It is now widely accepted that mankind’s activities are having a discernible effect on the global climate, and these changes will impact upon the functioning of many of the planet’s natural systems. Climate change will have a variety of direct and indirect effects on forests and, thus, will have implications for forest management. This Bulletin presents current thinking on how climate change predictions for the UK may affect tree growth, health and productivity, and also how they may impact upon the functioning of forest ecosystems. The Bulletin covers the potential impacts of climate change on UK forestry but not the role that forestry may play in mitigating climate change through carbon sequestration and fossil fuel substitution.
