Southlake Moor (grid reference ST370300 ) is a 196.1 hectare (484.6 acre) biological Site of Special Scientific Interest near Burrow Mump and Burrowbridge in Somerset, notified in 1985.
The Ordnance Survey National Grid reference system is a system of geographic grid references used in Great Britain, distinct from latitude and longitude. It is often called British National Grid (BNG).
The hectare is an SI accepted metric system unit of area equal to a square with 100-metre sides, 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 0.405 hectare and one hectare contains about 2.47 acres.
Burrow Mump is a hill and historic site overlooking Southlake Moor in the village of Burrowbridge within the English county of Somerset. It is a scheduled monument, with the ruined church on top of the hill a Grade II listed building.
Southlake Moor forms part of the extensive grazing marsh and ditch system of Somerset Levels and Moors. Southlake Moor is unusual in that, when conditions in the River Parrett are suitable, it may be deliberately flooded in winter by means of a sluice in the river floodbank. Some 96 species of aquatic and bankside vascular plant species have been recorded from Southlake Moor, of particular interest is the greater water-parsnip (Sium latifolium). When the moor is flooded, large numbers of wildfowl may be present; with up to 22,000 wigeon (Anas penelope), 250 Bewick's swan (Cygnus bewickii) and good numbers of pochard (Aythya ferina), teal (Anas crecca) and tufted duck (Aythya fuligula). Regular signs of the otter (Lutra lutra) are to be seen on the muddy banks of the River Parrett. The ditches on the east side of the site contain a population of the palmate newt (Triturus helveticus). [1]
The Somerset Levels are a coastal plain and wetland area of Somerset, England, running south from the Mendips to the Blackdown Hills.
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 660 square miles (1,700 km2) – about 50 per cent of Somerset's land area, with a population of 300,000.
Sium latifolium is a species of flowering plant in the family Apiaceae known by the common names great water-parsnip, greater water-parsnip, and wideleaf waterparsnip. It is native to much of Europe, Kazakhstan, and Siberia.
During 2009 and 2010 work was undertaken to upgrade sluice gates, watercourses and culverts to enable seasonal flooding during the winter diverting water from the Sowy River onto the moor. It has the capacity to hold 1.2 million cubic metres as part of a scheme by the Parrett Internal Drainage Board to restore ten floodplains in Somerset. In spring the water is drained away to enable the land to be used as pasture during the summer. [2] The scheme is also used to encourage water birds. [3]
The Sowy River is an artificial drainage channel in Somerset, England.
