River Lynher
The River Lynher ( kw, Linar) (or St Germans River downstream from its confluence with the Tiddy) flows through east Cornwall, England, and enters the River Tamar at the Hamoaze, which in turn flows into Plymouth Sound. Navigation The normal tidal limit is a weir upstream of Notter Bridge. St Germans is a historic fishing village situated on the River Tiddy just upstream of its confluence with the Lynher. The Quay Sailing Club are based at St Germans Quay. The Queen's Harbour Master for Plymouth is responsible for managing navigation on the tidal Lynher and its tributaries (up to the normal tidal limits). Geography The river is about 21 miles (34 km long), rising at a height of about 920 feet (280m) on Bodmin Moor and flowing into the Tamar Estuary near Plymouth. It has four main tributaries, the largest of which is the River Tiddy. The smaller tributaries include Deans Brook, Withey Brook, Marke Valley and Darleyford streams and Kelly Brook.

Deans Brook
Deans Brook is a two-kilometre-long stream which runs between Mill Hill and Edgware in the London Borough of Barnet. It is a tributary of the Silk Stream, which is a tributary of the River Brent, which is a tributary of the River Thames. The brook rises on Mill Hill Golf Course, where it is dammed to form a large pond called Stoneywood Lake. It goes through a culvert under the M1 motorway to Stoneyfields Park, where it is again dammed to form an ornamental lake. It then passes through suburban Edgware, where it combines with the Edgware Brook to become the Silk Stream near Edgware Hospital. The stream largely follows its natural course, but most of the banks are restrained by wooden boards, and there is little aquatic vegetation. Kingfishers and grey wagtails are regularly seen along the brook. A tributary, Edgwarebury Brook, joins it behind Brook Avenue. The only part of the brook which is accessible to the public is in Stoneyfields Park. Deans Brook, Stoneyfields Park, allot ...

Black-tailed Godwit
The black-tailed godwit (''Limosa limosa'') is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. It is a member of the godwit genus, ''Limosa''. There are four subspecies, all with orange head, neck and chest in breeding plumage and dull grey-brown winter coloration, and distinctive black and white wingbar at all times. Its breeding range stretches from Iceland through Europe and areas of central Asia. Black-tailed godwits spend (the northern hemisphere) winter in areas as diverse as the Indian subcontinent, Australia, New Zealand, western Europe and west Africa. The species breeds in fens, lake edges, damp meadows, moorlands and bogs and uses estuaries, swamps and floods in (the northern hemisphere) winter; it is more likely to be found inland and on freshwater than the similar bar-tailed godwit. The world population is estimated to be 634,000 to 805,000 birds and is classified as Near Threatened. The black-tailed godwit is the national b ...

Pied Avocet
The pied avocet (''Recurvirostra avosetta'') is a large black and white wader in the avocet and stilt family, Recurvirostridae. They breed in temperate Europe and across the Palearctic to Central Asia then on to the Russian Far East. It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England. The pied avocet is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. Taxonomy The pied avocet was one of the many bird species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'', where it was given the binomial name of ''Recurvirostra avosetta''. This species gets its English and scientific names from the Venetian word ''avosetta''. It appeared first in Ulisse Aldrovandi's ''Ornithologia'' (1603).

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. The white-throated dipper is Norway's national bird. 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 ...

Eurasian Otter
The Eurasian otter (''Lutra lutra''), also known as the European otter, Eurasian river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia. The most widely distributed member of the otter subfamily (Lutrinae) of the weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others. Description The Eurasian otter is a typical species of the otter subfamily. Brown above and cream below, these long, slender creatures are well-equipped for their aquatic habits. Their bones show osteosclerosis, increasing their density to reduce buoyancy. This otter differs from the North American river otter by its shorter neck, broader visage, the greater space between the ears and its longer tail. However, the Eurasian otter is the only otter in much of its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Kingfisher
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 ...

Special Protection Area
A Special Protection Area (SPA) is a designation under the European Union Directive on the Conservation of Wild Birds. Under the Directive, Member States of the European Union (EU) have a duty to safeguard the habitats of migratory birds and certain particularly threatened birds. Together with Special Areas of Conservation (SACs), the SPAs form a network of protected sites across the EU, called Natura 2000. Each SPA has an EU code – for example the North Norfolk Coast SPA has the code ''UK9009031''. In the United Kingdom As at 21 September 2006, there were 252 classified SPAs and 12 proposed SPAs in England, Scotland, Wales and Northern Ireland. The Conservation (Natural Habitats etc.) Regulations 1994 implement the terms of the Directive in Scotland, England and Wales. In Great Britain, SPAs (and SACs) designated on land or in the intertidal area are normally also notified as Sites of Special Scientific Interest (SSSIs), and in Northern Ireland as Areas of Special Scientific ...

Natural England
Natural England is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. It is responsible for ensuring that England's natural environment, including its land, flora and fauna, freshwater and marine environments, geology and soils, are protected and improved. It also has a responsibility to help people enjoy, understand and access the natural environment. Natural England focuses its activities and resources on four strategic outcomes: * a healthy natural environment * enjoyment of the natural environment * sustainable use of the natural environment * a secure environmental future Roles and responsibilities As a non-departmental public body (NDPB), Natural England is independent of government. However, the Secretary of State for Environment, Food & Rural Affairs has the legal power to issue guidance to Natural England on various matters, a constraint that was not placed on its predecessor NDPBs. Its powers in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSI ...

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 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. Such individuals can grow to extremely large sizes, although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Trout
The brown trout (''Salmo trutta'') is a European species of salmonid fish that has been widely introduced into suitable environments globally. It includes purely freshwater populations, referred to as the riverine ecotype, ''Salmo trutta'' morpha ''fario'', a lacustrine ecotype, ''S. trutta'' morpha ''lacustris'', also called the lake trout, and anadromous forms known as the sea trout, ''S. trutta'' morpha ''trutta''. The latter migrates to the oceans for much of its life and returns to fresh water only to spawn. Sea trout in Ireland and Britain have many regional names: sewin in Wales, finnock in Scotland, peal in the West Country, mort in North West England, and white trout in Ireland. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. ''S. trutta'' morpha ''fario'' forms stream-resident populations, typically in alpine s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
