The Dyfi Biosphere has a core area consisting of three main protected habitats:

  1. Cors Fochno- (SAC, SSSI) is one of the finest raised peat bogs in Britain
  2. Coed Cwm Einion – (SAC, SSSI) an ancient semi-natural mixed broadleaved woodland
  3. Pen Llŷn a’r Sarnau (SAC)  an area of sea, coast and estuary that support a wide range of different marine habitats and wildlife.


SAC – Special Area of Conservation

SSSI – Site of Special Scientific Interest


In addition to the vision and strategic objectives, a set of principles was agreed upon.

  1. People – their attitudes and activities – are central to the Biosphere process.
  2. The Dyfi Biosphere is a place where people’s feeling of well being is enhanced, where people are empowered and involved in deliberation, decision-making and co-delivery.
  3. The role of government and statutory organizations is to facilitate sustainable development and to encourage and enable people to take responsibility.
  4. The Dyfi Biosphere is an exemplary area, setting the benchmark for “green”, bilingual living.
  5. Our economy is becoming more self reliant and less carbon intensive, based largely on local culture, resources, products and environmental assets.
  6. Constructive change occurs, but almost incidentally as a result of protecting, strengthening and celebrating elements of life and the world which the community values and wants to pass on to future generations.
