Afon Ysgir
is a river which rises on the southern slopes of Mynydd Epynt in Powys, Wales. The tributaries known as Ysgir Fawr and Ysgir Fechan flow past the hamlets of Pont Rhyd-y-berry and Merthyr Cynog to combine at Pont-faen and continue past the village of Battle to join the River Usk at Aberyscir. Its upper reaches are within the military training area of SENTA, the British Army's Sennybridge Training Area. Near its mouth is a Motte-and-bailey, motte, the historic church at Aberyscir and east of the river, the Roman fort of CICVCIVM or Y Gaer, Brecon, Brecon Gaer. Along with other tributaries of the Usk, the river is designated as a special area of conservation or 'SAC' for various species of fish including lamprey, the twaite shad and the European bullhead.http://www.ccw.gov.uk Countryside Council for Wales website References {{DEFAULTSORT:Ysgir Epynt, Afon Ysgir Rivers of the Brecon Beacons National Park Rivers of Powys ...

River
A river is a natural stream of fresh water that flows on land or inside Subterranean river, caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the Runoff (hydrology), runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their Bank (geography), banks and flood the surrounding area, spreading nutrients to the surrounding area.

Motte-and-bailey
A motte-and-bailey castle is a European fortification with a wooden or stone keep situated on a raised area of ground called a motte, accompanied by a walled courtyard, or bailey, surrounded by a protective ditch and palisade. Relatively easy to build with unskilled labour, but still militarily formidable, these castles were built across northern Europe from the 10th century onwards, spreading from Normandy and Anjou in France, into the Holy Roman Empire, as well as the Low Countries it controlled, in the 11th century, when these castles were popularized in the area that became the Netherlands. The Normans introduced the design into England and Wales. Motte-and-bailey castles were adopted in Scotland, Ireland, and Denmark in the 12th and 13th centuries. By the end of the 13th century, the design was largely superseded by alternative forms of fortification, but the earthworks remain a prominent feature in many countries.

Epynt
Mynydd Epynt () is an upland region of Mid Wales, within the county of Powys. It is bounded on the south by the upper stretch of the Usk Valley, on the north by the Irfon Valley, and on the east by the Wye Valley. Its western boundary is less distinct but lies east of the A483 Llandovery to Llanwrtyd Wells road. The area is an extensive plateau lying between 400 and 450m, drained by several southward-flowing rivers that empty into the River Usk; these include (from west to east) the Cilieni, the Nant Bran, the Afon Ysgir (with its two headwaters, the Ysgir Fechan and Ysgir Fawr) and the Afon Honddu. The Duhonw drains north-eastward into the River Wye. The highest point is a marilyn (having topographic prominence of at least 150m) of 478m. Since 1940, Mynydd Epynt has formed part of the Sennybridge Training Area, the largest military training zone in Wales.

