List Of Sites Of Special Scientific Interest In Cheshire
There are 63 Sites of Special Scientific Interest (SSSIs) in Cheshire, England, covering a total area of 19,844 hectares (49,035 acres). Of these, 51 have been designated for their biological interest, 7 for their geological or geomorphological features, and 5 for both. SSSIs are governed by the Wildlife and Countryside Act 1981, which mandates that sites be selected for their "flora, fauna, or geological or physiographical features".''Guidelines for the Selection of Biological SSSIs'', Part A: "Rationale". (Nature Conservancy Council; 1989) (). Downloaded from , 14 April 2010. The body responsible for designating biological SSSIs in England is Natural England, which took over the role of designating and managing SSSIs from English Nature on its creation in 2006. Earth sciences SSSIs are notified separately by the Joint Nature Conservation Committee across the entire UK via Geological Conservation Review. Natural England, like its predecessor bodies, uses a system of areas termed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shropshire
Shropshire (; alternatively Salop; abbreviated in print only as Shrops; demonym Salopian ) is a landlocked historic county in the West Midlands region of England. It is bordered by Wales to the west and the English counties of Cheshire to the north, Staffordshire to the east, Worcestershire to the southeast, and Herefordshire to the south. A unitary authority of the same name was created in 2009, taking over from the previous county council and five district councils, now governed by Shropshire Council. The borough of Telford and Wrekin has been a separate unitary authority since 1998, but remains part of the ceremonial county. The county's population and economy is centred on five towns: the county town of Shrewsbury, which is culturally and historically important and close to the centre of the county; Telford, which was founded as a new town in the east which was constructed around a number of older towns, most notably Wellington, Dawley and Madeley, which is today th ...

Bickerton Hill
Bickerton Hill refers to two low red sandstone hills that form the southern end of the Mid Cheshire Ridge in Cheshire, north-west England. The high point, Raw Head, lies on the northerly hill and has an elevation of 227 metres. Parts of the southerly hill are also known as Larkton Hill. There is evidence of settlement on the hills dating as early as the Neolithic or Bronze Age. The earthworks of an Iron Age hill fort, Maiden Castle, are located on the summit of the southerly hill; they are a Scheduled Monument. The hills have been quarried and mined for copper since the 17th century, and a grade-II-listed engine house chimney remains as a remnant of the mining industry. Several caves occur in the sandstone, some of which have a history of habitation. The Sandstone Trail, a long-distance footpath, runs along the ridge, and the area is popular with walkers. A large area of the southerly hill is protected as a Site of Special Scientific Interest (SSSI) for its biological imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Heath (habitat)
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid Cheshire Ridge
The Mid Cheshire Ridge is a range of low sandstone hills which stretch north to south through Cheshire in North West England. The ridge is discontinuous, with the hills forming two main blocks, north and south of the "Beeston Gap". The main mass of those to the south are known as the Peckforton Hills; the larger group of hills to the north do not have a collective name. Significant summits The ridge attains its highest elevation at Raw Head in the Peckforton Hills, some 227 m above sea level. Other significant summits and the parishes within which they lie, are from north to south: *Beacon Hill (150 m), (Frodsham) *Woodhouse Hill (145 m), (Frodsham) *Helsby Hill (140 m), (Helsby) *Alvanley Cliff (135 m), ( Alvanley) *Birch Hill (158 m), ( Manley) * Old Pale (176 m), ( Delamere) *Eddisbury Hill (158 m), ( Delamere) *Primrosehill (158 m), ( Delamere) *High Billinge (175 m), (Utkinton) *Luddington Hill (145 m), (Utk ...

Ancient Woodland
In the United Kingdom, an ancient woodland is a woodland that has existed continuously since 1600 or before in England, Wales and Northern Ireland (or 1750 in Scotland). Planting of woodland was uncommon before those dates, so a wood present in 1600 is likely to have developed naturally. In most ancient woods, the trees and shrubs have been cut down periodically as part of the management cycle. Provided that the area has remained as woodland, the stand is still considered ancient. Since it may have been cut over many times in the past, ancient woodland does not necessarily contain very old trees. For many species of animal and plant, ancient woodland sites provide the sole habitat, and for many others, conditions on these sites are much more suitable than those on other sites. Ancient woodland in the UK, like rainforest in the tropics, is home to rare and threatened species. For these reasons ancient woodland is often described as an irreplaceable resource, or 'critical natural ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, recent ackn ...

Pond
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may be ...

Mere (lake)
A mere is a shallow lake, pond, or wetland, particularly in Great Britain and other parts of western Europe. Derivation of the word Etymology The word ''mere'' is recorded in Old English as ''mere'' ″sea, lake″, corresponding to Old Saxon ''meri'', Old Low Franconian ''*meri'' (Dutch ''meer'' ″lake, pool″, Picard ''mer'' ″pool, lake″, Northern French toponymic element ''-mer''), Old High German ''mari'' / ''meri'' (German ''Meer'' ″sea″), Goth. ''mari-'', ''marei'', Old Norse ''marr'' ″sea″ (Norwegian ''mar'' ″sea″, Shetland Norn ''mar'' ″mer, deep water fishing qarea″, Faroese ''marrur'' ″mud, sludge″, Swedish place name element ''mar-'', French ''mare'' ″pool, pond″). They derive from reconstituted Proto-Germanic ''*mari'', itself from Indo-European ''*mori'', the same root as ''marsh'' and ''moor''. The Indo-European root ''*mori'' gave also birth to similar words in other European languages: Latin ''mare'', ″sea″ (Italian ''mare'', Spani ...

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...
