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.

Contents

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

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]

Ecological characteristics

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]

Golden Gate Biosphere Network

The Golden Gate Biosphere Network is an internationally recognized voluntary coalition of federal, state, and local government agencies, nonprofit organizations, universities, and private partners within the Golden Gate Biosphere (GGB) region. The Network works towards protecting the biosphere region’s biodiversity and conserving its natural resources to maintain the quality of life for people within the region. The Network has been part of the UNESCO Man and Biosphere Programme since 1988 and is part of the US Biosphere Network and EuroMAB. It is recognized by UNESCO due to the significant biodiversity of the region, as well as the Network's efforts to demonstrate and promote a balanced relationship between humans and the biosphere.

The North Devon Coast was designated as an Area of Outstanding Natural Beauty 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 addition 7%. The North Devon Coast AONB covers 171 square kilometres (66 sq mi) of mainly coastal landscape from the border of Exmoor National Park at Combe Martin, through the mouth of the Taw & Torridge Estuary to the Cornish border at Marsland Mouth. The dune system at Braunton Burrows forms the core area of North Devon's Biosphere Reserve, the first "new style" Unesco-designated reserve in the United Kingdom. The whole of the AONB is within the Reserve boundaries.

Cairnsmore of Fleet

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 10 kilometres (6.2 mi) 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.
