Abstract: The monitoring of forest pests and diseases as well as the planning and implementation of necessary control measures are important tasks of the forest protection. Thus, the various functions and performance of forests are guaranteed even in times of climate change. The report gives an overview of the situation on forest health and forest protection during the year 2012 in the Federal Republic of Germany. Like in 2011, the situation of forest health was tense and it showed a disturbing trend caused by phytophagous insects and pathogens. Against pine forest pests (Panolis flammea, Dendrolimus pini) and nun moth (Lymantria monacha) as well as oak feeding species (Tortrix viridana, Erannis defoliaria, Operophthera brumata) some aerial treatments were necessary. Furthermore the outbreak of the oak processionary moth (Thaumetopoea processionea) has continued locally and regional treatments were performed. The current oak decline - caused by a disease process of biotic and abiotic factors - is increasingly threatening. In the interest of forest protection, prevention measures are necessary, which can only realized by the regulation of leaf-eating insect pests in order to avoid further loss.
A further problem is the ash dieback, a lethal disease caused by the causal agent Hymenoscyphus pseudoalbidus. The Forest Research Institutes will intensify the research regarding selection and dissemination of resistant individuals of Fraxinus excelsior respectively physiological and genetic analysis. At the quarantine pests, in 2012 was found a multi-year infestation of the Asian long-horned beetle (Anoplophora glabripennis) in southern Germany and another invasive species, the Yellow-spotted longicorn beetle (Psacothea hilaris) has arrived in Germany.
