Phytocoenological characteristics in poplar plantations in the protected region of the central Danube basin

Abstract

Following the water regulation along the Danube river, the area of natural forests decreases and the vegetation is fragmented. The goal of the study was to survey the recent phytocenological characteristics of the region of the protected floodplain outside the dam. We surveyed three site types in poplar plantations near Novi Sad. In the poplar plantations phytocoenological releves were made. The elevation of the study plantations is between 75 and 76 m a.s.l. The most represented species on the ground layer are the species Dactylis glomerata, Urtica dioica and Rubus caesius identified on the humofluvisol. The most represented species on the sandy part of the fluvisol were Rubus caesius, Solidago serotina, Dactylis glomerata and Equisetum arvense. The loamy form of fluvisol occurs at an elevation of 75.50 m. The most numerous species on the loamy form of the fluvisol in the flooded region were Rubus caesius, Solidago serotina, Polygonum hydropiper, Dactylis glomerata and Urtica dioica. Based on the above data, we determined the differences between ground vegetation in the study areas and in the part of the alluvial plain affected by additional moisture by both floodwater and ground water.
