Results:
ICP forest monitoring points were selected with at least 5 beech or sessile oak individuals. The number of the sessile oak stands situated in zonal position near to the xeric limit was increased by field observations. The water balance model based on the Penman- Monteith evapotranspiration formula. The model runs with monthly precipitation, temperature, global radiation, vapour pressure and wind speed data, which was developed for the whole country to improve the xeric tolerance index of beech. Forest stands were selected to demonstrate the effect of climate change, increased carbon-dioxide and nitrogen on the production and diversity of the forest. Tree trunk discs were collected from selected forest stands.
