Oak reaction to future climate changes in central and eastern romania

The extent of changes in future climatic conditions for oak forest ecosystems has been determined using a climatic modelling software. The HYPE software is able to forecast how certain climatic factors that lie behind extreme climatic phenomena affect forest ecosystems. The software was used to study oak forest ecosystems across sample surfaces within the Transylvania and the Moldova plateaus. The following step was to create simulations for two future climatic scenarios. In the first scenario, the increase of green house gases would be moderate (rcp-4.5), while in the second scenario, the increase would be accentuated (rcp-8.5). After the data processing, there resulted an analysis which focuses on the future changes within the climate which affect forest ecosystems located in the studied area. By analyzing all six oak stands, we can conclude that the Traian stand will be the most vulnerable one. The oak forests will be more affected in Moldova plateau then in Transilvania plateau in the future decades. These results can be used for applying the best management measures for current stands as well as for establishing decisions for installing future stands at the regions studied.
