Stress experiments will be conducted on existing long term observation plots using throughfall exclusion manipulations at different altitudes in different forest types.
- Throughfall exclosure experiments: characterization of drought tolerance of two major forest types
- Greenhouse experiments: characterization of drought tolerance of major conifer belt species
Mortality, biomass production, greenhouse gas balance and species-specific drought tolerance will be recorded. The experiments will lead to a greenhouse gas inventory and an assessment of resilience in the main forest types and will predict changes in the composition.
