Biosphere reserves and national natural heritage are two important concepts in German nature conservation. Biosphere reserves are model regions that exemplify sustainable development in ecological, economic and social terms. They represent important landscape types and demonstrate the diversity of habitats and fauna in Germany.
As part of the international program "Man and the Biosphere" (MAB), biosphere reserves have been recognized by UNESCO since 1976. The aim of the UNESCO biosphere reserves is to promote a balanced relationship between man and the biosphere and to set an example. The 18 biosphere reserves in Germany cover around four percent of the country's surface area.
