Abstract The complex phenomenon of decline in European oak is currently triggered by changing climatic conditions and their consequences like heavy rains, local floods pest development. Especially, pathogens from Phytophthora genus profit soil saturation with water. They are alien invasive species, which attack severely damage fine roots. In drought occurring the subsequent year, many oaks die as they encounter problem water uptake. Additionally, insect defoliators followed mildew infections accelerate level tree mortality. Secondary insects, butt root usually final cause death oaks. More research needed direction to determine (i) measurable factors (e.g. chlorophyll florescence) that can indicate process has already started, (ii) correlation between decay crown symptoms (scanners, software), (iii) combination stressors stimulate best development lead high plant mortality (iv) difference caused native species.
