Topic Biodiversity

Switzerland’s biodiversity is under pressure. Although incentive measures are having an effect locally, biodiversity remains in a poor state and continues to decline. A third of all species and half of all types of habitat in Switzerland are threatened. Occasional gains are not enough to make up for the losses caused mainly by a lack of land area, soil sealing, fragmentation, intensive use, and nitrogen and pesticide inputs. Subsidies that harm biodiversity exacerbate this negative trend. There is an urgent need for resolute action to preserve the services that biodiversity provides. Rich and resilient biodiversity also helps to mitigate climate change and its consequences.

Biodiversity: In brief

Switzerland’s biodiversity is under pressure. Although measures to promote biodiversity are showing an effect, biodiversity in general nevertheless remains in a poor state, particularly on the Swiss plateau region. Nearly half of Switzerland’s natural habitats and one third of its species are threatened. Specific local gains are insufficient to make up for the losses caused overall by a lack of available land area, soil sealing, fragmentation, intensive land use, as well as nitrogen and pesticide inputs. Subsidies that harm biodiversity exacerbate this negative trend. There is an urgent need for decisive action to safeguard services provided by biodiversity. A rich and resilient biodiversity also helps to mitigate the consequences of climate change.

Biodiversity policy

Rich biodiversity and its ecosystem services benefit not only society, but also the economy. This is why the Federal Constitution obliges the Confederation and the cantons to work together to safeguard the natural foundations of life for the long-term. The FOEN supports the Confederation in implementing a coherent biodiversity policy and in continuing to develop it further.
