The paper gives an overview on the results of diagnoses conducted at the Institute of Forest Protection of the BFW in 2002 within the scope of the Forest Damage Documentation and Information System. Epidemically occurring pathogens in 2002 are the Scleroderris-disease (Gremmeniella abietina), which affected about 4000 ha stands of Pinus sylvestris in the Tyrol, the Phytophthora-disease of Alder, which was observed in numerous stands of Alnus glutinosa as well as Alnus incana, both along lowland rivers and white-water streams in the Alps, and a probably new rust species (Melampsoridium hiratsukanum) on Alnus incana and glutinosa. Diplodia-blight (Sphaeropsis sapinea) of Pinus nigra austriaca in Eastern Austria and frost damages of Pseudotsuga menziesii were commonly observed in Lower Austria. Furthermore, examples for pathogens with local importance are Hypodermella-needle cast of Larix europaea (Hypodermella laricis), Cenangium-blight (Cenangium ferruginosum) of Pinus nigra austriaca, Leopard moth on deciduous trees, Green cicada (Cicadella viridis), dieback of Alnus viridis in subalpine stands, and herbicide damages.
