2012 Survey Summary

• Equates 70% of all larch that has been analysed across the UK both on respective PFEs and in PW
2012 Survey Summary
• Observation of disease dynamics continue to be different in different parts of the country – the more larch, the bigger the problem
• Significant new findings in SW Scotland, significant increase in S Wales, limited new findings in the Forest of Dean and SE England
• Weather conditions have been extremely conducive for Pr throughout 2012 – likely to see further infection
• Further findings generally being made in association with known infected sites (both rhodo & larch), but rapid advance of symptoms in some locations were observed over the summer
