The Dyfi Biosphere (Welsh : Biosffer Dyfi) [1] is situated at the coast of south-central Wales in the estuary of the River Dyfi, and is a biosphere reserve representative of salt marshes and estuarine systems in the west of the United Kingdom. The estuary forms one of the most important wildfowl and shorebird centres in Wales and also comprises a Ramsar site.
Cors Fochno has a large expanse of primary raised mire and contains a high number of invertebrate species, including some of national and international importance. Upstream along the Dyfi Valley are remnants of native oak woodland. The site was declared in 1977, and covers an area of 1,589 hectares. [2]
Human activities in the area include pastoral farming and forestry, tourism and outdoor recreation, sustainable living and technology development; natural resource rehabilitation, management and monitoring; environmental education and interpretation and cultural development. [2]
The Dyfi is a post-glacial catchment of predominantly hill land with thin, acidic soils developed on lower Palaeozoic sedimentary strata. [2] Broadleaf woodlands, typically sessile oak or ash dominated, are a feature of the valley slopes and its many tributaries, although conifer plantations now dominate large areas. [2] The bryophyte, lichen and fern communities of the shady, damp valley woods are particularly notable, with large numbers of Atlantic species. [2] Several areas of upland moorland occur, comprising mixtures of acid grassland, blanket bog and dwarf shrub heath, often contiguous with larger upland areas and supporting important bird populations. [2]
The Dyfi is a classic bar-built estuary, and one of the foremost examples of a drying, sandy, nutrient-poor estuary. Important populations of migratory fish, birds and otter occur along with extensive areas of saltmarsh (Atlantic salt meadow). [2] The spit dune system of Ynyslas is an actively accreting system with good representation of dune community succession including marram fore-dunes and humid dune slacks. [2] The estuarine raised mire of Cors fochno is one of the largest and best preserved active raised bogs in the UK. It is a key site for climate-related research and supports important assemblages of lower plants, invertebrates and birds. [2]

Borth is a village and seaside resort in Ceredigion, Mid Wales; it is located 7 miles (11 km) north of Aberystwyth, on the Ceredigion Coast Path.

UNESCO Biosphere Reserves are environment-protected scientific-research institutions of international status that are created with the intent for conservation in a natural state the most typical natural complexes of biosphere, conducting background ecological monitoring, studying of the surrounding natural environment, its changes under the activity of anthropogenic factors.
The Golden Gate Biosphere Network is a voluntary coalition of federal, state and local government agencies, nonprofit organizations, universities, and private partners within the Golden Gate Biosphere region. The Network aims to protect the region's biodiversity and conserve its natural resources. The Network has been part of the UNESCO Man and Biosphere Programme since 1988.GGBN is also part of the US Biosphere Network as well as EuroMAB. It is recognized by UNESCO for its "significance for biological diversity conversation" and organizational efforts involving municipal authorities and private interests.
The River Dyfi, also known as the River Dovey, is an approximately 30-mile (48-kilometre) long river in Wales.
Barle Valley is a 1,540 acres (620 ha) Site of Special Scientific Interest within Exmoor National Park, situated in the counties of Devon and Somerset through which the River Barle flows. It was notified in its current form under the Wildlife and Countryside Act in 1988. The site includes the Somerset Wildlife Trust's Mounsey Wood Nature Reserve and the Knaplock and North Barton SSSI which has been notified since 1954.
The North Devon Coast is a designated Area of Outstanding Natural Beauty in Devon, England, designated in September 1959. The AONB contributes to a family of protected landscapes in the Southwest of England and a total of 38% of the region is classified by the International Union for Conservation of Nature as Category V Protected Landscapes. The twelve Areas of Outstanding Natural Beauty extend to 30% of the region, twice the proportion covered by AONBs in England as a whole and a further two National Parks, Dartmoor and Exmoor, cover an additional 7%.
Ynyslas is a small village about 1.5 miles north of Borth and 8 miles north of Aberystwyth, within the county of Ceredigion, Wales. It is sandwiched between a long sandy beach in Cardigan Bay and the beach in the Dyfi Estuary. The area between the sea and the estuary beach is made up of the Ynyslas Sand Dunes which are part of the Dyfi National Nature Reserve and home to many rare plants and animals. The sands of the estuary beach can be driven onto and parked upon. The nature reserve has a visitor centre with toilets and a small shop. At the start of some BBC 1 programmes, it shows people flying kites on the sand dunes, this was filmed at Ynyslas.
Cairnsmore of Fleet is an isolated mountain in the Southern Uplands of Scotland. The mountain forms an unafforested granite massif, whose highest point is about ten kilometres east of Newton Stewart. It is the highest of the "Solway Hills" sub-range, and the southernmost of Scotland's 219 Grahams, thus making it, or rather its subsidiary top, Knee of Cairnsmore, the most southerly mountain in Scotland. The view to the south takes in the Cree Estuary and Wigtown Bay, and extends as far as the Lake District, the Isle of Man and Snowdonia. The highest summits of the Galloway Hills can be seen to the north, and Ireland is in the view to the west.
Cors Caron is a raised bog in Ceredigion, Wales. Cors is the Welsh word for "bog". Cors Caron covers an area of approximately 349 hectares. Cors Caron represents the most intact surviving example of a raised bog landscape in the United Kingdom. About 44 different species groups inhabit the area including various land and aquatic plants, fish, insects, crustaceans, lichen, fungi, terrestrial mammals and birds.

North Devon's Biosphere Reserve is a UNESCO biosphere reserve in North Devon. It covers 55 square miles (140 km2) and is centred on Braunton Burrows, the largest sand dune system (psammosere) in England. The boundaries of the reserve follow the edges of the conjoined catchment basin of the Rivers Taw and the Torridge and stretch out to sea to include the island of Lundy. The biosphere reserve is primarily lowland farmland, and includes many protected sites including 63 Sites of Special Scientific Interest which protect habitats such as culm grassland and broadleaved woodlands. The most populous settlements in its buffer area are Barnstaple, Bideford, Northam, Ilfracombe, and Okehampton.

The Gouritz Cluster Biosphere Reserve is located in the Western Cape of South Africa. It is the 7th and largest of South Africa’s biosphere reserves; divided into four connected sectors ranging from sea level to 2,240 metres. The area is the only place in the world where three recognised biodiversity hotspots converge. The site is characterised by high endemism of plant species and threatened invertebrates including seven endemic species of the enigmatic beetle genus Colophon and 14 butterfly species. It provides a migratory route for large mammals such as the leopard and serves as a nursery for marine species.
