Sleightholme Beck Gorge – The Troughs
Sleightholme Beck Gorge – The Troughs is a Site of Special Scientific Interest in the County Durham (district), County Durham district of south-west County Durham, England. The site covers a gorge in the valley of Sleightholme Beck between the hamlet of Sleightholme and the confluence with the River Greta, Durham, River Greta, some 3 km upriver from the village of Bowes. The site has both biological and geological interest and has been designated of national importance in the Geological Conservation Review. The gorge is incised through the Namurian Great Limestone and is of particular interest because beds of sandstone in the middle of the section show structures characteristic of a shoreline, with the features of a river delta and barrier bar. The shallow soils that have developed on ledges and crevices in the limestone and on the scree slopes support a vegetation in which ferns such as maidenhair spleenwort, ''Asplenium trichomanes'', green spleenwort, ''Asplenium viri ...

Barnard Castle
Barnard Castle (, ) is a market town on the north bank of the River Tees, in County Durham, England. The town is named after and built around a medieval castle ruin. The town's Bowes Museum has an 18th-century Silver Swan automaton exhibit and paintings by Goya and El Greco. Barnard Castle is on the left bank of the River Tees, opposite to Startforth, and is south-west of the county town of Durham. Nearby towns include Bishop Auckland to the north-east, Darlington to the east and Richmond to the south-east. The largest employer is GlaxoSmithKline, with a manufacturing facility on the town's outskirts. History Before the Norman Conquest, in 1066, the upper half of Teesdale was combined into an Anglo-Norse estate, which was centred upon the ancient village of Gainford, and mortgaged to the Earls of Northumberland. During Norman times, in 1080, the first Norman Bishop of Durham, Bishop Walcher, was murdered. This led to the surrounding country being attacked and ...

Asplenium Viride
''Asplenium viride'' is a species of fern known as the green spleenwort because of its green stipes and rachides. This feature easily distinguishes it from the very similar-looking maidenhair spleenwort, ''Asplenium trichomanes''. Taxonomy Green spleenwort was described by Carl Linnaeus in his 1753 ''Species Plantarum'', under the name "''Asplenium Trich. ramosum''", with a type locality of "'" (rocks in Caernarfonshire). Under the rules of the International Code of Botanical Nomenclature, phrase names such as "''Asplenium Trichomanes ramosum''" are to be treated as orthographic errors – in this case, for "''Asplenium ramosum''". That name was later rejected in favour of William Hudson's later name ''Asplenium viride'', which had a type locality of "'" (damp rocks in the mountains of Wales, Yorkshire and Westmorland). A global phylogeny of ''Asplenium'' published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. ' ...

Brunton Bank Quarry
__NOTOC__ Brunton Bank Quarry is a disused quarry now designated as a Site of Special Scientific Interest (SSSI) in Northumberland, North East England. The quarry exposes a base layer of the Namurian Great Limestone stratigraphic unit, including the ''Chaetetes'' Band, the fossilised fauna within which is of current geological interest. Location and natural features Brunton Bank Quarry is situated in the south-west of the county of Northumberland, some south-west of Chollerford and north of Hexham. The site at High Brunton lies to the north of the B6318 road and Hadrian's Wall, which runs immediately south of the road; it is north of Turret 26A. The quarry's elevation is between and above sea level. Brunton Bank Quarry is one of a number of SSSIs which expose the Namurian Great Limestone; others include Sleightholme Beck Gorge – The Troughs and West Rigg Open Cutting, both to the south of this site, in County Durham. An ancient tumulus is noted within the boundary of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Rigg Open Cutting
West Rigg Open Cutting is a Site of Special Scientific Interest in the Wear Valley district of west County Durham, England. It is a disused ironstone quarry, located just over 1 km north of the village of Westgate, in Weardale. At West Rigg, the Slitt Vein, a 20 km-long quartz intrusion in the Namurian Great Limestone, is exposed at the surface; the exposure is up to 5 m wide over a distance of some 200 m. During Late Permian times, extensive mineralisation occurred in the vicinity of the Slitt Vein: high salinity fluids, rich in iron, permeated the Great Limestone which, throughout its full thickness, was mineralised, producing siderite and ankerite minerals which were subsequently oxidised, yielding a limonitic ore with an iron content of over 40 per cent. At West Rigg, the iron mineralisation extends up to 60 m on each side of the vein. The Slitt Vein is predominantly composed of quartz, with smaller amounts of fluorite and uneconomic amounts of ...

Common Sandpiper
The common sandpiper (''Actitis hypoleucos'') is a small Palearctic wader. This bird and its Americas, American sister species, the spotted sandpiper (''A. macularia''), make up the genus ''Actitis''. They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and Hybrid (biology), hybridize. Hybridization has also been Hybridisation in shorebirds#Other hybrid scolopacids, reported between the common sandpiper and the green sandpiper, a Basal (phylogenetics), basal species of the closely related genus ''Tringa''. Taxonomy The common sandpiper was Species description, formally described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Tringa hypoleucos''. The species is now placed together with the spotted sandpiper in the genus ''Actitis'' that was introduced in 1811 by the German ...

White-throated Dipper
The white-throated dipper (''Cinclus cinclus''), also known as the European dipper or just dipper, is an aquatic passerine bird found in Europe, Middle East, Central Asia and the Indian Subcontinent. The species is divided into several subspecies, based primarily on colour differences, particularly of the pectoral band. Taxonomy and systematics The white-throated dipper was described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Sturnus cinclus''. The current genus '' Cinclus'' was introduced by the German naturalist Moritz Balthasar Borkhausen in 1797. The name ''cinclus'' is from the Ancient Greek word that was used to describe small tail-wagging birds that resided near water. Of the five species now placed in the genus, a molecular genetic study has shown that the white-throated dipper is most closely related to the other Eurasian species, the brown dipper (''Cinclus pallasii''). There are 14 subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxus Baccata
''Taxus baccata'' is a species of evergreen tree in the family (botany), family Taxaceae, native to Western Europe, Central Europe and Southern Europe, as well as Northwest Africa, and parts of Southwest Asia.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . It is the tree originally known as yew, though with other related trees becoming known, it may be referred to as common yew, European yew, or in North America English yew. It is a woodland tree in its native range, and is also grown as an ornamental tree, hedge or topiary. The plant is poisonous, with toxins that can be absorbed through inhalation, ingestion, and transpiration through the skin. Consuming any part of the tree, excluding the aril, can be deadly and the consumption of even a small amount of the foliage can result in death. Taxonomy and naming The word ''yew'' is from Old English ''īw, ēow'', ultimately from Proto-Indo-European ''*h₁eyHw-''. Possibly entered Proto-Germanic language, Germanic la ...

''Geranium lucidum'', commonly known as shining cranesbill or (in North America) shining geranium or shiny geranium, is a herbaceous annual plant of the genus ''Geranium''. It is native to Europe, western Asia and North Africa.
