Waltham Abbey SSSI
Waltham Abbey SSSI is a biological Site of Special Scientific Interest which is located within the Waltham Abbey Royal Gunpowder Mills at Waltham Abbey in Essex. History For 300 years the area was cut off from its surroundings by river boundaries and the highly secret nature of its work. The site was finally closed in 1991. Decontamination work was carried out between 1992-96 and the site opened to the public in 2001. Location The woodland site lies to the north of the present day Gunpowder Mills and is bounded by the River Lee Flood Relief Channel to the north and west while the Cornmill Stream forms its eastern boundary. Description The site is alder woodland on damp soils, with other trees including sycamore, ash and crack willow. The trees were planted around 1700 to provide charcoal for the manufacture of gunpowder, and planting ceased at the time of the First World War. The wood has the largest heronry in Essex, which was present in 1974 and had 26 pairs in 1984. Ot ... [...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/ASSIs may ...

Tawny Owl
The tawny owl (''Strix aluco''), also called the brown owl, is commonly found in woodlands across Europe to western Siberia, and has seven recognized subspecies. It is a stocky, medium-sized owl, whose underparts are pale with dark streaks, and whose upper body may be either brown or grey. (In several subspecies, individuals may be of either color.) The tawny owl typically makes its nest in a tree hole where it can protect its eggs and young against potential predators. It is non-migratory and highly territorial: as a result, when young birds grow up and leave the parental nest, if they cannot find a vacant territory to claim as their own, they will often starve. The tawny owl is a nocturnal bird of prey. It is able to hunt successfully at night because of its vision and hearing adaptations and its ability to fly silently. It usually hunts by dropping suddenly from a perch and seizing its prey, which it swallows whole. It hunts mainly rodents, although in urbanized areas its d ...

Nature Reserves In Essex
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant " birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word '' physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by ...

Waltham Cross Railway Station
Waltham Cross railway station is on the West Anglia Main Line, serving the suburban town of Waltham Cross in Hertfordshire, and the neighbouring Waltham Abbey in Essex, England. It is down the line from London Liverpool Street and is situated between and . Its three-letter station code is WLC and it is in Travelcard zone 7. The station and all trains serving it are operated by Greater Anglia. The station has 4 Oyster card readers rather than ticket barriers. During the 2012 Olympic Games, Waltham Cross and Cheshunt provided the main rail access to the Lee Valley White Water Centre. History Early years (1840-1862) The first station, together with the railway line from Stratford to Broxbourne, was opened by the Northern & Eastern Railway (N&ER) on 15 September 1840. Originally called Waltham and later renamed to Waltham Cross, it was originally on a site to the north of the road between Waltham Cross and Waltham Abbey. Following on from negotiations in 1843, the Eastern Count ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackcap
The Eurasian blackcap (''Sylvia atricapilla''), usually known simply as the blackcap, is a common and widespread typical warbler. It has mainly olive-grey upperparts and pale grey underparts, and differences between the five subspecies are small. Both sexes have a neat coloured cap to the head, black in the male and reddish-brown in the female. The male's typical song is a rich musical warbling, often ending in a loud high-pitched crescendo, but a simpler song is given in some isolated areas, such as valleys in the Alps. The blackcap's closest relative is the garden warbler, which looks quite different but has a similar song. The blackcap breeds in much of Europe, western Asia and northwestern Africa, and its preferred habitat is mature deciduous woodland. The male holds a territory when breeding, which is defended against garden warblers as well as other blackcaps. The nest is a neat cup, built low in brambles or scrub, and the clutch is typically 4–6 mainly buff eggs, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedge Warbler
The sedge warbler (''Acrocephalus schoenobaenus'') is an Old World warbler in the genus '' Acrocephalus''. It is a medium-sized warbler with a brown, streaked back and wings and a distinct pale supercilium. Sedge warblers are migratory, crossing the Sahara to get from their European and Asian breeding grounds to spend winter in Africa. The male's song is composed of random chattering phrases and can include mimicry of other species. The sedge warbler is mostly insectivorous. Taxonomy The sedge warbler was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Motacilla schoenobaenus''. The species is now placed in the genus '' Acrocephalus'' that was introduced in 1811 by Johann Andreas Naumann and his son Johann Friedrich Naumann. British ornithologists did not distinguish the species from the Eurasian reed warbler until the 18th century. The genus name ''Acrocephalus'' is from Ancient Gree ...

Reed Warbler
The ''Acrocephalus'' warblers are small, insectivorous passerine birds belonging to the genus ''Acrocephalus''. Formerly in the paraphyletic Old World warbler assemblage, they are now separated as the namesake of the marsh and tree warbler family Acrocephalidae. They are sometimes called marsh warblers or reed warblers, but this invites confusion with marsh warbler and reed warbler proper, especially in North America, where it is common to use lower case for bird species. These are rather drab brownish warblers usually associated with marshes or other wetlands. Some are streaked, others plain. Many species breeding in temperate regions are migratory. This genus has heavily diversified into many species throughout islands across the tropical Pacific. This in turn has led to many of the resulting insular endemic species to become endangered. Several of these species (including all but one of the species endemic to the Marianas and two endemic to French Polynesia) have already gon ...

Tree Sparrow
The Eurasian tree sparrow (''Passer montanus'') is a passerine bird in the sparrow family with a rich chestnut crown and nape, and a black patch on each pure white cheek. The sexes are similarly plumaged, and young birds are a duller version of the adult. This sparrow breeds over most of temperate Eurasia and Southeast Asia, where it is known as the tree sparrow, and it has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native unrelated American tree sparrow. Although several subspecies are recognised, the appearance of this bird varies little across its extensive range. The Eurasian tree sparrow's untidy nest is built in a natural cavity, a hole in a building or the disused nest of a European magpie or white stork. The typical clutch is five or six eggs which hatch in under two weeks. This sparrow feeds mainly on seeds, but invertebrates are also consumed, particularly during ...

Heronry
A heronry, sometimes called a heron rookery, is a breeding ground for herons. Notable heronries Although their breeding territories are often on more protected small islands in lakes or retention ponds, herons breed in heronries (or also called rookeries, especially since other birds join them like spoonbills, storks, and cormorants). Some of the notable heronries are: Asia * Kaggaladu Heronry is in Karnataka state of India. This heronry, in the Tumkur district of Karnataka, was first made known to the outside world in 1999 by members of the Tumkur-based NGO Wildlife Aware Nature Club. Europe * |
Waltham Abbey Royal Gunpowder Mills
The Royal Gunpowder Mills are a former industrial site in Waltham Abbey, England. It was one of three Royal Gunpowder Mills in the United Kingdom (the others being at Ballincollig and Faversham). Waltham Abbey is the only site to have survived virtually intact. The Royal Gunpowder Mills, Waltham Abbey, were in operation for over 300 years. Starting in the mid-1850s the site became involved in the development of revolutionary nitro-based explosives and propellants known as "smokeless powder". The site grew in size, and black powder became less important. Shortly after the Second World War it became solely a Defence Research Establishment – firstly the Explosives Research and Development Establishment, then the Propellants, Explosives and Rocket Motor Establishment Waltham Abbey; and finally the Royal Armament Research and Development Establishment Waltham Abbey. The Mills are an ''Anchor Point'' of the European Route of Industrial Heritage, set in of parkland and contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
