Hen Reedbeds is a 55 hectare nature reserve near the North Sea coast of the English county of Suffolk. The reserve is located in the Blyth valley between Reydon and Blythburgh, approximately 2.5 miles (4.0 km) west of Southwold. The marshes make up part of the Suffolk Coast National Nature Reserve along with reserves at Walberswick and Dingle Marshes. [1] [2]

North Sea marginal sea of the Atlantic Ocean

The North Sea is a marginal sea of the Atlantic Ocean located between the United Kingdom, Denmark, Norway, Sweden, Germany, the Netherlands, Belgium and France. An epeiric sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 kilometres (600 mi) long and 580 kilometres (360 mi) wide, with an area of 570,000 square kilometres (220,000 sq mi).

England Country in north-west Europe, part of the United Kingdom

England is a country that is part of the United Kingdom. It shares land borders with Wales to the west and Scotland to the north-northwest. The Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight.

County Geographical and administrative region in some countries

A county is a geographical region of a country used for administrative or other purposes, in certain modern nations. The term is derived from the Old French conté or cunté denoting a jurisdiction under the sovereignty of a count (earl) or a viscount. The modern French is comté, and its equivalents in other languages are contea, contado, comtat, condado, Grafschaft, graafschap, Gau, etc..

Contents

The reserve is owned by the Suffolk Wildlife Trust and is managed in conjunction with Natural England and the RSPB. [2] [3] It is part of the Minsmere-Walberswick Heaths and Marshes Site of Special Scientific Interest, as well as being a Natura 2000 site, a Ramsar Site and within the Suffolk Coast and Heaths Area of Outstanding Natural Beauty. [3] [4]

Suffolk Wildlife Trust

Suffolk Wildlife Trust (SWT) describes itself as the county's "nature charity – the only organisation dedicated wholly to safeguarding Suffolk's wildlife and countryside." It is a registered charity, and its headquarters is at Brooke House in Ashbocking, near Ipswich. It was founded in 1961, and is one of 47 wildlife trusts covering the Great Britain and Northern Ireland. As of March 2017, it has 13,200 members, and it manages 3,120 hectares of land in 60 nature reserves, most of which are open to the public. It had an income of £3.9 million in the year to 31 March 2017.

Natural England is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. It is responsible for ensuring that England's natural environment, including its land, flora and fauna, freshwater and marine environments, geology and soils, are protected and improved. It also has a responsibility to help people enjoy, understand and access the natural environment.

Site of Special Scientific Interest Conservation designation denoting a protected area in the United Kingdom

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".

The reserve was created in 1999 from an area of degraded grassland adjacent to the A1095 road. [5] [6] It was specifically created to provide a range of freshwater habitats and is an important site for bitterns and marsh harriers within the UK. [1] [3] [6]

A1095 road road in England

The A1095 road is an A road in the English county of Suffolk. It runs from Southwold on the North Sea coast to the A12 London to Great Yarmouth road at Henham between Blythburgh and Wangford. It is around 4 miles (6.4 km) in length and is single carriageway throughout. The entire length of the road lies within the Suffolk Coast and Heaths Area of Outstanding Natural Beauty.

Eurasian bittern species of bird

The Eurasian bittern or great bittern is a wading bird in the bittern subfamily (Botaurinae) of the heron family Ardeidae. There are two subspecies, the northern race breeding in parts of Europe and Asia, as well as on the northern coast of Africa, while the southern race is endemic to parts of southern Africa. It is a secretive bird, seldom seen in the open as it prefers to skulk in reed beds and thick vegetation near water bodies. Its presence is apparent in the spring, when the booming call of the male during the breeding season can be heard. It feeds on fish, small mammals, fledgling birds, amphibians, crustaceans and insects.

Marsh harrier

The marsh harriers are birds of prey of the harrier subfamily. They are medium-sized raptors and the largest and broadest-winged harriers. Most of them are associated with marshland and dense reedbeds. They are found almost worldwide, excluding only the Americas.

Habitats

The reserve is a mix of wetland habitats, including reedbeds, fens, dykes and pools. [1] [3] [6] It was designed to provide a breeding site for bitterns. [3] Other key species seen at the site include marsh harriers, herons, bearded tits, four-spotted chaser dragonflies and hairy dragonflies as well as mammals including otters and water voles. [1] Large roosts of starlings have been common at the reserve during autumn since 2003. [7]

Four-spotted chaser species of insect

The four-spotted chaser, known in North America as the four-spotted skimmer, is a dragonfly of the family Libellulidae found widely throughout Europe, Asia, and North America.

Hairy dragonfly species of insect

Brachytron is a monotypic genus of European dragonfly of the family Aeshnidae containing the hairy dragonfly, also known as the hairy hawker or spring hawker.

Otter subfamily of mammals

Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the weasel family Mustelidae, which also includes badgers, honey badgers, martens, minks, polecats, and wolverines.

The reserve is seen as an example of the effective management of habitats in the face of coastal erosion and sea level rise along the Suffolk coast. [6]

Coastal erosion The loss or displacement of land along the coastline due to the action of waves, currents, tides. wind-driven water, waterborne ice, or other impacts of storms

There are two common definitions of coastal erosion. It is often defined as the loss or displacement of land along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. In this case, landward retreat of the shoreline, measured to a given spatial datum, is described over a temporal scale of tides, seasons, and other short-term cyclic processes. Alternatively, it is defined as the process of long-term removal of sediment and rocks at the coastline, leading again to loss of land and retreat of the coastline landward. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural.

Sea level rise The current long-term trend for sea levels to rise mainly in response to global warming.

Since at least the start of the 20th century, the average global sea level has been rising. Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in). More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017, which is a trend of roughly 30 cm (12 in) per century. This acceleration is due mostly to human-caused global warming, which is driving thermal expansion of seawater and the melting of land-based ice sheets and glaciers. Between 1993 and 2018, thermal expansion of the oceans contributed 42% to sea level rise; the melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Climate scientists expect the rate to further accelerate during the 21st century.

Facilities

A car park is maintained at the reserve. Way marked trails, some of which are wheelchair accessible, guide visitors around the site with a range of viewing platforms and hides. [3]
