Our View

The Dyfi NNR at the mouth of the River Dyfi lies between Aberystwyth and Machynlleth and covers nearly 10 square miles. It includes Borth Bog (Cors Fochno), the Dyfi Estuary and the dune system at Ynyslas. The dune slacks at Ynyslas are best known for their orchids, particularly the marsh helleborine. Other orchids include the early marsh, northern marsh, bee and pyramidal. The rare sand lizard was re-introduced to the dunes in 2009. The sea between Ynyslas and Borth is a good place to see red-throated diver, gannet, shag and cormorant, and in the mouth of the estuary, sandwich, arctic, little and occasionally roseate and black terns. The birds breeding on the bog at Cors Fochno include sedge warblers, teal, water rail, redshank, common snipe, cuckoo and skylark. Winter visitors include hen harriers, merlins and peregrine falcons. Several thousand Manx shearwaters appear in the shallow waters of the Dyfi Estuary in late summer, and it provides winter refuge for large numbers of wildfowl and waders, including the only known wintering population of Greenland white-fronted geese in England and Wales.

About the area

Discover Ceredigion

The name ‘Ceredigion’ takes a bit of explanation. The town of Cardigan gives its name to the surrounding bay, but the county now uses the Welsh word for Cardiganshire – Ceredigion, pronounced with a ‘dig’. Cardigan Bay itself is a large inlet of the Irish Sea and stretches from Bardsey Island to Strumble Head. With many beaches and a unique marine life, it’s the place to come to spot bottlenose dolphins, porpoises and Atlantic grey seals. The area is a Special Area of Conservation (SAC), designated under European law to protect its species and habitats. The Ceredigion coastal path is also a major attraction.

Much of the surrounding land is fertile farmland, dotted with towns and seaside resorts such as Fishguard, New Quay, Aberaeron, Aberystwyth, Borth, Aberdyfi, Barmouth and Porthmadog. It’s also a section of coast that major rivers flow into, including the Afon Glaslyn, Teifi, Rheidol, Dyfi, Aeron, Dysynni and Mawddach. Historically, the area supported a strong maritime industry. Cardigan was a major hub, once having more than 300 ships registered in its port, seven times as many as Cardiff. Due to being something of a backwater, in many ways this area remains charmingly unspoilt. The nearby heather-clad Preseli Hills are an additional delight.
