Roswell Pits
Roswell Pits is an 8 hectare nature reserve on the eastern outskirts of Ely in Cambridgeshire. It is managed by the Environment Agency. It is part of the Ely Pits and Meadows Site of Special Scientific Interest (SSSI)) and Geological Conservation Review site. The SSSI designation for both biological and geological interest. The site was formerly managed by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire. History The pits were a source of gault, an impervious clay used to maintain river banks in the low-lying regions of the South Level of the Fens. Following the re-routing of the rivers in the region by Cornelius Vermuyden and his Adventurers in the 1650s, to more effectively drain the Fens, the peaty soils began to dry out and shrink.''The Urgent Hour'', (1983), John Beckett, Ely Local History Publication Board, As the land surface sunk below the levels of the rivers, it became important to maintain the banks with something impervious to water, to preven ...

Ely, Cambridgeshire
Ely ( ) is a cathedral city in the East Cambridgeshire district of Cambridgeshire, England, about north-northeast of Cambridge and from London. Ely is built on a Kimmeridge Clay island which, at , is the highest land in the Fens. It was due to this topography that Ely was not waterlogged like the surrounding Fenland, and was an island separated from the mainland. Major rivers including the River Witham, Witham, River Welland, Welland, River Nene, Nene and River Great Ouse, Great Ouse feed into the Fens and, until draining commenced in the eighteenth century, formed freshwater marshes and Mere (lake), meres within which peat was laid down. Once the Fens were drained, this peat created a rich and fertile soil ideal for farming. The River Great Ouse was a significant means of transport until the Fens were drained and Ely ceased to be an island in the seventeenth century. The river is now a popular boating spot, and has a large marina. Although now surrounded by land, the city ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Great Ouse
The River Great Ouse () is a river in England, the longest of several British rivers called "Ouse". From Syresham in Northamptonshire, the Great Ouse flows through Buckinghamshire, Bedfordshire, Cambridgeshire and Norfolk to drain into the Wash and the North Sea near Kings Lynn. Authorities disagree both on the river's source and its length with one quoting and another . Mostly flowing north and east, it is the fifth longest river in the United Kingdom. The Great Ouse has been historically important for commercial navigation, and for draining the low-lying region through which it flows; its best-known tributary is the Cam, which runs through Cambridge. Its lower course passes through drained wetlands and fens and has been extensively modified, or channelised, to relieve flooding and provide a better route for barge traffic. The unmodified river would have changed course regularly after floods. The name ''Ouse'' is from the Celtic or pre-Celtic *''Udso-s'', and probably me ...

Anax Imperator
The emperor dragonfly or blue emperor (''Anax imperator'') is a large species of hawker dragonfly of the family Aeshnidae, averaging in length. The generic name ''Anax'' is from the ancient Greek , "lord"; the specific epithet ''imperator'' is the Latin for "emperor", from ''imperare'', to command. Distribution This dragonfly has a wide distribution; it is found throughout Africa and through most of Europe, the Arabian Peninsula, and south-western and central Asia. Since 2000, its range has expanded in Europe, both northwards and to higher altitudes. Behaviour They frequently fly high up into the sky in search of prey, which includes butterflies, other Odonata and tadpoles; small prey is eaten while flying. They breed in a variety of aquatic habitats from large ponds to dikes, but they require a plentiful supply of vegetation in the water. The females lay the eggs into plants such as pondweed, and always lay alone. The larvae are very aggressive and are likely to influence the ...

Ophrys Apifera
''Ophrys apifera'', known in Europe as the bee orchid, is a perennial herbaceous plant of the family Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, as well as of a highly selective and highly evolved plant–pollinator relationship. Description ''Ophrys apifera'' grows to a height of . This hardy orchid develops small rosettes of leaves in autumn that continue to grow slowly during winter. Basal leaves are ovate or oblong-lanceolate, and upper leaves and bracts are ovate-lanceolate and sheathing. Leaves exhibit parallel venation. The plant blooms from mid-April in continental Europe, but in the United Kingdom it flowers June to July. A flower spike is produced, composed from one to twelve flowers. Three large, purple sepals surround the base of the flower, which can easily be mistaken for petals. The true petals lie just above the sepals as two short, pubescent green structures protruding laterally from a central column. A third, ...

