Sound Heath
Sound Heath, also known as Sound Common, is an area of common land in Sound, Cheshire, Sound, near Nantwich in Cheshire, England, which includes Heath (habitat), heathland, grassland, shrubland, scrub, woodland and wetland habitats. The majority of the area is designated a Site of Special Scientific Interest and a Local Nature Reserve. One of the very few lowland heaths in Cheshire, Sound Heath is a valuable habitat for heathland plants and animals, although its heathland character is currently under threat from the spread of trees and scrub. The common's ponds form one of the most important sites in the county for freshwater invertebrates. Three nationally rare species, rare or endangered species, endangered species have been found within the area: the Omphiscola glabra, mud snail (which is now one of the UK's most endangered freshwater creatures, having been recently recategorised as near threatened across Europe in the new IUCN European Red List of Non-marine Molluscs), great ...

Sound Heath SSSI
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequency, frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an ''acoustician'', while someone working in the field of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Raft Spider
The great raft spider or fen raft spider (''Dolomedes plantarius'') is a European species of spider in the family Pisauridae. Like other ''Dolomedes'' spiders, it is semiaquatic, hunting its prey on the surface of water. It occurs mainly in neutral to alkaline, unpolluted water of fens and grazing marsh. Taxonomy The species was first described by arachnologist Carl Alexander Clerck in 1757 as ''Araneus plantarius''. Its genus was reclassified by Pierre André Latreille in 1804 to ''Dolomedes''. The species has also been described under the name ''Aranea viridata'' by Müller and as ''Dolomedes riparius'' by Hahn. The species is currently recognised as ''Dolomedes plantarius'' and has two widely recognised common names: the great raft spider and the fen raft spider. Morphology ''D. plantarius'' is a large species within its range. Adult females can have bodies of slightly over 20mm in length with a span of 70mm including their legs. It is typically black or brown in colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calluna Vulgaris
''Calluna vulgaris'', common heather, ling, or simply heather, is the sole species in the genus ''Calluna'' in the flowering plant family Ericaceae. It is a low-growing evergreen shrub growing to tall, or rarely to and taller, and is found widely in Europe and Asia Minor on acidic soils in open sunny situations and in moderate shade. It is the dominant plant in most heathland and moorland in Europe, and in some bog vegetation and acidic pine and oak woodland. It is tolerant of grazing and regenerates following occasional burning, and is often managed in nature reserves and grouse moors by sheep or cattle grazing, and also by light burning. ''Calluna'' was separated from the closely related genus ''Erica'' by Richard Anthony Salisbury, who devised the generic name ''Calluna'' probably from the Ancient Greek (), "beautify, sweep clean", in reference to its traditional use in besoms. The specific epithet ''vulgaris'' is Latin for 'common'. ''Calluna'' is differentiated from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Countryside And Rights Of Way Act 2000
The Countryside and Rights of Way Act 2000 (c. 37), known informally as the CRoW Act or "Right to Roam" Act is a United Kingdom Act of Parliament affecting England and Wales which came into force on 30 November 2000. Right to roam The Act implements the so-called "right to roam" (also known as ''jus spatiandi'') long sought by the Ramblers' Association and its predecessors, on certain upland and uncultivated areas of England and Wales. This element of the act was implemented in stages as conclusive maps of different regions were produced. The act refers to areas of 'mountain, moor, heath and down' in addition to registered common land; not all uncultivated land is covered. Rights of way A staged review of public rights of way, including limited rights to create new public footpaths where needed, is being conducted under the Act. Again, this is being conducted in a staged manner, which can produce anomalies – of the two administrative areas of the County of Gloucestershir ...

Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercia Mudstone Group
The Mercia Mudstone Group is an early Triassic lithostratigraphic group (a sequence of rock strata) which is widespread in Britain, especially in the English Midlands – the name is derived from the ancient kingdom of Mercia which corresponds to that area. It is frequently encountered in older literature as the Keuper Marl or Keuper Marl Series. The Mercia Mudstone Group is now divided into five formations recognised and mappable across its entire outcrop and subcrop. The formations are a mix of mudstones, siltstones, sandstones and halites. Historically this sequence of rocks has been subdivided in different ways with different names in each of the basinal areas in which it is found. Increasing knowledge of the sequences and the more recent development of seamless electronic mapping by the British Geological Survey (BGS) necessitated a reappraisal of these divisions. A report published by BGS in 2008 recommended the abandonment of previous divisions and naming schemes in favour o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keuper Marl
Keuper marl is a former and now deprecated term for multiple layers of mudstone and siltstone of Triassic age which occur beneath parts of the English Midlands and neighbouring areas e.g. Cheshire, Nottinghamshire, Devon, eastern Worcestershire and northern Yorkshire. Typically red, or occasionally green or grey, these strata are generally featureless and contain few fossils. In basin formations, thick halite-bearing layers, or rock salt deposits, are sometimes present at the base of the marl. In modern nomenclature, Keuper marl is included within the Mercia Mudstone Group The Mercia Mudstone Group is an early Triassic lithostratigraphic group (a sequence of rock strata) which is widespread in Britain, especially in the English Midlands – the name is derived from the ancient kingdom of Mercia which corresponds to t ....

Cheshire Plain
The Cheshire Plain is a relatively flat expanse of lowland within the county of Cheshire in North West England but extending south into Shropshire. It extends from the Mersey Valley in the north to the Shropshire Hills in the south, bounded by the hills of North Wales to the west and the foothills of the Pennines to the north-east. The Wirral Peninsula lies to the north-west whilst the plain merges with the South Lancashire Plain in the embayment occupied by Manchester to the north. In detail, the plain comprises two areas with distinct characters, the one to the west of the Mid Cheshire Ridge and the other, larger part, to its east. The plain is the surface expression of the Cheshire Basin, a deep sedimentary basin that extends north into Lancashire and south into Shropshire. It assumed its current form as the ice-sheets of the last glacial period melted away between 20,000 and 15,000 years ago leaving behind a thick cover of glacial till and extensive tracts of glacio-flu ...

Migrant Hawker
The migrant hawker (''Aeshna mixta'') is one of the smaller species of hawker dragonflies. It can be found away from water but for breeding it prefers still or slow-flowing water and can tolerate brackish sites. The flight period is from July to the end of October. ''A. mixta'' occurs in North Africa, southern and central Europe to the Baltic region. Identification ''A. mixta'' is a small ''aeshna'' which appears dark in flight. It is similar in appearance to other aeshnas but has a characteristic "golf-tee" shaped mark on the second segment of the abdomen (S2) which is diagnostic. In flight it looks like a small Emperor dragonfly with a blue abdomen which, when seen from the side, curves down. The main identification problem in the field is distinguishing this species from '' A. affinis'' where the two species fly together. The markings on the side of the thorax are different in '' A. affinis'' and ''A. mixta''. In '' A. affinis'' the sides of the thorax are greeny yellow with ...
