Aberystwyth and the wider Dyfi Valley

The UNESCO Dyfi Biosphere inspires people and organisations to work together in creating sustainable futures we can all be proud of. It connects people with nature and cultural heritage while strengthening the local economy.

The landscapes in this part of Mid Wales run from high peat moorland, through wide estuary to sand dunes and beaches, taking in the wildlife of broadleaved woodland, coniferous forest, farmland, saltmarsh and large lowland peat bog making it a haven for wildlife.



Otters swim in the rivers, ospreys come and nest, red kites are easy to spot and dolphin pods regularly visit the beaches; there are nature reserves perfect for bird watching including the Dyfi Wildlife Centre and an RSPB reserve.

UNESCO Biosphere Reserve

The UNESCO Biosphere Reserve status offers the area recognition and opportunity rather than constraint, because the designation is voluntary rather than statutory. People, businesses and organisations take advantage of it by getting involved. The coordinating Partnership has no funding of its own, but partners can act in its name. Sometimes they bring new resources into the area such as funding and expertise.

Sustainable Development

Biosphere Reserves explore locally how sustainable livelihoods, vibrant cultures and robust economies can be based on healthy environments.

Education and Research

Biosphere Reserves are places of learning. The Dyfi Biosphere supports research to understand its environment and community.

The documents are available here.
