Summary: The forest dieback in Croatia is alarming. The 11% of the damaged trees in 1987 rose to 19% in 1993. The reasons for the dieback may be found in the climatic excesses and the anthropogenetic impacts presented by the pollution of air, water and soil, all causing stress and finally, death of forest trees; in addition, various engineering operations cause severe change in their habitats. The most endangered are the fir (Abies alba Mill.); peduncled oak (Quercus robur L.); and sessile-flowered oak (Quercus petraea Liebl.), whose proportion in the Croatia forest stock is almost 40%. The research within the project refers to establishing the cause of the forest tree dieback as well as the measures for the regeneration of the devastated forests. The desired targets are the technological procedures for regeneration of these forests aimed at raising young, stable and natural stands, adapted to the changed habitats. All main scientific forestry disciplines are included in the research on the forest dieback.

Keywords: Forest dieback, emission, immission, sulphur dioxide, nitrogen oxides, photooxidants, pesticides, dendrochronology, ekological models, choice of tree species, soil amelioration, stable forest.

Research goals: Forest dieback is a global issue concerning the forests immediately impacted by techical civilization. The research is based on the knowledge, that the forest dieback is the result of industrial, urban, traffic and agricultural pollution, partly though, ty the technologies badly adapted to forest ecosystems. The micro-habitat methods helped to assess great changes in the forest soils, dry and moist sulphate deposits, nitrates and other poisons being present in Croatian forests for a considerable time now. Though different tree species react differently, sooner or later all will be destroyed through the alterations of the physiological processes in them. The results of this research should alleviate the disastrous consequences.
