Prof. Adam Kleczkowski (Dept. of Mathematics and Statistics, University of Strathclyde) is a member of the PHCs Science, Advisory and Response Team and has kindly produced a blog for the PHC in which he writes about the history of Spruce forests in Europe, and the lessons that need to be learned and incorporated into decision making for Scotland's forests moving forward; i.e. the plant health and climate change issues that they may face over the coming years.
