Traditionelle Formen der Waldnutzung in der Schweiz
Historische Waldnutzung

Viele traditionelle Waldnutzungen wie Waldweide, Streuesammeln oder Harzen verschwanden um die 1950er Jahre. Waldweide, Waldfeldbau, Aschenlauge, Beeren oder Harz: historische Waldnutzungen werden im Juni in fünf Vorträgen mit Filmausschnitten vorgestellt.

Drought in Switzerland, the ‘water tower of Europe’
Drought

How can we detect drought at an early point? What are the effects of drought on forests and sensitive ecosystems in Switzerland? There is a wide range of research conducted at WSL in view of these questions.

Primeval forest structures and biodiversity: A Swiss-Ukrainian research cooperation
Primeval forest research

The Ukrainian Carpathians still harbor extensive primeval forests, which are similar to Swiss forests with regards to tree species composition and site conditions. This makes them most valuable research objects and reference sites for comparisons with (Swiss) managed forests and forest reserves.

Forschungsprogramm Walddynamik - ein Abschluss, aber kein End
Walddynamik

Das unterdessen abgeschlossene Programm Walddynamik ist nur als erste Phase einer Forschung, deren Bedeutung angesichts des Klimawandels weiter zunehmen wird. Eine Fortführung der Arbeiten ist nicht nur sinnvoll sondern dringend.

Sturm und Windwurf
Sturm und Windwurf

Die WSL untersucht seit 14 Jahren, wie sich durch Stürme geworfene Wälder wieder erholen und hilft mit, Entscheidungshilfen für die Praxis zu entwickeln. Im Falle weiterer orkanartiger Stürme sind damit aktuelle Informationen schnell greifbar.

Microbial ecology
Microbial ecology

Soil microorganisms mediate many processes such as nitrification, denitrification, and methanogenesis that regulate ecosystem functioning and also feed back to influence atmospheric chemistry. These processes are of particular interest in terrestrial ecosystems where nutrient cycling is highly responsive to anthropogenic perturbations and soil gas releases may be sensitive to climate warming.

Available languages: German English

Rhizosphere
Rhizosphere

The rhizosphere is the part of the soil, that is influenced by the activity of roots and associated organisms such as bacteria and mycorrhizal fungi. In this research topic we want to quantify the role of rhizosphere processes in the mobilisation of nutrients and toxic substances and in the biogeochemical cycling of carbon and nutrient elements in natural ecosystems.