Acrocephalus Scirpaceus
The common reed warbler (''Acrocephalus scirpaceus'') is an Old World warbler in the genus '' Acrocephalus''. It breeds across Europe into the temperate western Palaearctic where it is migratory, wintering in sub-Saharan Africa. It is also a resident species over large parts of Africa. Taxonomy The common reed warbler was formally described in 1804 by the French naturalist Johann Hermann under the binomial name ''Turdus scirpaceus''. The type locality is Alsace. The common reed warbler is now one of around 40 species placed in the genus '' Acrocephalus'' that was introduced by Johann Andreas Naumann and his son Johann Friedrich Naumann in 1811. The genus name ''Acrocephalus'' is from Ancient Greek ''akros'', "highest", and ''kephale'', "head". It is possible that the Naumanns thought ''akros'' meant "sharp-pointed". The specific ''scirpaceus'' is from Latin and means "reed". Ten subspecies are recognised: * ''A. s. scirpaceus'' (Hermann, 1804) – breeds in Europe to west Russ ...

Alcedo Atthis
The common kingfisher (''Alcedo atthis''), also known as the Eurasian kingfisher and river kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter. This sparrow-sized bird has the typical short-tailed, large-headed kingfisher profile; it has blue upperparts, orange underparts and a long bill. It feeds mainly on fish, caught by diving, and has special visual adaptations to enable it to see prey under water. The glossy white eggs are laid in a nest at the end of a burrow in a riverbank. Taxonomy The common kingfisher was first described by Carl Linnaeus in the 10th edition of his ''Systema Naturae'' in 1758 as ''Gracula atthis''. The modern binomial name derives from the Latin ', 'kingfisher' (from Greek , '), and ''Atthis'', a beautiful young woman of Lesbos, and favourite of Sappho. The genus ''Alcedo'' comprises s ...

Sterna Hirundo
The common tern (''Sterna hirundo'') is a seabird in the family Laridae. This bird has a circumpolar distribution, its four subspecies breeding in temperate and subarctic regions of Europe, Asia and North America. It is strongly migratory, wintering in coastal tropical and subtropical regions. Breeding adults have light grey upperparts, white to very light grey underparts, a black cap, orange-red legs, and a narrow pointed bill. Depending on the subspecies, the bill may be mostly red with a black tip or all black. There are several similar species, including the partly sympatric Arctic tern, which can be separated on plumage details, leg and bill colour, or vocalisations. Breeding in a wider range of habitats than any of its relatives, the common tern nests on any flat, poorly vegetated surface close to water, including beaches and islands, and it readily adapts to artificial substrates such as floating rafts. The nest may be a bare scrape in sand or gravel, but it is of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnt Fen
Burnt Fen is an area of low-lying land crossed by the A1101 road between Littleport in Cambridgeshire and Mildenhall in Suffolk, England. It is surrounded on three sides by rivers, and consists of prime agricultural land, with sparse settlement. It is dependent on pumped drainage to prevent it from flooding. Between 1759 and 1962 the area was managed by the Commissioners of the Burnt Fen First Drainage District, who were then replaced by the Burnt Fen Internal Drainage Board, when the area of responsibility was expanded. Funding for the drainage works is collected by a system of rates, paid by those whose property would be threatened by flooding without the works. Location Burnt Fen is located near the eastern borders of the Isle of Ely, Cambridgeshire, although parts of it are also located in Suffolk and Norfolk. It is an area of prime agricultural land, which is mostly below sea level, and all of it is below the normal flood levels of the rivers which surround it on three si ...

Cornelius Vermuyden
Sir Cornelius Vermuyden (Sint-Maartensdijk, 1595 – London, 11 October 1677) was a Dutch engineer who introduced Dutch land reclamation methods to England. Vermuyden was commissioned by the Crown to drain Hatfield Chase in the Isle of Axholme, Lincolnshire, Vermuyden was knighted in 1629 for his work and became an English citizen in 1633. In the 1650s, he directed major projects to drain The Fens of East Anglia, introducing the innovation of constructing washes, to allow periodic flooding of the area by excess waters. Early life and education Cornelius was the son of Giles Vermuyden and Sarah Werkendet. He was born in 1595 in Sint-Maartensdijk on the Isle of Tholen in Zeeland, Netherlands. He trained in the Netherlands as an engineer, learning Dutch techniques for controlling water and draining marshland. Career in England By the period of 1621 to 1623, Vermuyden was working in England, where his first projects were on the River Thames, repairing a sea wall at Dagenham and wo ...
