Objectives of the study
Synthesise the existing knowledge about observed and projected impacts of climate change on forests in Europe
Review the capacity of forests and forestry to adapt to climate change (adaptive capacity)
Analyse vulnerability of forests and forestry to climate change in different European regions
Review potential adaptation strategies and to survey existing and planned measures in EU member states

Survey compiling existing and planned national strategies for adapting to climate change
Conclusions and recommendations for potential adaptation options for forests and forestry in the EU27
PART 2
Evaluation of adaptation measures regarding:
•Feasibility•Reliability•Cost effectiveness

Review of potential adaptation options for each of the region
Study on impacts of climate change on European forests and options for adaptationService Contract with DG Agriculture (Dec 07 – Nov 08)
Adaptation strategies
should aim to increase the flexibility in management of vulnerable ecosystems
enhance the inherent adaptability of the species and ecosystem processes
reduce trends in environmental and social pressures that increase vulnerability to climate variability
(Hulme, P.E. 2005, J. Appl. Ecology 42, 784-794)
Reducing vulnerability involves both a reduction to the exposure to climate stress and an increase in adaptive capacity
(J.-E. Parry et al. 2005)

Adaptation strategies at different levels
2/9/2009
Stand level • forest regeneration • tending and thinning of stands• harvesting
Forest management • management planning• forest protection
Policy level• infrastructure and transport• nurseries and forest tree breeding• further adaptation options in
risk management and policy
Level of action Adaptation actions
Adaptation measures – Stand level
In regeneration species and genetic composition of the stand gets established, diversity builds up and can be manipulated
Tending and thinning improves stand structure to reduce stand susceptibility to disturbances
Harvesting activites should take place at smaller scales; development of machinery is important to secure accessibility on wet soils

Adaptation measures – Forest management level
Forest management planning should be flexible and adaptive; high need for monitoring, co-operation, decision support systems
Forest protection benefits from establishing and sustaining forest ecosystems highly diverse in tree composition, age and structure
2/9/2009
Adaptation measures – Policy levelInfrastructure and transporting; restoring groundwater regimes, improving irrigation systems and road network
Nurseries and tree breeding should produce well-adapted material for regeneration
Development and evaluation of adaptation strategies should be a participative process
More research is needed to expand the knowledge base related to adaptive forest management strategies

The adaptive capacity in the forest sector
2/9/2009
Relatively large
Relatively largeMore stronglyaffected by socio-economicconstraints
LimitedLarge forest areas are onlyextensively managed or unmanaged
Discussion points from adaptation measure survey
2/9/2009
Many ongoing and planned measures are focusing on reducing disturbance risks
Very little attention on potential benefits
More research is needed
Dissemination of information is important (Foresters, forest owners, decision makers)
Main motives of adaptation measures
1. Minimize impacts of disturbances
2. Ensure wood production
3. Ensure ecosystem services
2/9/2009
Conclusions
2/9/2009
Climate change poses great risks, but also some opportunities
Rural areas will be strongly affected
Suitable adaptation measures differ between regions
Adaptive capacity is much higher in the Boreal and Temperate Oceanic regions
The Mediterranean and Temperate Continental regions are most vulnerable and require specific support
