River Ythan
The Ythan is a river in the north-east of Scotland rising at Wells of Ythan near the village of Ythanwells and flowing south-eastwards through the towns of Fyvie, Methlick and Ellon, Aberdeenshire, Ellon before flowing into the North Sea near Newburgh, Aberdeenshire, Newburgh, in Formartine. The lower reach of the river is known as the Ythan Estuary, is a part of the River Ythan, Sands of Forvie and Meikle Loch Special Protection Area for conservation, particularly the breeding ground of three tern species (common tern, little tern and Sandwich tern) (Lumina, 2004). The River Ythan has a length of and a catchment area of . As figures of the discharge, are given or . Nitrate Vulnerable Zone The Scottish Government has designated the River Ythan catchment as a Nitrate vulnerable zone, Nitrate Vulnerable Zone following concerns about the spread of algal mats in the river during the 1990s. The resulting restrictions on the use of fertilisers in the catchment were criticised by m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellon, Aberdeenshire
Ellon () is a town in Aberdeenshire, Scotland, approximately north of Aberdeen, lying on the River Ythan, which has one of the few undeveloped river estuaries on the eastern coast of Scotland. It is in the ancient region of Formartine. Its name is believed to derive from the Gaelic term ''Eilean'', an island, on account of the presence of an island in the River Ythan, which offered a convenient fording point. In 1707 it was made a burgh of barony for the Earl of Buchan. It is home to a unique collection of ancient yew trees. Places of interest Places of interest within the town include Ellon Castle Gardens, recently brought back to life by volunteers and open to the public (see website for latest opening times). They include a walled garden of historical importance, yew trees dating back 500-800 years and the ruins of old Ellon Castle, and the surrounding walls known as the ''Deer Dyke''. Ellon also has ''Auld Brig'', a category A listed bridge across the Ythan, built in 17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Ythan 2024
A river is a natural stream of fresh water that flows on land or inside 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 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 banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Tern
The little tern (''Sternula albifrons'') is a seabird of the family Laridae. It was first described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name ''Sterna albifrons''. It was moved to the genus '' Sternula'' when the genus '' Sterna'' was restricted to the larger typical terns. The genus name ''Sternula'' is a diminutive of ''Sterna'', 'tern', while the specific name ''albifrons'' is from Latin ''albus'', 'white', and ''frons'', 'forehead'. Distribution This bird breeds on the coasts and inland waterways of temperate and tropical Europe, Asia, north and west Africa, and eastern Australia. It is strongly migratory, wintering in the subtropical and tropical oceans as far south as South Africa and Australia. Subspecies There are four subspecies. * The nominate ''S. a. albifrons'' occurs in Europe to North Africa and western Asia * ''S. a. guineae'' of western Africa * ''S. a. sinensis'' in eastern Asia (SE Russia to Japan, SE Asia, Philippines) ...

Ythan Wells
Ythan Wells, also known as Glenmailen, is the site of a Castra, Roman military camp, near the farm of Glenmellan, east of the village of Ythanwells in Aberdeenshire, Scotland. The site is a designated scheduled monument. Traces of two marching camps have been found at the site. The larger camp, covering some was discovered in 1785 by Col. Alex Shand. A smaller camp, extending to and partially overlapping the area of the first, was discovered by J. K. St Joseph in 1968. This smaller camp predates the larger and has been dated to the campaigns of Gnaeus Julius Agricola, Agricola. The site is situated at the headwaters of the River Ythan, where a series of natural spring (hydrology), springs supplies potable water, that was convenient for the large marching camp installed here by the Romans in the first few centuries AD. The Roman legions established a chain of very large forts at Ardoch Roman Fort, Ardoch, Strageath, Inchtuthil, Battledykes, Stracathro and R ...

Sea Trout
Sea trout is the common name usually applied to anadromous (sea-run) forms of brown trout (''Salmo trutta''), and is often referred to as ''Salmo trutta'' morpha ''trutta''. Other names for anadromous brown trout are bull trout, sewin (Wales), peel or peal (southwest England), mort (northwest England), finnock (Scotland), white trout (Ireland) and salmon trout (culinary). The term "sea trout" is also used to describe other anadromous salmonids, such as coho salmon (''Oncorhynchus kisutch''), coastal cutthroat trout (''Oncorhynchus clarkii clarkii''), brook trout (''Salvelinus fontinalis''), Arctic char (''Salvelinus alpinus alpinus'') and Dolly Varden (''Salvenlinus malma''). Even some non-salmonid fish species are also commonly known as sea trout, such as Northern pikeminnow (''Ptychocheilus oregonensis'') and members of the weakfish family (''Cynoscion''). Range Anadromous brown trout are widely distributed in Europe along the Atlantic and Baltic coasts, the United Kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Salmon
The Atlantic salmon (''Salmo salar'') is a species of ray-finned fish in the family Salmonidae. It is the third largest of the Salmonidae, behind Hucho taimen, Siberian taimen and Pacific Chinook salmon, growing up to a meter in length. Atlantic salmon are found in the northern Atlantic Ocean and in rivers that flow into it. Most populations are anadromous, hatching in streams and rivers but moving out to sea as they grow where they mature, after which the adults seasonally move upstream again to spawn. When the mature fish re-enter rivers to spawn, they change in colour and appearance. Some populations of this fish only migrate to large lakes, and are "landlocked", spending their entire lives in freshwater. Such populations are found throughout the range of the species. Unlike Pacific species of salmon, ''S. salar'' is iteroparous, which means it can survive spawning and return to sea to repeat the process again in another year with 5–10% returning to the sea to spawn again ...

