Bixslade
Bixslade, occasionally written Bix Slade, is a short, steep-sided, valley in the Forest of Dean, Gloucestershire. It begins on high ground at Bixhead, near Broadwell, and descends sharply to meet the Cannop Valley at Stonyhill Green. Bixslade has been quarried or mined continuously for over 500 years and has been described as ''"one of the country's finest areas of extractive industrial heritage"''. Many abandoned workings are still evident in the valley and are now home to a variety of wildlife, lichens, mosses and other plant life. Three quarries and a Freemine also continue to operate, largely hidden by the picturesque woodland. Geology The Forest of Dean sits on a basin plateau, formed of a fractured asymmetrical syncline composed of Upper Palaeozoic rocks from the Silurian, Devonian and Carboniferous periods. The rocks of the Bixslade valley consist of massive Pennant Sandstone, interbedded with shale and coal seams. Iron-ore is present in the sandstone along the nor ...

Forest Of Dean
The Forest of Dean is a geographical, historical and cultural region in the western part of the county of Gloucestershire, England. It forms a roughly triangular plateau bounded by the River Wye to the west and northwest, Herefordshire to the north, the River Severn to the south, and the City of Gloucester to the east. The area is characterised by more than of mixed woodland, one of the surviving ancient woodlands in England. A large area was reserved for royal hunting before 1066, and remained as the second largest crown forest in England, after the New Forest. Although the name is used loosely to refer to the part of Gloucestershire between the Severn and Wye, the Forest of Dean proper has covered a much smaller area since the Middle Ages. In 1327, it was defined to cover only the royal demesne and parts of parishes within the hundred of St Briavels, and after 1668 comprised the royal demesne only. The Forest proper is within the civil parishes of West Dean, Lydbrook, Cin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spion Kop Quarry
Spion Kop Quarry () is a nature reserve in Gloucestershire in the Forest of Dean. Kelham, A, Sanderson, J, Doe, J, Edgeley-Smith, M, et al., 1979, 1990, 2002 editions, 'Nature Reserves of the Gloucestershire Trust for Nature Conservation/Gloucestershire Wildlife Trust' The site is managed by the Gloucestershire Wildlife Trust and held under agreement with the Forestry Commission. The site is listed in the 'Forest of Dean Local Plan Review' as a Key Wildlife Site (KWS). Location and use The site is on Purples Hill and about one and a half miles to the east of Coleford. It lies in the middle of the Nagshead and Barnhill Plantations. It is a large, deep quarry and is considered to be the best example of a quarry in the Dean Coal Measures. The quarry's stone blocks would have been durable and much prized for buildings. The quarry is one of many in the Bixslade area which are on Pennant Sandstone. The quarry became disused in the early 20th century. Shropshire Archives (sic) h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic 006
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems o ...

Branch Line
A branch line is a phrase used in railway terminology to denote a secondary railway line which branches off a more important through route, usually a main line. A very short branch line may be called a spur line. Industrial spur An industrial spur is a type of secondary track used by railroads to allow customers at a location to load and unload railcars without interfering with other railroad operations. Industrial spurs can vary greatly in length and railcar capacity depending on the requirements of the customer the spur is serving. In heavily industrialized areas, it is not uncommon for one industrial spur to have multiple sidings to several different customers. Typically, spurs are serviced by local trains responsible for collecting small numbers of railcars and delivering them to a larger yard, where these railcars are sorted and dispatched in larger trains with other cars destined to similar locations. Because industrial spurs generally have less capacity and traffic t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloucestershire Wildlife Trust
The Gloucestershire Wildlife Trust is the Gloucestershire local partner in a conservation network of 46 Wildlife Trusts. The Wildlife Trusts are local charities with the specific aim of protecting the United Kingdom's natural heritage. The Gloucestershire Wildlife Trust is managed by a Board of Trustees elected from its membership who provide overall direction for the development of the trust and there are advisory committees. The work of the trust is carried out through staff and volunteers. History The trust was founded in 1961 and was then named the Gloucestershire Trust for Nature Conservation. Founder members included Sir Peter Scott, Christopher Cadbury and a group of other local people with the shared interest of nature conservation. The name was changed to the Gloucestershire Wildlife Trust in 1991. In 1990 Lady Scott became the trust's patron succeeding her late husband, Sir Peter Scott. Originally the trust headquarters was at Church House, Standish, which was opene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marchantiophyta
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly diff ...

Mosses
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) ''sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are app ...

Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around ...
