Developing adaptive forest management strategies to cope with climate change

Area of Science:

• Forestry science
• Climate change adaptation
• Ecological modeling

Background:

• Projected climate change poses significant threats to forest growth and composition.
• Traditional forest management strategies may require modification to ensure forest resilience.
• Adapting managed forests to changing environmental conditions is essential for long-term sustainability.

Purpose of the Study:

• To assess the impact of different forest management strategies on forest growth and composition under projected climate change.
• To compare the effectiveness of timber production maximization, climate-adapted composition, and species diversity maximization against traditional management.
• To evaluate the utility of process-oriented forest gap models in assessing management strategies.

Main Methods:

• An extended forest gap model was applied to a managed forest district in northeastern Germany.
• The model simulated three management scenarios: maximized timber production, climatically adapted composition, and maximized tree species diversity.
• Scenarios were compared against a baseline of traditional management over a 110-year development period.

Main Results:

• Management strategies significantly influence forest growth and species composition.
• Simulations indicated varying outcomes for wood production and species composition across different management approaches.
• The choice of management strategy has a substantial effect on the forest's response to climate change.

Conclusions:

• Forest management must adapt to projected climate change impacts.
• Diverse management strategies can be employed to enhance forest resilience and productivity.
• Process-oriented forest gap models are valuable tools for evaluating and informing adaptive forest management decisions.
