Hill End Pit
Hill End Pit (also called Hill End Farm Pit or Hitch Wood Pit) is a nature reserve on the site of a former chalk pit, in St Paul's Walden in North Hertfordshire. It was formerly managed by the Herts and Middlesex Wildlife Trust (HMWT). In February 2016 HMWT announced that three sites, Barkway Chalk Pit, Hill End Pit and Pryor's Wood, which HMWT managed on behalf of their owner, North Hertfordshire District Council, were to return to Council management as the Trust was no longer able to meet the cost. It has the largest colony of Azeca goodalli snails in Hertfordshire. Plants include viper's bugloss, cowslip and marjoram, there are butterflies such as common blue and gatekeeper, and many birds including woodpeckers. The site is a Regionally important geological site (RIGS), dating to the Turonian age of the late Cretaceous around 90 million years ago, and was formerly a Site of Special Scientific Interest A Site of Special Scientific Interest (SSSI) in Great Britain ...

Hill End Pit 1
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film '' The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The '' Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher. Some definitions include a topographical prominence requirement, typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gatekeeper (butterfly)
The gatekeeper or hedge brown (''Pyronia tithonus'') is a European species of butterfly. Given its preference for warmer weather, the restriction of range expansion can be assumed to be due to climate. Colonies vary in size depending on the available habitat, and can range from a few dozen to several thousand butterflies. Similar species and subspecies It is a member of the subfamily Satyrinae in the family Nymphalidae. A similar species is the meadow brown; the two species can be difficult to distinguish with closed wings, since the underwing markings are very similar. However, the gatekeeper tends to rest with its wings open, whereas the meadow brown usually rests with its wings closed. The gatekeeper is also smaller and more orange than the meadow brown and has double pupils on its eyespots. Two other similar species of ''Pyronia'' are found in southern Europe, the southern gatekeeper ('' P. cecilia'') and the Spanish gatekeeper ('' P. bathsheba''). ''P. tithonu ...

Herts And Middlesex Wildlife Trust Reserves
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 resi ...

Department For Environment, Food And Rural Affairs
The Department for Environment, Food and Rural Affairs (Defra) is a department of His Majesty's Government responsible for environmental protection, food production and standards, agriculture, fisheries and rural communities in the United Kingdom. Concordats set out agreed frameworks for co operation, between it and the Scottish Government, Welsh Government and Northern Ireland Executive, which have devolved responsibilities for these matters in their respective nations. Defra also leads for the United Kingdom on agricultural, fisheries and environmental matters in international negotiations on sustainable development and climate change, although a new Department of Energy and Climate Change was created on 3 October 2008 to take over the last responsibility; later transferred to the Department for Business, Energy and Industrial Strategy following Theresa May's appointment as Prime Minister in July 2016.

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 inc ... [...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 ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Turonian
The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.8 Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage. At the beginning of the Turonian an oceanic anoxic event (OAE 2) took place, also referred to as the Cenomanian-Turonian boundary event or the "Bonarelli Event". Stratigraphic definition The Turonian (French: ''Turonien'') was defined by the French paleontologist Alcide d'Orbigny (1802–1857) in 1842. Orbigny named it after the French city of Tours in the region of Touraine (department Indre-et-Loire), which is the original type locality. The base of the Turonian Stage is defined as the place where the ammonite species '' Watinoceras devonense'' first appears in the stratigraphic column. The official reference profile (the GSSP) for the base of the Turonian is located in the Roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regionally Important Geological Site
Regionally important geological and geomorphological sites (RIGS) (also known as regionally important geological sites or, especially in Wales, regionally important geodiversity sites) are locally designated sites of local, national and regional importance for geodiversity (geology and geomorphology) in the United Kingdom and Isle of Man. RIGS may be designated for their value to Earth Science, and to Earth heritage in general, and may include cultural, educational, historical and aesthetic resources. The concept was introduced by the Nature Conservancy Council's publication ''Earth Science Conservation in Great Britain – A Strategy'' (1990). They are conserved and protected from development as a material consideration through the planning system by the Town and Country Planning Act 1990. They do not have the statutory management protection enjoyed by Sites of Special Scientific Interest (SSSIs) or Areas of Special Scientific Interest (Isle of Man). Local geological sites includ ...

Common Blue
The common blue butterfly or European common blue (''Polyommatus icarus'') is a butterfly in the family Lycaenidae and subfamily Polyommatinae. The butterfly is found throughout the Palearctic. Butterflies in the Polyommatinae are collectively called blues, from the coloring of the wings. Common blue males usually have wings that are blue above with a black-brown border and a white fringe. The females are usually brown above with a blue dusting and orange spots. Taxonomy and phylogeny This species was first described by Siegmund Adrian von Rottemburg in 1775. Vernacular names that have been given to ''P. icarus'' include little blew argus, blew argus, mixed argus, selvedg’d argus, ultramarine blue, caerulean butterfly, and alexis. Subspecies Subspecies include: * ''P. i. icarus'' (Europe, Caucasus, Transcaucasia) * ''P. i. mariscolore'' ( Kane, 1893) (Ireland) * ''P. i. fuchsi'' ( Sheljuzhko, 1928) (South Siberia, Transbaikalia) * ''P. i. omelkoi'' Dubatolov & Korshunov, 199 ...

Echium Vulgare
''Echium vulgare'', known as viper's bugloss and blueweed,Dickinson, T.; Metsger, D.; Bull, J.; & Dickinson, R. (2004) ROM Field Guide to Wildflowers of Ontario. Toronto:Royal Ontario Museum, p. 203. is a species of flowering plant in the borage family Boraginaceae. It is native to most of Europe and western and central Asia''Flora Europaea''''Echium vulgare''/ref> and it occurs as an introduced species in north-eastern North America, south-western South America and the South and North Island of New Zealand. The plant root was used in ancient times as a treatment for snake or viper bites. If eaten, the plant is toxic to horses and cattle through the accumulation of pyrrolizidine alkaloids in the liver. Description It is a biennial or monocarpic perennial plant growing to tall, with rough, hairy, oblanceolate leaves.
