The decline in vitality and dieback of oak forests is increasingly present Vojvodina. This is old challenge for forestry, which again became actual. The paper used dendrochronological methods with the intention to describe trends in growth of pedunculate oak forests in Srem and trends of the water level of the Sava River and air temperature, which are defined as critical to the vitality of these forests. Predicted were water levels of Sava River in the 21st century with overview of its implications on the oak forests growth. Samples were taken from three stands in Srem (Stara Vratična, Smogva and Blate). Flows of Sava river were taken according to five climate scenarios for the periods 2012-2040 and 2042- 2070, and converted into the water levels. A trend of decrease in growth in all three stands in last 30 years was observed, together with decrease in water level and temperature rise. Predicted future water levels of the Sava River were in general lower than those in the period 1951-1981, and higher than in the period 1982-2012. The differences between the various scenarios, as well as the impossibility of adequate simulations of extreme events, leavs space for further considerations.
