River Allen, Dorset
The River Allen is a river in the county of Dorset in South West England. It flows for and has its confluence with the River Stour in Wimborne Minster. It has two main tributaries, the Gussage Stream and the Crichel Stream. Route The River Allen starts at Wyke Farm as a winterbourne and flows down to Monkton Up Wimborne and then tracks its way to the Watercress farm, follows down to Honeybrook Farm, to a mill and then to Canford Bridge in Wimborne Minster that is the mouth of the river. The river is known as a classic chalkstream which supports a good fishery for trout and used to support a good salmonid population. A large amount of the river banks are privately owned by two estates including the Shaftsebury Estate at the source. Watermills There have been a number of corn mills on the river, Loverley Mill at Crichel survives as a Grade II listed building. Originally using two wheels, they were replaced in the early 20th century by a water turbine driving a pump to supply w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Listed Building
In the United Kingdom, a listed building or listed structure is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Northern Ireland Environment Agency in Northern Ireland. The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000. The statutory term in Ireland is " protected structure". A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings. In England and Wales, a national amenity society must be notified of any work to a listed building which involves any element of demolition. Exemption from secular listed building control is provided for some buildings in current use for worship, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angiosperm
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils are in the ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Sparganium
''Sparganium'' (bur-reed) is a genus of flowering plants, described as a genus by Linnaeus in 1753. It is widespread in wet areas in temperate regions of both the Northern and Southern Hemispheres. The plants are perennial marsh plants that can grow to 3.5 m (depending on the species), with epicene flowers. It was previously placed alone in the family Sparganiaceae. ''Sparganium'' is closely related to the Typhaceae and the APG III system (2009) includes ''Sparganium'' in that family. It has been determined from phylogenetic analysis to be the closest living relative of the genus '' Typha'' (cat-tail). Summary ''Sparganium'', commonly known as the bur-reed, is a genus of aquatic plants of shallow marshes, ponds and streams. There are 9 species found in the United States and Canada. The stem, which may be floating or emergent, emerges from a buried rhizome, which like many wetland plants, is dependent upon aerenchyma to transport oxygen to the rooting zone. The leaves are st ...

Ranunculus Aquatilis
''Ranunculus aquatilis'', the common water-crowfoot or white water-crowfoot, is a plant species of the genus ''Ranunculus'', native throughout most of Europe and western North America, and also northwest Africa. This is an aquatic plant Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that ..., growing in mats on the surface of water. It has branching thread-like underwater leaves and toothed floater leaves. In fast flowing water the floaters may not be grown. The flowers are white petaled with yellow centres and are held a centimetre or two above the water. The floater leaves are used as props for the flowers and are grown at the same time.Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''.

White Clawed Crayfish
''Austropotamobius pallipes'' is an endangered European freshwater crayfish, and the only crayfish native to the British Isles. Its common names include white-clawed crayfish and Atlantic stream crayfish. Distribution It is found from the easterly Balkan Peninsula to Spain and reaches its northerly limit in Great Britain, as well as Ireland (where it is considered introduced), where it is limited to some regions only: its highest densities are in chalk streams. ''A. pallipes'' is the only crayfish found in Ireland, occurring over limestone areas in rivers, streams, canals, and lakes. In France, ''A. pallipes'' is found in streams such as the Mornante and Sellon, two small tributaries of the Dorlay in the Loire department. It is protected as a heritage species. It has also been introduced to Corsica, Liechtenstein, and Portugal (from where it is now extirpated). It was once found across most of Great Britain; however its distribution is rapidly shrinking, and it is recorded in Yo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquatic Vegetation
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecologi ...

Crichel House
Crichel House is a Grade I listed, Classical Revival country house near the village of Moor Crichel in Dorset, England. The house has an entrance designed by Thomas Hopper and interiors by James Wyatt. It is surrounded by of parkland, which includes a crescent-shaped lake covering . The parkland is Grade II listed in the National Register of Historic Parks and Gardens. History The original Tudor house, owned by the Napier family, was largely destroyed in an accidental fire in 1742 and was rebuilt in English Baroque style for Sir William Napier by John Bastard of Blandford and Francis Cartwright, probably the contractor.John Martin Robinson"The magnificent puzzle of Crichel, one of Dorset's grandest Georgian houses" ''Country Life'' 01730 April 2019.

Winterbourne (stream)
A winterbourne is a stream or river that is dry through the summer months, a special case of an intermittent stream. Winterbourne is a British term derived from the Old English winterburna, which is equivalent to winter + burna. A winterbourne is sometimes simply called a bourne, from the Anglo-Saxon word for a stream flowing from a spring, although this term can also be used for all-year water courses. Winterbournes generally form in areas where there is chalk (or other porous rock) downland bordering clay valleys or vales. When it rains, the porous chalk holds water in its aquifer, releasing the water at a steady rate. During dry seasons the water table may fall below the level of the stream's bed, causing it to dry out. Exploitation of chalk aquifers as a domestic water source in Britain has had the effect of converting many streams and rivers into artificial winterbournes. This effect is controversial, and local campaigns have often been successful in reducing aquifer abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

River Stour, Dorset
The River Stour is a river which flows through Wiltshire and Dorset in southern England, and drains into the English Channel. The catchment area for the river and its tributaries is listed as . Toponymy It is sometimes called the Dorset Stour to distinguish it from other rivers of the same name in Kent, Suffolk and the Midlands. According to Brewer's ''Dictionary of Britain & Ireland'', the name Stour rhymes with ''hour'' and derives from Old English meaning "violent", "fierce" or the "fierce one". History The river burst its banks at Christchurch during the 2013–14 winter floods and 100 residents were evacuated. Prehistoric archaeology The Stour valley has produced rich evidence for early human (Palaeolithic) activity. Gravel pits in the lower reaches of the river (many underlying modern day Bournemouth) produced hundreds of Lower Palaeolithic handaxes when they were quarried, particular during the late 19th century and the first half of the 20th century.
