FURTHER INFORMATION

Projects

Sumforest - ForRISK

_{The project aims at examining the interacting effects of drought and forest management on Norway spruce and silver fir tree growth and ecophysiological mechanisms. The results will be integrated into an economic risk assessment, providing a powerful framework for adapting central European forest ecosystems to increased drought intensity.}

Projekte

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

Climate-smart forestry directions based on national Forest Inventory data

In this project we use the data of the Swiss national forest inventory to develop an assessment system that accounts for the three aspects of climate-smart forestry: mitigation, adaptation and the sustainable provision of forest ecosystem services.

Acclimation and environmental memory

Which are the main mechanisms conveying adaptation on the organ and whole tree level, how fast does acclimation occur and how long is an acclimation potential sustained?

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.
