Transformation to continuous cover forestry at Clocaenog Forest
This case study describes the transformation of Clocaenog Forest in Wales to continuous cover forestry (CCF) as part of a national initiative launched in 2001 by the Forestry Commission to promote sustainable and diverse forest management. CCF aims to maintain forest structure and species diversity by avoiding clear-felling, instead using selective felling and regeneration techniques. The site has been a key research area for over two decades, testing various methods to convert even-aged stands to CCF and studying their effects on growth, yield, and regeneration.
Clocaenog Forest, managed for multiple objectives including timber, recreation, tourism, and conservation, faces climate change risks such as increased temperatures, storm events, windthrow, and higher pest and disease pressures. Its upland location, with exposure to winter storms and limited species diversity, makes it vulnerable to wind damage and biological threats like Phytophthora ramorum in larch stands. However, the development of natural regeneration and diversification strategies offers opportunities to enhance resilience.
The management approach involves trialling different CCF techniques in permanent 1-hectare plots, including control areas, varied thinning regimes, shelterwood systems, natural regeneration, and underplanting with shade-tolerant species. Over 15 years, these methods have provided valuable insights into their impact on forest growth, resilience, and biodiversity. The lessons learned emphasize the importance of simplicity, good communication, trial and adaptation, and collaboration among researchers, managers, and operators.
The goal is to create a more structurally and species diverse forest that can better withstand climate change and pests, while still meeting production and conservation objectives. The experience at Clocaenog Forest has demonstrated that CCF can be effectively implemented as a climate adaptation strategy, serving as a model for other public and private forests across the UK. The forest now exemplifies resilient, diverse woodland management that balances multiple objectives and promotes forest health in a changing climate.

Key takeaways
- Transformation to continuous cover forestry (CCF) enhances forest resilience and biodiversity.
- Since 2001, Clocaenog Forest has applied CCF principles to create more diverse structures and species composition, improving its adaptation to climate change risks.
- Research and experimentation at Clocaenog have identified effective methods for converting even-aged stands to CCF.
- Several distinct management treatments, including thinning strategies and regeneration techniques, have been tested over two decades, demonstrating their impacts on growth, yield, and biodiversity.
- CCF management in Clocaenog has evolved into the standard practice, contributing to improved forest resilience and multi-objective delivery.
- The practical experience and scientific insights gained have been adopted across the forest, supporting objectives like timber production, recreation, and conservation amid climate change challenges.
- Adapting forest management to climate change involves managing vulnerabilities such as wind damage and pest outbreaks.
- Clocaenog's exposed upland location and limited species range make it susceptible to windthrow and pests like Phytophthora ramorum, necessitating ongoing adaptive techniques.
- Collaborative research, monitoring, and flexible management approaches are crucial for successfully implementing CCF.
- The case study emphasizes the importance of shared understanding, experimentation, and learning from failures to develop robust management systems tailored to site-specific conditions.
- CCF provides a model for climate adaptation that balances diverse objectives in upland forests.
- The case demonstrates that integrating continuous cover principles can maintain timber, biodiversity, and recreation interests while enhancing resilience against climate impacts.
