A Biosphere is an area in which people work to balance the conservation of biodiversity with its sustainable use.
The area around the river Dyfi is a special place to live, work and to visit - special for its people, its culture and its outstanding environment.
It hosts some of the finest examples of special landscapes and wildlife areas in Europe. And in addition has a community that cares about, and for, this special place.
The lower Dyfi Valley was first designated a Biosphere in the 1970s, but rule changes in the 1990s meant sites had to reapply under new criteria. After extensive local consultation, the Dyfi Biosphere Partnership asked UNESCO to re-register a much bigger area.
Jane Davidson, Minister for the Environment, Sustainability & Housing, announced UNESCO's agreement in June 2009.
