Braeburn Park
Braeburn Park is a nature reserve in Crayford in the London Borough of Bexley. It is managed by the London Wildlife Trust, and includes Wansunt Pit, a geological Site of Special Scientific Interest. The area was once used for market gardening; there were orchards, and the Old Crayford Gun Club had been based here. Later, like much of the nearby Dartford Heath, the site was extensively quarried (notably for sand), until it was finally infilled and abandoned in the 1980s; after which time it gradually reverted to nature. Habitats now include ruderal scrub, grassland and woodland. There is a wide variety of invertebrates, including rare ones such as skipping flower beetles and picture-winged flies. There is also a pond, and many common bird species. Reptiles catalogued here include the grass snake, common lizard and slow-worm. There is access to the reserve from Lower Station Road and Galloway Drive, Crayford. A large housing development called Braeburn Park was built here ...

Crayford
Crayford is a town and electoral ward in South East London, England, within the London Borough of Bexley. It lies east of Bexleyheath and north west of Dartford. Crayford was in the historic county of Kent until 1965. The settlement developed by the river Cray, around a ford that is no longer used. History An Iron Age settlement existed in the vicinity of the present St Paulinus Church between the Julian and Claudian invasions of Britain, from roughly 30 BC to AD 40. Roman ruins have been discovered and Crayford is one of several places proposed as the site of Noviomagus, a place mentioned in the Antonine Itinerary as being on the Roman equivalent of the later Watling Street. Crayford is also plausible as the site of the bloody battle of Crecganford ("Creeksford") in 457 in which Hengist defeated Vortimer to become the supreme sovereign of Kent. The Anglo-Saxon Chronicle written around 400 years later describes how Hengist and Æsc defeated the "Bret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

London Wildlife Trust
London Wildlife Trust (LWT), founded in 1981, is a local nature conservation charity for Greater London. It is one of 46 members of the Royal Society of Wildlife Trusts (known as The Wildlife Trusts), each of which is a local nature conservation charity for its area. The Trust aims to protect London's wildlife and wild spaces, and it manages over 40 nature reserves in Greater London. One of its campaigns is to turn London's gardens into mini-nature reserves, and it provides education services for schools. Local groups work on reserves and organise walks. The Trust's oldest reserves include Sydenham Hill Wood, which was managed by Southwark Wildlife Group before 1982 and thus was already a Trust reserve at that date. The campaign to save Gunnersbury Triangle began that same year, succeeding in 1983 when a public inquiry ruled that the site could not be developed because of its value for nature.Frith, 2012 The small Centre for Wildlife Gardening in East Dulwich has won an award f ...

Wansunt Pit
Wansunt Pit is a geological Site of Special Scientific Interest in Dartford Heath between Crayford in the London Borough of Bexley and Dartford in Kent. It is also a Geological Conservation Review site. It is important geologically because it exposes the Dartford Heath Gravel, and the relationship of this exposure to the Swanscombe sequence and the Thames Terraces is a controversial issue in Thames Pleistocene studies. The site is part of Braeburn Park, a nature reserve managed by the London Wildlife Trust. Archaeology The site is also important archaeologically. Excavations going back over a hundred years have revealed stone tools of Homo Heidelbergensis, dating from Marine Isotopic Stage 11, equivalent to the geological Hoxnian Stage, an interglacial period between 424,000 and 374,000 years ago. Other finds include sixteen Bronze Age axes and seventeen Iron Age gold armlets. The site The site is divided into two units. The first is crossed by Galloway Drive and the se ...

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 ...

Dartford Heath
Dartford Heath Common is an area of open heathland situated to the south-west of Dartford, Kent, England, covering around of open space. Dartford Heath is classified as lowland heath and is one of only two substantial heathland blocks remaining in Kent. The heath supports a number of rare plants and invertebrates, as well as reptiles, including the common lizard and slow-worm, and rabbits. History Prehistoric barrows, and Stone Age and Bronze Age artefacts have been discovered on Dartford Heath in some abundance. The heath has been important to local people since medieval times as common land; it therefore escaped enclosure during the late 18th and early 19th centuries, however during this period the heath was owned by the Tredegars and it was heavily excavated for granite, chalk and other natural resources. Many pits and holes were observed in the 1830s, some " 5 or 20fathoms deep. At the mouth and thence downward they were narrow, like the tunnel of a chimney or the passage ...

Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand, for example, aragonite, which has mostly been created, over the past 500million years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean. Somewhat more rarely, sand may be composed of calciu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landfill
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake. Once full, the area over a landfill site may be reclaimed for other uses. Operations Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to: # confine waste to as small an area as ...

Ruderal Species
A ruderal species is a plant species that is first to colonize disturbed lands. The disturbance may be natural for example, wildfires or avalanchesor the consequences of human activities, such as construction ( of roads, of buildings, mining, etc.) or agriculture (abandoned fields, irrigation, etc.). The term '' ruderal'' originates from the Latin word '' rudus'', meaning " rubble". Ruderal species typically dominate the disturbed area for a few years, gradually losing the competition to other native species. However, in extreme disturbance circumstances, such as when the natural topsoil is covered with a foreign substance, a single-species ruderal community may become permanently established. In addition, some ruderal invasive species may have such a competitive advantage over the native species that they, too, may permanently prevent a disturbed area from returning to its original state despite natural topsoil. Features Features contributing to a species' success as rudera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Picture-winged Fly
The Ulidiidae (formerly Otitidae) or picture-winged flies are a large and diverse cosmopolitan family of flies (Diptera), and as in related families, most species are herbivorous or detritivorous. They are often known as picture-winged flies, along with members of other families in the superfamily Tephritoidea that have patterns of bands or spots on the wings. Some species share with the Tephritidae an unusual elongated posteroapical projection of the anal cell in the wing, but can be differentiated by the smoothly curving subcostal vein. Two species, ''Tetanops myopaeformis'' and ''Euxesta stigmatias'', are agricultural pests. Systematics The Ulidiidae are divided into two subfamilies.

Grass Snake
The grass snake (''Natrix natrix''), sometimes called the ringed snake or water snake, is a Eurasian non-venomous colubrid snake. It is often found near water and feeds almost exclusively on amphibians. Subspecies Many subspecies are recognized, including: ''Natrix natrix helvetica'' ( Lacépède, 1789) was formerly treated as a subspecies, but following genetic analysis it was recognised in August 2017 as a separate species, ''Natrix helvetica'', the barred grass snake. Four other subspecies were transferred from ''N. natrix'' to ''N. helvetica'', becoming ''N. helvetica cettii'', ''N. helvetica corsa'', ''N. helvetica lanzai'' and ''N. helvetica sicula''. Description The grass snake is typically dark green or brown in colour with a characteristic yellow or whitish collar behind the head, which explains the alternative name ringed snake. The colour may also range from grey to black, with darker colours being more prevalent in colder regions, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
