FURTHER INFORMATION

Projects

Partitioning of resources between beech trees during drought

We will examine whether recent drought events shifted the partitioning of growth among tree size classes of beech trees and use this information to develop thinning strategies for mitigating drought impacts in lowland and montane Swiss beech forests

N-DEPEND - Is there a "Nitrogen Deposition Penalty" for Forests under Drought?

This project intends to test the "N-penalty" hypothesis for the Swiss forests. By statistical modeling and quasi-experimental analyses based on N deposition estimates, drought indices and NFI data, we assess interacting effects of N deposition and drought on forest health and productivity.

DivScaling

The main objective of this project is to elaborate how different diversity components in Swiss forest change with increasing area and how they depend on changing heterogeneity.

Datengrundlage für Biomassefunktionen

Adaptation of trees to extreme climate events

Extreme climate events are expected to become more frequent with climate warming. We test genetic differentiation in resistance to late frost and drought in silver fir populations planted in the 1980s in Swizterland and abroad.
