Amwell Quarry
Amwell Quarry or Amwell Nature Reserve is a 37 hectare biological Site of Special Scientific Interest in Great Amwell in Hertfordshire. The planning authority is East Hertfordshire District Council. It is also part of the Lee Valley Ramsar Site and Special Protection Area, and is owned and managed by the Hertfordshire and Middlesex Wildlife Trust. The site is a former gravel pit, which has been restored to become a wetland nature reserve with two lakes, Great Hardmead Lake and Hollycross Lake. It is internationally important for wintering wildfowl, and is Britain's most important site for dragonflies. It also has large communities of damselflies and breeding birds. Plants include marsh dock and hairlike pondweed, both nationally rare. Amwell has a quarter of all British species of molluscs. There is access from Amwell Lane and the site is open at all times.

Hertfordshire
Hertfordshire ( or ; often abbreviated Herts) is one of the home counties in southern England. It borders Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it forms part of the East of England region. Hertfordshire covers . It derives its name – via the name of the county town of Hertford – from a hart (stag) and a ford, as represented on the county's coat of arms and on the flag. Hertfordshire County Council is based in Hertford, once the main market town and the current county town. The largest settlement is Watford. Since 1903 Letchworth has served as the prototype garden city; Stevenage became the first town to expand under post-war Britain's New Towns Act of 1946. In 2013 Hertfordshire had a population of about 1,140,700, with Hemel Hempstead, Stevenage, Watford and St Albans (the county's only ''city'') each having between 50,000 and 100,000 r ...

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/ASSIs may ...

Great Amwell
Great Amwell is a village and civil parish in the East Hertfordshire district, in the county of Hertfordshire, England. It is southeast of Ware and about north of London. History On a hill above the church there are some traces of an Iron Age hill fort, but more substantial remains of the earthworks were destroyed by landscaping of the Old Vicarage gardens in about 1840. To the west, on the road to Hertford, is a large tumulus at Barrowfield. In the Domesday Book of 1086 Great Amwell and neighbouring Little Amwell were a single parish recorded as "Emmewell". By the 17th century, the name of the village was recorded as Amwell Magna, Much Amwell or Great Amwell. The name is probably derived from a spring to the northeast of the village called Emma's Well, which was used by Sir Hugh Myddelton as one of the sources of the New River in the early 17th century. It is believed to have been named after Queen Emma of Normandy, wife of King Cnut the Great. A nearby white stone memorial ...

East Hertfordshire District Council
East or Orient is one of the four cardinal directions or points of the compass. It is the opposite direction from west and is the direction from which the Sun rises on the Earth. Etymology As in other languages, the word is formed from the fact that east is the direction where the Sun rises: ''east'' comes from Middle English ''est'', from Old English ''ēast'', which itself comes from the Proto-Germanic *''aus-to-'' or *''austra-'' "east, toward the sunrise", from Proto-Indo-European *aus- "to shine," or "dawn", cognate with Old High German ''*ōstar'' "to the east", Latin ''aurora'' 'dawn', and Greek ''ēōs'' 'dawn, east'. Examples of the same formation in other languages include Latin oriens 'east, sunrise' from orior 'to rise, to originate', Greek ανατολή anatolé 'east' from ἀνατέλλω 'to rise' and Hebrew מִזְרָח mizraḥ 'east' from זָרַח zaraḥ 'to rise, to shine'.

Lee Valley
The Lea Valley, the valley of the River Lea, has been used as a transport corridor, a source of sand and gravel, an industrial area, a water supply for London, and a recreational area. The London 2012 Summer Olympics were based in Stratford, in the Lower Lea Valley. It is important for London's water supply, as the source of the water transported by the New River aqueduct, but also as the location for the Lee Valley Reservoir Chain, stretching from Enfield through Tottenham and Walthamstow. Geography Physical geography The catchment area of the River Lea is located in the central part of the London Basin, on that basin's northern flank. The main underlying geological formation of the upper part of the Lea catchment, north of Hoddesdon, is Cretaceous Chalk. The main underlying geological formation of the lower part of the Lea catchment, south of Hoddesdon, is Eocene London Clay. However, large areas of these formations are overlain by much more recent Quaternary forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Potamogeton Trichoides
''Potamogeton trichoides'' is a species of aquatic plant known by the common name hairlike pondweed, native to Europe and western Asia where it grows in calcareous, usually nutrient-rich standing or slow-flowing water. Description Hairlike pondweed is an aquatic perennial that dies back each winter into a large number of asexually produced resting bodies called Turion (botany), turions. There are no rhizomes. It produces slender, cylindrical or slightly compressed, branching stems usually less than a metre in length but occasionally up to 2 m. The submerged leaves are long and very narrow, typically 16–80 mm long and 0.3–1 mm wide, with the midrib occupying up to 70% of the width of the leaf near the base.
