• Biodiversity Monitoring Switzerland

Access to previous data

Until the end of 2015, BDM comprised a total of 34 indicators largely based on third-party-program data. These indicators are no longer updated as of 2016. For the latest published versions please click on the appropriate link.

The list is in alphabetical order. It can be filtered by type of indicator by clicking on the corresponding tag.
