Our View

The Llyn Eiddwen NNR, near Aberystwyth, is described as being ‘oligotrophic-mesotrophic’, which means it is very pure and low in nutrients. This has resulted in some rare plants around the lake, including the lilac-pink water lobelia, shoreweed, floating water plantain, awlwort, quillwort and spring quillwort. The southern shore of the lake is dominated by bottle sedge, water horsetail and common cotton grass. The area surrounding the lake also has interesting plants such as heather, heath bedstraw and tormentil in spring and summer. The boggy piece of land north of the lake has carnivorous sundew, golden-yellow bog asphodel and cranberry, all growing amid the various bog mosses found there. Llyn Eiddwen is a good place to see birds including coot, mallard, teal, pochard and wigeon, while birds of prey include buzzard and red kite. Insects include the keeled skimmer and caddis fly. In turn, they provide food for wild brown trout, pike, three-spined sticklebacks and minnows.

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.
