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.
A large part of it is owned and managed by the National Trust. It is one of Britain's oldest nature reserves, and was the first reserve cared for by the National Trust, starting in 1899. The first parcel of land for the reserve was donated to the Trust by Charles Rothschild in 1901. The reserve includes fenland, farmland, marsh, and reedbeds. Wicken Fen is one of only four wild fens which still survive in the enormous Great Fen Basin area of East Anglia, where 99.9% of the former fens have now been replaced by arable cultivation.
Although Wicken Fen is often described[by whom?] as if it were a natural wilderness, it is neither natural nor wild; humans have been closely involved in the fen for centuries, and the reserve is still managed intensively to protect and maintain the delicate balance of species which has built up over the years.
Much of the management tries to recreate the old systems of fen working which persisted for hundreds of years, allowing species to become dependent on the practices. For example, the sedge plant, Cladium mariscus, is harvested every year and sold for thatching roofs. The earliest recorded sedge harvest at Wicken was in 1414, and ever since then, sedge has been regularly cut. The sedge-cutting has allowed an array of plants and animals to colonize the area that depend on regular clearance of the sedge in order to survive. (Many plants and animals are dependent upon regular management of vegetation in this way to keep their habitats intact.) As part of the management plan for Wicken Fen, Konik ponies and Highland cattle have been introduced to some areas in order to prevent scrub from regrowing.
The present appearance of Wicken Fen is the result of centuries of management by human beings. Many of the practices now undertaken have changed little since medieval times. In surrounding areas, the landscape has changed so completely that it is almost impossible to imagine how it must once have all looked. Only a very few places survive where it is possible to experience this primitive landscape first hand; Wicken Fen is one of these.
Tracks in and around Wicken Fen became visible on Google Street View before many towns and urban areas in Britain were covered.
Wicken Fen features the last surviving wooden windpump in the Fens. It is a small smock wind pump, which was probably built about 1912 at Adventurers' Fen for land drainage. The pump was moved to its present site and restored in 1956 by the National Trust. The Windpump now pumps water from the drainage channel up into the Fen to maintain a high water table. The nearby museums, Stretham Old Engine and Prickwillow Museum tell the story of how windpumps were succeeded by steam engines in the nineteenth century and diesel engines in the twentieth century.
The Fen has been long associated with natural history. Charles Darwin collected beetles on the site in the 1820s. Many eminent Victorian naturalists collected beetles, moths and butterflies at Wicken Fen; some of their collections can still be found in museums. From the 1920s onwards the fathers of modern ecology and conservation, the Cambridge botanists Sir Arthur Tansley and Sir Harry Godwin carried out their pioneering work on the reserve. One of the world's longest running science experiments, the Godwin Plots, continues at the Fen to this day. The Fen’s long association with science, especially nearby Cambridge University, continues to the present day with scientists actively involved in the management of the reserve, and many hundreds of research papers published about the fen over more than a century. A Bibliography can be downloaded from the Wicken website and the latest Newsletter.
The Fen is open to the public. The site is open all year round from dawn to dusk except for Christmas Day. Some paths are closed in very wet weather, and some areas are inaccessible. However, there is a boardwalk, leading to two bird hides that is open all of the time. There are several bird hides and many miles of trails for visitors to follow. There is a visitor centre, shop and café. The visitor centre has a permanent exhibition of information about Wicken Fen, its history and ecological importance. The Fen Cottage is open on Sundays, showing the life of fen people at the turn of the 20th century.
Development of the reserve
On 1 May 1899, the National Trust purchased two acres (8094 m2) for £10, and by 2016 it was over 800 acres.
The Wicken Fen Vision
The Wicken Fen Vision is a project of the National Trust to, over a 100-year period, expand the fen to a size of 56 km2 (22 sq mi). It was launched in 1999 to mark the 100th anniversary of the first acquisition. In 2001 a major acquisition was made with the purchase of Burwell Fen Farm (1.65 km2). In 2005, a 100 ha turf farm, to be called Tubney Fen, was purchased. Other purchases include Hurdle Hall Farm and Oily Hall Farm in 2009, and St Edmunds Fen in 2011. The National Trust aims to acquire further land as it becomes available, paying the market prices. As a result of the increased area of wetlands, the populations of skylarks, snipe, grey partridge, widgeon and teal have all increased with a major increase in barn owls and short-eared owls. Buzzards, hen and marsh-harriers have returned, and bitterns began breeding by 2009 for the first time since the 1930s.