River Ithon
The River Ithon ( Welsh: Afon Ieithon) is a major left-bank tributary of the River Wye in Powys, mid Wales. It rises in the broad saddle between the western end of Kerry Hill and the hill of Glog to its west and flows initially southwards to Llanbadarn Fynydd. It then takes a twisting route south via the villages of Llanbister, Llanddewi Ystradenny and Penybont before turning southwest, then doubling back northwards towards Crossgates. From here it resumes a southwesterly course, flowing past Llandrindod Wells and the site of Cefnllys Castle to a confluence with the Wye, 1 mile to the south of Newbridge-on-Wye.Ordnance Survey 1:25,000 scale Explorer map sheets 200 ''Llandrindod Wells & Elan Valley'' and 214 ''Llanidloes & Newtown'' Camddwr : ''For the tributary of the River Towy, see Camddwr and for the tributary of the River Teifi The River Teifi ( ; , ), formerly anglicised as Tivy, forms the boundary for most of its length between the Welsh counties of Ceredigion ...

Welsh Language
Welsh ( or ) is a Celtic languages, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales by about 18% of the population, by some in England, and in (the Welsh colony in Chubut Province, Argentina). It is spoken by smaller numbers of people in Canada and the United States descended from Welsh immigrants, within their households (especially in Nova Scotia). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Welsh and English are ''de jure'' official languages of the Senedd (the Welsh parliament), with Welsh being the only ''de jure'' official language in any part of the United Kingdom, with English being merely ''de facto'' official. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 538,300 ( ...

Old Welsh
Old Welsh () is the stage of the Welsh language from about 800 AD until the early 12th century when it developed into Middle Welsh.Koch, p. 1757. The preceding period, from the time Welsh became distinct from Common Brittonic around 550, has been called "Primitive"Koch, p. 1757. or "Archaic Welsh". Phonology The phonology of Old Welsh is as follows. * Older was diphthongized into in (stressed) final syllables, but it was retained elsewhere. Whilst this persisted as a diphthong in Middle Welsh, in Modern Welsh /aw/ has collapsed to following the stress shift to the penultimate, except in monosyllables. * and were allophones of and in unstressed non-final syllables. In Middle Welsh these merged to . * Old Welsh and became and in Modern Welsh final syllables, in dialects where /ɨ/ has not merged with /i/. Texts The oldest surviving text entirely in Old Welsh is understood to be that on a gravestone now in Tywyn – the Cadfan Stone – thought to date from the ...

Common Brittonic
Common Brittonic (; ; ), also known as British, Common Brythonic, or Proto-Brittonic, is a Celtic language historically spoken in Britain and Brittany from which evolved the later and modern Brittonic languages. It is a form of Insular Celtic, descended from Proto-Celtic, a theorized parent language that, by the first half of the first millennium BC, was diverging into separate dialects or languages. Pictish is linked, most probably as a sister language or a descendant branch. Evidence from early and modern Welsh shows that Common Brittonic was significantly influenced by Latin during the Roman period, especially in terms related to the church and Christianity. By the sixth century AD, the languages of the Celtic Britons were rapidly diverging into Neo-Brittonic: Welsh, Cumbric, Cornish, Breton, and possibly the Pictish language. Over the next three centuries, Brittonic was replaced by Scottish Gaelic in most of Scotland, and by Old English (from which descend M ...

Nitrate Vulnerable Zone
A nitrate vulnerable zone is a conservation designation of the Environment Agency for areas of land that drain into nitrate Polluted soil, polluted waters, or waterways that could become polluted by nitrates due to environmental and health threats. A nitrate vulnerable zone can be designated as a response to an increase in Leaching (agriculture), nitrate leaching or increased use of nitrate fertilizers. Nitrate pollution Sources of nitrate pollution One of the primary causes of nitrate pollution is the use of nitrogen fertilizers and application of manure to agricultural fields, which stimulates crop production but also contributes to nutrient pollution due to nitrate Leaching (agriculture), leaches from soil during heavy precipitation events. Environmental impacts Nitrate runoff can lead to eutrophication of waterways, leading to excessive algal growth and Hypoxia (environmental), oxygen depletion.
