Coastal Landscape, Duddon Estuary, River Duddon, Cumbria, England.

The Duddon Estuary is the sandy, gritty estuary of the River Duddon that lies between Morecambe Bay and the North Lonsdale coast.

 

The River Duddon and its estuary form part of the boundary of the historic county of Lancashire.

 

It opens into the Irish Sea to the north of the Furness peninsula; Walney Island forming part of its southern edge. Its 28 miles (45 km) of shoreline enclose an area of 13 square miles (35 km2), making it the second largest estuary in Cumbria after the Solway Firth and one of the six main estuaries in the historic county of Lancashire.

 

The main settlements alongside the Duddon estuary are Haverigg, Millom, Foxfield, Kirkby-in-Furness, Askam and Ireleth and Barrow-in-Furness.

 

The estuary as a whole was designated as a Site of Special Scientific Interest (SSSI) in 1990 with the amalgamation of five previously separate SSSIs: Duddon Sands, Sandscale Haws, North Walney, Hodbarrow Lagoon and Haverigg Haws. It is a Ramsar site.

 

The Duddon Estuary is significant for natterjack toads. It supports one fifth of the national population of the rare amphibian that is only found at 50 sites in the UK, of which five are in the Duddon Estuary.

 

The Duddon Estuary is an Important Bird Area. Species to be seen include pintail, red knot and common redshank with wintering waterfowl including common shelduck, red-breasted mergansers, Eurasian oystercatchers, ringed plover, dunlin and Eurasian curlew.

 

In 1998 it was designated a Special Protection Area (SPA) under the Birds Directive. It qualified under three criteria:

 

regularly there are over 20,000 wintering waterfowl.

breeding population of sandwich terns

overwintering populations of knot, pintail and redshank; populations on passage of ringed plover and sanderling.

In 2015, before the United Kingdom European Union membership referendum, there were consultations on a successful proposal that Morecambe Bay and Duddon Estuary be combined in a new SPA. This would amalgamate the existing Morecambe Bay and Duddon Estuary SPAs and would add marine areas identified as being used by foraging terns.

 

The estuary is botanically rich with salt marsh, sand dune and shingle communities, including a nationally rare shingle vegetation community at Haverigg Haws and North Walney.

 

Shingle species include sea sandwort, spear-leaved orache, sea rocket and sea kale. All the dune grasslands at Sandscale Haws, Haverigg Haws and North Walney support a rich flora with the rare dune helleborine.

 

Development has had no significant effect on the nature conservation interest of the estuary, but it is at risk from coastal defence works, grazing by agricultural stock, sea level rise, recreational pressure and bait digging.

 

Cumbria is a ceremonial county in North West England. It borders the Scottish council areas of Dumfries and Galloway and Scottish Borders to the north, Northumberland and County Durham to the east, North Yorkshire to the south-east, Lancashire to the south, and the Irish Sea to the west. Its largest settlement is the city of Carlisle.

 

The county is predominantly rural, with an area of 6,769 km2 (2,614 sq mi) and a population of 500,012; this makes it the third largest ceremonial county in England by area but the eighth-smallest by population. After Carlisle (74,281), the largest settlements are Barrow-in-Furness (56,745), Kendal (29,593), and Whitehaven (23,986). For local government purposes the county comprises two unitary authority areas, Westmorland and Furness and Cumberland. Cumbria was created in 1974 from the historic counties of Cumberland and Westmorland, the Furness area of Lancashire, and a small part of Yorkshire.

 

Cumbria is well-known for its natural beauty and much of its landscape is protected; the county contains the Lake District National Park and Solway Coast AONB, and parts of the Yorkshire Dales National Park, Arnside and Silverdale AONB, and North Pennines AONB. Together these protect the county's mountains, lakes, and coastline, including Scafell Pike, at 3,209 feet (978 m) England's highest mountain, and Windermere, its largest lake by volume.

 

The county contains several Neolithic monuments, such as Mayburgh Henge. The region was on the border of Roman Britain, and Hadrian's Wall runs through the north of the county. In the Early Middle Ages parts of the region successively belonged to Rheged, Northumbria, and Strathclyde, and there was also a Viking presence. It became the border between England and Scotland, and was unsettled until the Union of the Crowns in 1603. During the Industrial Revolution mining took place on the Cumberland coalfield and Barrow-in-Furness became a shipbuilding centre, but the county was not heavily industrialised and the Lake District became valued for its sublime and picturesque qualities, notably by the Lake Poets.
