The Entlebuch biosphere in Canton Lucerne covers around 400 km² and has many natural treasures. It is home to Switzerland's largest and most extensive moorland landscapes, impressive karst areas and flora and fauna of international significance. This is why Entlebuch has been designated Switzerland's first biosphere reserve by UNESCO. Extensive agricultural areas are permitted in the buffer zone adjacent to the wetlands. In the transition zones, where most of the inhabitants live, an economic system based on the principles of sustainable development is established.
