Installation-free zones
Installation-free zones and landscapes provide valuable wildlife habitats and are areas in which humans can enjoy nature to the full. Secluded areas are of ecological value if the animals and plants living there are permanently protected from disturbances, which can be caused by recreational activities in particular.

In 2020, installation-free zones in Switzerland accounted for about 26 per cent of the country's surface area. They are widespread in the Alpine region, but there are very few on the Swiss Plateau and in the Jura. In the western and eastern central Alps, installation-free zones account for more than half of the area, while on the northern flank of the Alps they account for a quarter and on the southern flank of the Alps for two fifths of the region. There is a strong correllation between installation-free zones and low light emission areas.

Buildings and installations provide a clear indication of human presence. An installation-free zone is one in which there are no buildings, roads, railways, walls, antennae or other installations within an area of 0.5 by 0.5km.
Installation-free zones are identified by looking at buildings and installations in swisstopo's TLM dataset and OFCOM's dataset of mobile and broadcasting installations which were described as interfering installations in the LABES Pretest 2009 survey conducted among 1,004 persons in three regions of Switzerland.
