Reed is a common name for several tall, grass-like plants of wetlands.
The sedge warbler is an Old World warbler in the genus Acrocephalus. It is a medium-sized warbler with a brown, streaked back and wings and a distinct pale supercilium. Sedge warblers are migratory, crossing the Sahara to get from their European and Asian breeding grounds to spend winter in Africa. The male's song is composed of random chattering phrases and can include mimicry of other species. The sedge warbler is mostly insectivorous.
Phragmites is a genus of four species of large perennial reed grasses found in wetlands throughout temperate and tropical regions of the world.
A constructed wetland is an artificial wetland to treat sewage, greywater, stormwater runoff or industrial wastewater. It may also be designed for land reclamation after mining, or as a mitigation step for natural areas lost to land development. Constructed wetlands are engineered systems that use the natural functions of vegetation, soil, and organisms to provide secondary treatment to wastewater. The design of the constructed wetland has to be adjusted according to the type of wastewater to be treated. Constructed wetlands have been used in both centralized and decentralized wastewater systems. Primary treatment is recommended when there is a large amount of suspended solids or soluble organic matter.
South Milton Ley is a 162,000 square metres wetland in the South Hams, Devon, England. It was notified as a Site of Special Scientific Interest in 1976. Part of the site is managed as a nature reserve by the Devon Birdwatching and Preservation Society.
Sandbach Flashes are a group of 14 wetlands west of Sandbach in Cheshire, England. The flashes were designated as a Site of Special Scientific Interest in 1963, with a total area of 1.53 km2. There are a number of individual flashes including Bottom's Flash, Crabmill Flash, Elton Hall Flash, Fodens Flash, Groby's Flash, Ilse Pool, Moston Flashes, Pump House Flash, Railway Flash, Red Lane Tip and Pool, and Watch Lane Flash.

A hydrosere is a plant succession which occurs in an area of fresh water such as in oxbow lakes and kettle lakes. In time, an area of open freshwater will naturally dry out, ultimately becoming woodland. During this change, a range of different landtypes such as swamp and marsh will succeed each other.
Secondary treatment is the removal of biodegradable organic matter from sewage or similar kinds of wastewater. The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option. A "primary treatment" step often precedes secondary treatment, whereby physical phase separation is used to remove settleable solids. During secondary treatment, biological processes are used to remove dissolved and suspended organic matter measured as biochemical oxygen demand (BOD). These processes are performed by microorganisms in a managed aerobic or anaerobic process depending on the treatment technology. Bacteria and protozoa consume biodegradable soluble organic contaminants while reproducing to form cells of biological solids. Secondary treatment is widely used in sewage treatment and is also applicable to many agricultural and industrial wastewaters.
Yanal Bog is a 1.6 hectare biological Site of Special Scientific Interest on the southern edge of the North Somerset Levels, just north of the village of Sandford, North Somerset. It was notified as an SSSI in 1988.
Phragmites australis, known as the common reed, is a species of flowering plant in the grass family Poaceae. It is a wetland grass that can grow up to 20 feet tall and has a cosmopolitan distribution worldwide.
Most organisms involved in water purification originate from the waste, wastewater or water stream itself or arrive as resting spore of some form from the atmosphere. In a very few cases, mostly associated with constructed wetlands, specific organisms are planted to maximise the efficiency of the process.
Marievale Bird Sanctuary is a protected area in Gauteng, South Africa. It is about 15 km2 in size, and situated on the East Rand on the southern half of the Blesbokspruit wetland, a Ramsar site. The Blesbokspruit is a major perennial river in Gauteng which is flanked by extensive floodplains on either side. Nearby is the Suikerbosrand Nature Reserve.
Cape Lowland Freshwater Wetland is a critically endangered vegetation type of the Western Cape, South Africa.
Bixley Heath is a 5.1-hectare (13-acre) biological Site of Special Scientific Interest on the eastern outskirts of Ipswich in Suffolk. It is also a Local Nature Reserve owned and managed by Ipswich Borough Council.
Old River Bed, Shrewsbury is a Site of Special Scientific Interest located two miles north of Shrewsbury town centre, to the east of the A528 in Shropshire, England. It is currently owned and managed by Shrewsbury Town Council.
The Eastern Anatolian montane steppe is a temperate grasslands, savannas, and shrublands ecoregion. It is located in the Armenian Highlands, covering parts of eastern Turkey, Armenia, Azerbaijan, southern Georgia, and northwestern Iran.
A floating mat is a layer of mosses and other, especially stoloniferous, plants that grows out from the shore across the surface of a lake or pond. This type of habitat is protected and is designated in the European Habitats Directive as "LRT No. 7140 Transition and Floating Mat Bogs".
Wraysbury and Hythe End Gravel Pits is a 117.2-hectare (290-acre) biological Site of Special Scientific Interest in Wraysbury in Berkshire. It is part of South West London Waterbodies Ramsar site and Special Protection Area.
