This study was carried out for the Forestry Commission by SRUC.  It assesses data, literature, management approaches and governance frameworks on Oak Processionary Moth (OPM) in the Netherlands, where OPM is wide-spread,  and considers potential implications for England.  The study reviews available literature from both countries and considers potential implications for a wider outbreak in London.  It examines impacts, primarily in terms of management costs and health care costs in the context of the Dutch risk-based approach to managing OPM.      

This includes clarifying how management works in the Netherlands and what a risk-based approach entails and what it implies in English conditions.
