The changed hydrological regime of the river Sava valley in the region of Srem (Serbia, Yugoslavia), as the consequence of the lower underground water level, resulted in the succession of numerous hydrophilic forest types to more arid varieties. This process is especially characteristic of poplar sites where 13 ecological units were defined based on previous typological studies. Because of the changes in the moisture regime, additional soil and productivity studies were undertaken aiming at the new analysis of characteristics, similarities and differences, and consequently to judge if the above number of ecological units is justified. The results of these studies show that ecological units of poplar sites in the river Sava botton land are differentiated into two significantly different groups. One group is in the class of undeveloped hydromorphic soils and includes only one ecological unit (T-84). The other group is in the classes of semigley and gley soils and it includes all the other previously defined ecological units (T-77, T-78, T-79, T-80, T-81, T-83, T-85, T-87, T-88 and T-89).