European Bullhead
The European bullhead (''Cottus gobio'') is a freshwater fish that is widely distributed in Europe, mainly in rivers. It is a member of the family Cottidae, a type of sculpin. It is also known as the miller's thumb, freshwater sculpin, common bullhead, and cob. The European bullhead is a small demersal fish that lives both in cold, clear, fast-flowing small streams and in middle-sized rivers. It also occurs on gravelly shores of cold lakes. Further, it thrives in diluted brackish water of the Northern Baltic Sea. Description The bullhead has a large broad head and tapering body, large fins and a rounded tail. The eyes are located near the top of the head. To the distinction from the other freshwater sculpin species found in Northern Europe, it can be told from the alpine bullhead ''Cottus poecilopus'' by the fact that the rays of its pelvic fins are of similar lengths while the first and last rays are longer in the alpine bullhead. It can be distinguished from the fourhorn sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twaite Shad
The twait shad or twaite shad (''Alosa fallax'') is a species of fish in the family Alosidae. It is found in the eastern Atlantic Ocean and the Mediterranean Sea and is an anadromous fish which lives in the sea but migrates into fresh water to spawn. In appearance it resembles an Atlantic herring but has a row of six to ten distinctive spots on its silvery flanks. They become mature when three or more years old and migrate to estuaries, later swimming up rivers to spawn. Populations of this fish have declined due to overfishing, pollution and habitat destruction. Conservation of this species is covered by Appendix III of the Bern Convention and Appendix II and V of the European Community Habitats Directive. Description The twait shad is a typical herring-type fish and much resembles the allis shad. It has no lateral line and the belly is more rounded than that of the sprat and Baltic herring. The gill cover is ridged and the caudal peduncle has large, plate-like scales. This f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamprey
Lampreys (sometimes inaccurately called lamprey eels) are a group of Agnatha, jawless fish comprising the order (biology), order Petromyzontiformes , sole order in the Class (biology), class Petromyzontida. The adult lamprey is characterized by a toothed, funnel-like sucking mouth. The common name "lamprey" is probably derived from Latin , which may mean "stone licker" ( "to lick" + "stone"), though the etymology is uncertain. "Lamprey" is sometimes seen for the plural form. About 38 extant species of lampreys are known, with around seven known extinct species. They are classified in three families—two small families in the Southern Hemisphere (Geotriidae, Mordaciidae) and one large family in the Northern Hemisphere (Petromyzontidae). Genetic evidence suggests that lampreys are more closely related to hagfish, the only other living group of jawless fish, than they are to jawed vertebrates, forming the superclass Cyclostomi. The oldest fossils of stem-group lampreys are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Site of Community Importance, 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 Area of Special Conservation Interest, Areas of Special Conservation Interest (ASCIs) under the Convention on the conservation of European wildlife and natural habitats, Berne Convention.

Y Gaer, Brecon
Y Gaer () is a Roman fort situated near modern-day Brecon in Mid Wales, United Kingdom. Y Gaer is located at (Landranger 160). History Y Gaer was built around AD 75 and sits on a crossroads of Roman roads in the valley of the River Usk at a strategic point in Wales in the Roman Era, Roman Wales, linking South Wales and Mid Wales. It was part of a chain of similar forts, such as Gobannium at Abergavenny, a day's march away down the Usk valley, and larger bases, such as Moridunum (Carmarthen), Moridunum (Carmarthen) via Alabum (Llandovery), Cardiff Roman Fort to the south and Isca Augusta, Caerleon, the main base for the Roman legion locally. The site was excavated in the 1920s by Sir Mortimer Wheeler, a prominent archaeologist of his day. The fort was built for a contingent of up to 500 cavalrymen, recruited originally in Spain from the Vettones, and these Vettonian cavalry would have played a significant part in the conquest of the area held by the Silures.

Roman Fort
''Castra'' () is a Latin term used during the Roman Republic and Roman Empire for a military 'camp', and ''castrum'' () for a 'fort'. Either could refer to a building or plot of land, used as a fortified military base.. Included is a discussion about the typologies of Roman fortifications. In English usage, ''castrum'' commonly translates to "Roman fort", "Roman camp" and "Roman fortress". Scholastic convention tends to translate ''castrum'' as "fort", "camp", "marching camp" or "fortress". Romans used the term ''castrum'' for different sizes of camps – including large legionary fortresses, smaller forts for cohorts or for auxiliary forces, temporary encampments, and "marching" forts. The diminutive form ''castellum'' was used for fortlets, typically occupied by a detachment of a cohort or a ''centuria''. Etymology ''Castrum'' appears in Oscan and Umbrian, two other Italic languages, suggesting an origin at least as old as Proto-Italic language. Julius Pokorny traces ...

Sennybridge
Sennybridge () is a village in Powys, Wales, in the historic county of Brecknockshire, situated some from Cardiff and from Swansea. It lies west of Brecon on the A40 trunk road to Llandovery, at the point where the Afon Senni flows into the Usk. It is in the community of Maescar. Economy One factor that influenced the growth of Sennybridge was the Neath and Brecon Railway, which opened a station in the adjoining village of Defynnog in 1867. The promoter and contractor of the railway, John Dickson, also made a start on constructing a railway north from Sennybridge that would have linked the Neath and Brecon Railway to the Central Wales Line at Llangammarch Wells but work was suspended on his bankruptcy in 1867 and never resumed. The partially completed earthworks can still be seen in the countryside north of Sennybridge. In an earlier era, in about 1821 the Brecon Forest Tramroad started construction. The northern terminus of the route from the Swansea Valley (vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
