  4. 4. 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
