Biodiversity – the diversity of habitats, species and genes – is the diversity of life. We develop the scientific basis required for monitoring and promoting biodiversity in Switzerland, and model how the biodiversity could change in the future.
Biodiversity – genetic diversity, species diversity, habitat diversity and the interrelationships within and between these three levels – is the basis of our existence. By ratifying the Rio Convention on Biological Diversity, Switzerland has undertaken to monitor, preserve and promote biodiversity. After all, it is only thanks to high biodiversity that ecosystems can render vital services, like clean water and stable soil. Biodiversity contributes to our quality of life and to the recreational value of our environment. It is also our responsibility for ethical and moral reasons to maintain species diversity as a part of biodiversity.
However, biodiversity is under threat, both in Switzerland and worldwide. Changes in land use, environmental pollution, invasive species and climate change all have a negative impact on biodiversity. To ensure that it is maintained and promoted in Switzerland in the long term, the Federal Council adopted the Swiss Biodiversity Strategy in 2012.
Research and monitoring
As a government research institute, we conduct both fundamental research and applied biodiversity research, for instance in the areas of biodiversity monitoring and analysis, mountain ecology, forest biodiversity, urban ecology and conservation genetics. With the aim of monitoring and promoting biodiversity in Switzerland, we develop methods with which biodiversity and its changes can be recorded. For example, we run the national data centres for fungi and lichens, document the population development of different groups of organisms and compile the corresponding Red Lists. We also support the national data centre for vascular plants. In the project "Monitoring the Effectiveness of Habitat Conservation in Switzerland" on behalf of the Federal Office for the Environment (FOEN), we are examining whether habitats of national importance are developing in line with their conservation aims and whether they are maintaining the same surface area and quality.
Measures to protect biodiversity are often costly. For that reason, it is important to monitor how successful they are. We develop methods for success monitoring and help to optimise implementation.
Looking back and to the future
Biodiversity is constantly changing. By drawing comparisons with historical data, we can show how, on the one hand, changes in biodiversity are affecting ecosystems. On the other hand, modelling habitat changes allows us to make statements about the future development of biodiversity. For our models, we use biodiversity data measured in the field and in experiments, geographical data and data from remote sensing.
