In this paper, we approach an issue of importance in ecological reconstruction related to the dynamics of plant species on fallows in the Faget – Margina – Cosava area (Timis County). The area under study covers 400 km 2 if we take into account all the fallows aged 1-7 after grain or tillage crops. In the study of the flora, we used the two steps – field and lab – and phyto-coenologic research in the area are based on the principles of the Central-European floristic school with broad application in the study of the vegetal cover in Europe and applied for the first time in Romania by Borza (1984). As a result of the study on the sampling areas we managed to inventory the superior plant species on the fallows and the characteristics of the flora and vegetation (number of families, number of species, height of the vegetal cover, stratification, and mosaic-like configuration), and phyto-geographical, biological, ecological, and economic indices. In this paper we also refer to the evolving trends of the phyto-coenoses, the changes it undergoes, its dynamics, and man-made activities
