Moorlinch SSSI
Moorlinch () is a 226.0 hectare (558.4 acre) biological Site of Special Scientific Interest at Moorlinch in Somerset, notified in 1985. Moorlinch is part of the extensive grazing marsh grasslands and ditch systems of the Somerset Levels and Moors. Lying in the Parrett Basin at the foot of the Polden Hills, the area drains by gravity into the King’s Sedgemoor Drain. The water table is high for most of the year with frequent winter flooding from high ground and surface water remaining on many fields throughout the winter and early spring. Moorlinch contains a good proportion of botanically rich ditch systems. Regularly maintained field ditches are often species-rich and diverse. Notable species include Lesser Water-plantain (''Baldellia ranunculoides''), Tubular Water-dropwort (''Oenanthe fistulosa'') and Hairlike Pondweed (''Potamogeton trichoides''). The channels and banksides support a rich fauna; rare species include the water beetle (''Hydrophilus piceus'') and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

Lesser Water-plantain
''Baldellia ranunculoides'', the lesser water-plantain, is a species of flowering plant in the family Alismataceae. Synonyms Alisma ranunculoides, Echinodorus ranunculoides, Sagittaria ranunculodes Description ''Baldellia ranunculoides'' is an aquatic plant which produced erect flowering stems that rise up to above the water surface. Each flower stalk bears one or two umbels of up to five flowers each, and often only a single flower. Each flower is in diameter, and has three petals. When not in flower, ''B. ranunculoides'' can be mistaken for lesser spearwort, ''Ranunculus flammula'', which grows in similar locations. Distribution ''Baldellia ranunculoides'' is found along the Atlantic and Baltic coast of western and northern Europe, and along the Mediterranean coasts of southern Europe, Turkey and North Africa North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hairy Dragonfly
''Brachytron'' is a monotypic genus of European dragonfly of the family Aeshnidae containing the hairy dragonfly (''Brachytron pratense''), also known as the hairy hawker or spring hawker. Description The hairy dragonfly is named for its hairy thorax, distinguishing it from other hawkers. It has a long, narrow pterostigma (the coloured, sclerotized patch on the outer region of each wing). The antehumeral stripes are usually thin and green. The hairy dragonfly has coupled, oval-shaped markings on its abdomen, blue on males and yellow on females. It is smaller than other species in the genus Aeshna ''Aeshna'', or the mosaic darners, is a genus of dragonflies from the family Aeshnidae. Species within this genus are generally known as "hawkers" (Old World) or "darners" (New World). Description These are relatively large dragonflies. T ....

Soldier Fly
The soldier flies (Stratiomyidae, sometimes misspelled as Stratiomyiidae, from Greek - soldier; - fly) are a family of flies (historically placed in the now-obsolete group Orthorrhapha). The family contains over 2,700 species in over 380 extant genera worldwide. Adults are found near larval habitats, which are found in a wide array of locations, mostly in wetlands, damp places in soil, sod, under bark, in animal excrement, and in decaying organic matter. The Stratiomyinae are a different subgroup that tends to have an affinity to aquatic environments. They are diverse in size and shape, though they commonly are partly or wholly metallic green, or somewhat wasplike mimics, marked with black and yellow or green and sometimes metallic. They are often rather inactive flies which typically rest with their wings placed one above the other over the abdomen. Etymology In English, the Stratiomidi are commonly called soldier flies, in German ''Waffenfliegen'' ("armed flies"). In the I ...

Water Beetle
A water beetle is a generalized name for any beetle that is adapted to living in water at any point in its life cycle. Most water beetles can only live in fresh water, with a few Marine (ocean), marine species that live in the intertidal zone or littoral zone. There are approximately 2000 species of true water beetles native to lands throughout the world. Many water beetles carry an air bubble, called the elytra cavity, underneath their abdomens, which provides an air supply, and prevents water from getting into the Spiracle (arthropods), spiracles. Others have the surface of their exoskeleton modified to form a Gill#Plastrons, plastron, or "physical gill", which permits direct gas exchange with the water. Some families of water beetles have fringed hind legs adapted for swimming, but most do not. Most families of water beetles have larvae that are also aquatic; many have aquatic larvae and terrestrial adults. Diet Water beetles can be either herbivores, predators, or scavengers. ...

Hairlike Pondweed
''Potamogeton trichoides'' is a species of aquatic plant known by the common name hairlike pondweed, native to Europe and western Asia where it grows in calcareous, usually nutrient-rich standing or slow-flowing water. Description Hairlike pondweed is an aquatic perennial that dies back each winter into a large number of asexually produced resting bodies called turions. There are no rhizomes. It produces slender, cylindrical or slightly compressed, branching stems usually less than a metre in length but occasionally up to 2 m. The submerged leaves are long and very narrow, typically 16–80 mm long and 0.3–1 mm wide, with the midrib occupying up to 70% of the width of the leaf near the base. They are rigid and green turning darker with age. There are no floating leaves. The inflorescence is a short spike of 3–5 flowers arising from the water on a slender peduncle. This species readily hybridizes with several other species of ''Potamogeton'' including ''P. berc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

King’s Sedgemoor Drain
King's Sedgemoor Drain is an artificial drainage channel which diverts the River Cary in Somerset, England along the southern flank of the Polden Hills, to discharge into the River Parrett at Dunball near Bridgwater. As the name suggests, the channel is used to help drain the peat moors of King's Sedgemoor. There was opposition to drainage schemes from the local inhabitants, who feared that they would lose their common grazing rights. However, the main channel was constructed between 1791 and 1795, and despite some defects, brought some relief from flooding to the area. The drain was upgraded during the Second World War, to provide a backup water supply for an armaments factory at Puriton, and again in 1972, when the Sowy River flood relief channel was built. The drain has hosted the National Fishing Championships, as it is well-stocked with fish, and is also an important haven for birds. Background The area through which the drain runs was farmed as common land when it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may b ...

River Parrett
The River Parrett flows through the counties of Dorset and Somerset in South West England, from its source in the Thorney Mills springs in the hills around Chedington in Dorset. Flowing northwest through Somerset and the Somerset Levels to its mouth at Burnham-on-Sea, into the Bridgwater Bay nature reserve on the Bristol Channel, the Parrett and its tributaries drain an area of – about 50 per cent of Somerset's land area, with a population of 300,000. The Parrett's main tributaries include the Rivers Tone, Isle, and Yeo, and the River Cary via the King's Sedgemoor Drain. The long river is tidal for up to Oath. The fall of the river between Langport and Bridgwater is only , so it is prone to frequent flooding in winter and during high tides. Many approaches have been tried since at least the medieval period to reduce the incidence and effect of floods and to drain the surrounding fields. In Anglo-Saxon times the river formed a boundary between Wessex and Dumn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
