Abstract
The forest health of Trentino was strongly conditioned by rainfall in 2008 and snowfall in the winter 2008/09. Heavy attacks by insects (larch casebearer, aphids and larch bud moth) and foliar pathogens occurred on larch in 2008. The abundant precipitations favoured also rust infections on other species, while hampered insects such as bark beetles and pine processionary moth. The heavy snowfalls in winter 2008/09 caused several tree breakages, with high losses of timber. Few pests and diseases were recorded in 2009 vegetative season, with the exception of brown headed ash sawfly, pine processionary moth and chestnut gall wasp
