List Of Sites Of Special Scientific Interest In Avon
__NOTOC__ This is a list of the Sites of Special Scientific Interest (SSSIs) in the former county of Avon, England, United Kingdom. In England the body responsible for designating SSSIs is Natural England, which chooses a site because of its fauna, flora, geological or physiographical features. Although the county of Avon no longer exists, Natural England still uses its former borders to mark one of its Areas of Search. As of 2006, there are 86 sites designated in this Area of Search, of which 38 have been designated due to their biological interest, 39 due to their geological interest, and 9 for both. Natural England took over the role of designating and managing SSSIs from English Nature in October 2006 when it was formed from the amalgamation of English Nature, parts of the Countryside Agency and the Rural Development Service. The English counties were revised under the 1974 reorganisation of local government. Until the 2010s, Natural England, which maintains the database ...

Avon Gorge
The Avon Gorge () is a 1.5-mile (2.5-kilometre) long gorge on the River Avon in Bristol, England. The gorge runs south to north through a limestone ridge west of Bristol city centre, and about 3 miles (5 km) from the mouth of the river at Avonmouth. The gorge forms the boundary between the unitary authorities of North Somerset and Bristol, with the boundary running along the south bank. As Bristol was an important port, the gorge formed a defensive gateway to the city. On the east of the gorge is the Bristol suburb of Clifton, and The Downs, a large public park. To the west of the gorge is Leigh Woods, the name of both a village and the National Trust forest it is situated in. There are three Iron Age hill forts overlooking the gorge, as well as an observatory. The Clifton Suspension Bridge, an icon of Bristol, crosses the gorge. Geology and formation The gorge cuts through a ridge mainly of limestone, with some sandstone. This particular ridge runs ...

Bourne SSSI, Avon
Bourne SSSI, Avon () is an 8.47 hectare geological Site of Special Scientific Interest near the village of Burrington, North Somerset, notified in 1992. This site is of considerable importance because it has provided detailed information upon the composition of a north Mendip Pleistocene alluvial fan. An alluvial fan is a fan-shaped deposit formed where a fast flowing stream flattens, slows, and spreads typically at the exit of a canyon onto a flatter plain. At Bourne sections have shown highly weathered gravels overlain by sandy silts and clay loams, the highest levels in the sequence showing evidence of cryoturbation In gelisols ( permafrost soils), cryoturbation (frost churning) refers to the mixing of materials from various horizons of the soil down to the bedrock due to freezing and thawing. Cryoturbation occurs to varying degrees in most gelisols. The c .... Two phases of fan sediment deposition were separated by a long period of subaerial weathering, which may re ...

Bleadon Hill
Bleadon Hill () is a 13.52 hectare geological Site of Special Scientific Interest just north of the village of Bleadon, North Somerset, notified in 1999. The site is a Geological Conservation Review site, as it shows a low ridge of calcite-cemented Pleistocene sand and gravel on its southern side. Various marine or glacial origins have been postulated for the sediments and it has even been suggested that this is a Mesozoic beach conglomerate. On the basis of the sedimentology, it is most likely that these sediments accumulated during the Quaternary when an ice sheet rested against Bleadon Hill.English Nature citation sheet for the site (accessed 9 July 2006) There is evidence or agricultural use of the land in the medieval period and possibly from Roman Roman or Romans most often refers to: * Rome, the capital city of Italy * Ancient Rome, Roman civilization from 8th century BC to 5th century AD *Roman people, the people of ancient Rome *''Epistle to the Romans'', shortened ...

Blagdon Lake
Blagdon Lake lies in a valley at the northern edge of the Mendip Hills, close to the village of Blagdon and approximately south of Bristol, England. The lake was created by Bristol Water (Bristol Waterworks Company as it was known then), when it dammed the River Yeo, starting construction in 1898, to designs by Charles Hawksley, and completing this in 1905. The Wrington Vale Light Railway was constructed primarily to bring building materials for the lake. The reservoir was formed by the construction of a dam and provided water to the pumping station which originally contained four Woolf compound rotative beam pumping engines, built by Glenfield & Kennedy of Kilmarnock, which have now been replaced by electric pumps. Two of the steam engines have been preserved, with one in working order as part of the visitor centre which also includes educational facilities for children. The pumping station is now a Grade II* listed building. The lake still provides of drinking wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barns Batch Spinney
Barns Batch Spinney () is a 0.06-hectare geological Site of Special Scientific Interest near the village of Dundry, North Somerset, notified in 1987. The English Nature citation says that Barns Batch Spinney is important because of the exposures which it provides of the lower part of the classic Inferior Oolite limestone sequence of the Dundry area. It shows rocks lying stratigraphically below the Middle and Upper Inferior Oolite Limestones seen at Dundry Main Road South Quarry. The geology at this site provides a section spanning the division of the Middle Jurassic known as the Aalenian and Bajocian Stages and a sequence of rocks placed in the subdivision known as the discites zone, named after the characteristic fossil ammonite Hyperlioceras discites ''Hyperlioceras'' is an extinct genus of cephalopod included in the ammonitid family Graphoceratidae that lived during the Bajocian stage of the Middle Jurassic.
