. This puffin has a black crown and back, pale grey cheek patches, and a white body and underparts. Its broad, bold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manx Shearwater
The Manx shearwater (''Puffinus puffinus'') is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century. Puffin is an Anglo-Norman word (Middle English ''pophyn'') for the cured carcasses of nestling shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits. Taxonomy The shearwaters form part of the family Procellariidae, a widespread group containing nearly 100 species of medium to large seabirds. They have long, narrow wings and the characteristic “tube nose”. Although it was considered a monotypic species, recently an endemic subspecies for the Canary Islands has been proposed ''P. puffinus canariensis''. The large genus ''Puffinus'' includes several species formerly considered to be subspecies of the Manx shearwater, including the yelkouan shearwater, Balearic shearwater, Hutton's shearwater ...

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely.

Aeronian
In the geologic timescale, the Aeronian is an age of the Llandovery Epoch of the Silurian Period of the Paleozoic Era of the Phanerozoic Eon that began 440.8 ± 1.2 Ma and ended 438.5 ± 1.1 Ma (million years ago). The Aeronian Age succeeds the Rhuddanian Age and precedes the Telychian Age, all in the same epoch. GSSP The GSSP is located in the Trefawr Track section, 500m north of Cwm-coed-Aeron Farm, Wales, UK. The GSSP lies within the gently-dipping blocky mudstones of the Trefawr Formation, which principally yield abundant and diverse shelly faunas, but also contain enough graptolites Graptolites are a group of colonial animals, members of the subclass Graptolithina within the class Pterobranchia.

Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 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 shortest period of the Paleozoic Era. 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) became fully terrestrialized.

Pembrokeshire
Pembrokeshire ( ; cy, Sir Benfro ) is a Local government in Wales#Principal areas, county in the South West Wales, south-west of Wales. It is bordered by Carmarthenshire to the east, Ceredigion to the northeast, and the rest by sea. The county is home to Pembrokeshire Coast National Park. The Park occupies more than a third of the area of the county and includes the Preseli Hills in the north as well as the Pembrokeshire Coast Path. Historically, mining and fishing were important activities, while industry nowadays is focused on agriculture (86 per cent of land use), oil and gas, and tourism; Pembrokeshire's beaches have won many awards. The county has a diverse geography with a wide range of geological features, habitats and wildlife. Its prehistory and modern history have been extensively studied, from tribal occupation, through Roman times, to Welsh, Irish, Norman, English, Scandinavian and Flemish influences.
