Wet zones have always been of great importance to humanity. The historical province of the Banat was known as a huge expanse of swamps in the past, but the current map of the region (its Romanian part) is fundamentally different, as a result of hydro-relief works. Our study is a synthesis about the evolution of the vegetation of some wet zones. Observations refer to a significant period of time. We processed and compared several hundred species and phytosociological rélevés from many location. Correlations were made between the nucleus of common species, the compared groups, the dendrogram with the grouping of the rélevés, the diversity profile of the parameters. From the processing of the data, it appears that there are significant losses in the current structure and composition of the vegetation. These are caused by a series of factors such as: reduction of the areas occupied by wet habitats, hydro-relief works, climate changes, expansion of invasive species, fragmentation, other agricultural activities.