The Wicken Fen Vision has great support from many people and organisations. Large sums of money have been raised from grant-awarding bodies, and from individual donors. Enlargement of the reserve has faced criticism from some residents of nearby settlements. An on-line petition entitled 'SaveOurFens' stated "We the undersigned petition the Prime Minister to Stop the National Trust flooding or junglefying our Cambridgeshire Fens!". Concerns centred on the issues of loss of agricultural land and increases in levels of local traffic and mosquito populations. A petition named 'wickenfenvision', in favour of the scheme, was also held. The two petitions ended in 2010, with a two to one vote in favour of the Wicken Fen Vision.
As part of the Vision project, the National Trust, in conjunction with Sustrans, opened a sustainable transport route connecting Wicken Fen with Anglesey Abbey and Bottisham. Work on the paths and bridges began in 2008 and was scheduled for completion in 2011. The new walking, cycle and horse riding route is 9 miles (14 km) long, and includes a number of minor roads as well as new paths and bridges to link the gap in the existing Sustrans National Cycle Route 11 between Cambridge and Ely. The project, originally called the Wicken Fen Spine Route, includes the construction of a series of new bridges over the man-made waterways known as Lodes. In July 2008, the new Swaffham Bulbeck Lode bridge and a half-mile cycle and bridleway path across White Fen were opened. Upgrades to the crossing of the River Cam at Bottisham Lock and the bridge over Burwell Lode are planned. A new bridge over Reach Lode was opened in September 2010 and an upgraded cycle way across Burwell Fen is nearly complete. The total cost of the scheme is £2 million, £600,000 of which are from Sustrans's Connect2 scheme.
Naturalists were originally drawn to Wicken because of its species richness and the presence of rarities. The Fen has therefore received a great deal of recording effort and as a result, huge species lists have accumulated. Many nationally rare species have been recorded. Surveys continue to the present day. In 1998 over 20 species new to the Fen were recorded for the first time and in 2005 another 10 were added.
Many of the species lists can be downloaded from the Fen website (see below). Wicken Fen was established as a nature reserve because of its invertebrate and plant interest. Over 8,500 species have so far been recorded on the fen, including more than 125 that are included in the Red Data Book of rare invertebrates.
The reserve supports large numbers of fly, snail, spider and beetle species. Damselflies found here include the emerald, azure, large red, red-eyed, variable and common blue; together with dragonflies such as the southern and brown hawkers, emperor, hairy dragonfly and black-tailed skimmer. The Lepidoptera fauna is very rich also, especially the moths, with over 1000 species. The nationally rare reed leopard moth is common at the site. Other local moths include cream-bordered green pea, yellow-legged clearwing and emperor. China-mark moths such as the small, brown and ringed are also seen here. Local butterflies include the green hairstreak, brown argus, speckled wood and brimstone. There are a range of freshwater and land snails including the Red Data Book species Desmoulin's whorl snail.
Notable plants include the fen violet, great fen sedge Cladium mariscus, marsh pea, greater spearwort, marsh orchids and milk parsley. There are also a number of stonewort species present in the ditches and ponds, along with flowering rush, water millefoil, and yellow and white water lilies.
The site is mainly noted for its plants and invertebrates, but many birds also can be seen, and these are particularly popular with visitors as they are often easier to observe than the more elusive insects and plants. Bird species recorded living at the site include great crested grebe, cormorant, gadwall, teal, sparrowhawk, water rail, kingfisher, snipe, woodcock, great spotted and green woodpeckers; and barn, little, tawny, long-eared and short-eared owls. Visiting birds include bittern, whooper swan, golden plover, garganey, pochard, goosander, marsh harrier, hen harrier, merlin and hobby. In season, it is most unlikely that visitors will fail to hear the 'drumming' of snipe.
Wicken Fen is divided by a man-made watercourse called "Wicken Lode". The area north of Wicken Lode, together with a smaller area known as Wicken Poors' Fen and St. Edmunds Fen, forms the classic old, undrained fen. The designated national nature reserve of 269 hectares also includes the area around the Mere, to the south of Wicken Lode. These areas contain original peat fen with communities of carr and sedge. They support rare and uncommon fenland plants such as marsh pea, Cambridge milk parsley, fen violet and marsh fern. This part of the Fen can be enjoyed from a series of boardwalks (made from recycled plastic).
The area south of the Lode is called "Adventurers' Fen" and consists of rough pasture (grading from dry to wet grassland), reedbed and pools.
The dykes, abandoned clay pits and other watercourses carry a great wealth of aquatic plants and insects, many of which are uncommon elsewhere.
