As climate change accelerates, Europe’s forests—long considered stable carbon sinks and biodiversity strongholds—are facing unprecedented environmental pressures. Monitoring these impacts is no longer optional; it is essential to managing and adapting forests in ways that ensure their survival and continued ecological function. The LIFE AForClimate project provides a valuable case study in how systematic forest monitoring can inform climate-resilient management strategies, especially in vulnerable beech forests across southern Europe.
The Climate Challenge to Forests
Forests are increasingly affected by a variety of climate-related stressors. Prolonged droughts, heatwaves, shifting precipitation patterns, and more frequent extreme weather events such as storms and wildfires are disrupting traditional growth cycles and threatening forest stability. European beech forests, in particular, are showing signs of stress, including premature leaf fall, crown dieback, and reduced regeneration capacity. These changes not only affect forest ecosystems but also reduce their ability to store carbon, regulate water cycles, and support biodiversity.
AForClimate’s Monitoring Framework
To better understand and address these challenges, the LIFE AForClimate project has developed a comprehensive monitoring strategy. Focused primarily on beech forests in Italy, the project combines ecological, climatic, and management data to evaluate how forests are responding to both natural climatic shifts and adaptive silvicultural interventions.
Key components of the monitoring system include:
- Permanent forest plots for repeated measurements of growth, regeneration, and biodiversity;
- Remote sensing and GIS tools to analyze landscape-scale changes in forest cover and health;
- Climatic data analysis, using both historical trends and real-time weather station inputs.
The team also tracks specific indicators such as tree growth rates, mortality patterns, canopy density, soil temperature and moisture, and understorey diversity—each providing clues about the forest’s resilience and stress levels.
Lessons from the Field
Initial findings from AForClimate’s pilot sites have revealed valuable insights. For example, forests with adaptive thinning practices and diversified age structures show greater resistance to drought and faster recovery after heatwaves. Monitoring has also revealed early warning signs of stress—such as reduced growth in specific elevation zones or an increase in deadwood accumulation—that can inform timely interventions.
Perhaps most importantly, the project has demonstrated how real-time data and long-term monitoring can validate the effectiveness of adaptive forest management strategies. In areas where changes were made based on monitoring feedback—such as adjusting thinning intensity or protecting regenerating species—forest health metrics improved significantly compared to control sites.
Turning Data into Action
AForClimate is not just collecting data; it is using it to make management more responsive and dynamic. Rather than relying on static forest plans developed years in advance, the project has pioneered a model in which monitoring data directly informs decision-making. Forest managers can adjust interventions in near real-time based on the forest’s observed response to climate conditions.
This approach reflects a shift toward adaptive management, where flexibility and feedback are central. It also underscores the importance of embedding monitoring systems into the forest management cycle, rather than treating them as add-ons or academic exercises.
Scaling Up and Looking Ahead
While AForClimate has achieved significant success, challenges remain. Continuous monitoring requires investment in technology, skilled personnel, and long-term commitment—resources that are not always readily available. Additionally, harmonizing data standards across regions and integrating monitoring into national policies are ongoing hurdles.
However, the project offers a strong blueprint for scaling up climate-responsive forestry. Its findings have already contributed to regional policy discussions and are being shared with forest authorities and practitioners across Europe. By aligning with broader EU strategies—such as the European Green Deal and the EU Forest Strategy—AForClimate helps position monitoring as a pillar of future forest policy.
Conclusion
The LIFE AForClimate project makes it clear: Monitoring is not a luxury—it’s a necessity. Understanding how forests respond to climate stress is the first step toward managing them more effectively and preserving their functions for future generations. As environmental uncertainty grows, the lessons from AForClimate should inspire forest managers, policymakers, and researchers to invest in robust, science-based monitoring systems—and to act on the knowledge they generate.
