The biogeographical regions of Switzerland (in 6 or 10 categories) were developed through a purely statistical classification process based on the Swiss flora maps of the CRSF and the fauna data of the CSCF. For more practical purposes, regional borders were adjusted to official commune borders (swisstopo, GGG25 as amended in 2000). Exceptions were the communes of Leukerbad, Mesocco and Bergell, which were divided inside their bounderies, and two regions were added. The 6 regions form the basic structure developed by the FOEN for current and future nature conservation projects across Switzerland. In order to meet further needs, these regions were broken down into 10 subregions.
