National Ecological Network (REN), forest area

The National Ecological Network (REN) was developed in close collaboration with cantonal authorities for the protec-tion of nature and landscapes. It issues a technical/sciencific report that presents the Swiss landscape from an ecological perspective. It shows the divisions and connections between habitats on maps in a scale of 1:500,000 and 1:100,000 and considers not only the current situation, but also the potential of the landscape. This foreward-looking, holistic approach provides a total picture of the large ecological networks in the country. Maps of specific networks show the corresponding core and distribution areas as well as the continua and corridors of the 5 specific networks. The network situation of each specific network is illustrated in another series of maps.
