Cambridgeshire is a county in the East of England, bordering Lincolnshire to the north, Norfolk to the north-east, Suffolk to the east, Essex and Hertfordshire to the south, and Bedfordshire and Northamptonshire to the west. The city of Cambridge is the county town. Following the Local Government Act 1972 restructuring, modern Cambridgeshire was formed in 1974 through the amalgamation of two administrative counties: Cambridgeshire and Isle of Ely, comprising the historic county of Cambridgeshire ; and Huntingdon and Peterborough, comprising the historic county of Huntingdonshire and the Soke of Peterborough, historically part of Northamptonshire. Cambridgeshire contains most of the region known as Silicon Fen.
Peat, also known as turf, is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers 3.7 million square kilometres (1.4 million square miles) and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of 1.5 to 2.3 m [4.9 to 7.5 ft], which is the average depth of the boreal [northern] peatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests. Across the world, peat covers just 3% of the land’s surface, but stores 42% of the Earth’s soil carbon. Sphagnum moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. The biological features of sphagnum mosses act to create a habitat aiding peat formation, a phenomenon termed 'habitat manipulation'. Soils consisting primarily of peat are known as histosols. Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition. Peat properties such as organic matter content and saturated hydraulic conductivity can exhibit high spatial heterogeneity.
Redgrave and Lopham Fens is a 127 hectare biological Site of Special Scientific Interest between Thelnetham in Suffolk and Diss in Norfolk. It is a national nature reserve, a Ramsar internationally important wetland site, a Nature Conservation Review site, Grade I, and part of the Waveney and Little Ouse Valley Fens Special Area of Conservation. It is managed by the Suffolk Wildlife Trust.
A fen is a type of peat-accumulating wetland fed by mineral-rich ground or surface water. It is one of the main types of wetlands along with marshes, swamps, and bogs. Bogs and fens, both peat-forming ecosystems, are also known as mires. The unique water chemistry of fens is a result of the ground or surface water input. Typically, this input results in higher mineral concentrations and a more basic pH than found in bogs. As peat accumulates in a fen, groundwater input can be reduced or cut off, making the fen ombrotrophic rather than minerotrophic. In this way, fens can become more acidic and transition to bogs over time.
A bog or bogland is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A baygall is another type of bog found in the forest of the Gulf Coast states in the United States. They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink.
Cladium is a genus of large sedges, with a nearly worldwide distribution in tropical and temperate regions. These are plants characterized by long, narrow (grass-like) leaves having sharp, often serrated (sawtooth-like) margins, and flowering stems 1–3 m tall bearing a much-branched inflorescence. Like many plants found in wet habitats, it has deeply buried rhizomes that can produce tall shoots with dense canopies.
Nathaniel Charles Rothschild, known as "Charles", was an English banker and entomologist and a member of the Rothschild family. He is remembered for The Rothschild List, a list he made in 1915 of 284 sites across Britain that he considered suitable for nature reserves.
Wicken is a small village on the edge of The Fens near Soham in East Cambridgeshire, ten miles north east of Cambridge and five miles south of Ely. It is the site of Wicken Fen National Nature Reserve.
Wildlife management is the management process influencing interactions among and between wildlife, its habitats and people to achieve predefined impacts. It attempts to balance the needs of wildlife with the needs of people using the best available science. Wildlife management can include wildlife conservation, gamekeeping and pest control. Wildlife management draws on disciplines such as mathematics, chemistry, biology, ecology, climatology and geography to gain the best results.
Wicken Fen is a 254.5 hectare biological Site of Special Scientific Interest west of Wicken in Cambridgeshire. It is also a National Nature Reserve, and a Nature Conservation Review site. It is protected by international designations as a Ramsar wetland site of international importance, and part of the Fenland Special Area of Conservation under the Habitats Directive.
Sir Harry Godwin, FRS was a prominent English botanist and ecologist of the 20th century. He is considered to be an influential peatland scientist, who coined the phrase "peat archives" in 1981. He had a long association with Clare College, Cambridge.
A long-term experiment is an experimental procedure that runs through a long period of time, in order to test a hypothesis or observe a phenomenon that takes place at an extremely slow rate. What duration is considered "long" depends on the academic discipline. For example, several agricultural field experiments have run for more than 100 years, but much shorter experiments may qualify as "long-term" in other disciplines. An experiment is "a set of actions and observations", implying that one or more treatments is imposed on the system under study. Long-term experiments therefore contrast with nonexperimental long-term studies in which manipulation of the system studied is impossible or undesirable.
The Cambridgeshire Lodes are a series of man-made waterways, believed to be Roman in origin, located in the county of Cambridgeshire, England. Bottisham, Swaffham Bulbeck, Reach, Burwell, Wicken and Monks Lodes all connect to the River Cam, while Soham Lode connects to the River Great Ouse. All have been navigable historically, but some are no longer officially navigable.
Woodwalton Fen is a 209 hectare biological Site of Special Scientific Interest in the parish of Woodwalton, west of Ramsey in Huntingdonshire, Cambridgeshire, England. It is a Ramsar wetland site of international importance, a National Nature Reserve, a Special Area of Conservation and a Nature Conservation Review site, Grade I. The site is managed by Natural England.
A roddon, also written as rodham, roddam or rodden, is the dried raised bed of a watercourse such as a river or tidal-creek, especially in The Fens in eastern England. Such raised silt and clay-filled beds are ideal for settlement in the less firm peat of The Fens. Many writers have followed the archaeologist Major Gordon Fowler's preference for the word roddon to define such structures though modern researchers suggest the word rodham is the more correct local word.
Emmelina argoteles is a moth of the family Pterophoridae found in Asia and Europe. It was first described by Edward Meyrick in 1922.
