The paper is a synthesis of the researches on aquatic and swamp vegetation in Banat, containing a list of the main plant associations described in Romanian Banat with their Natura 2000 habitats correspondence. Previous botanical researches on wetlands concerned the diatoms, the bryophytes, inventories of flora and vegetation, observations on the evolution of flora, vegetation dynamics analysis etc. (NEACŞU, 2008). The areas studied are the swamp, the interfluve, rivers, wet meadows, lakes (wet zones). Data processed refers to a long period of time, the first information to which we refer belong to KITAIBEL (1802, in COSTE et al., 1995). Beside thematic papers (flora and vegetation of wet zones), we took in consideration botanical monographs (e.g. COSTE, 1975), as well as ours previous studies concerning the cormophyte diversity in the main reservoirs in Timiș county (29 plant associations - NEACŞU & ARSENE, 2011); some of these rare in Banat (e.g. Leersietum oryzoides Krause 1955 em. Pass. 1957, Najadetum minoris Ubrizsy 1948 1961, Ceratophylletum demersii (Soó 1927) Hild 1956 (NEACŞU et al., 2010)). In terms of conservation, we consider important to note the species Lindernia procumbens (Krocker) Philcox, found at Surduc (NEACŞU, 2008) and Cirsium brachycephallum Juratzka, found at Călacea (TURCEAN et al., 2014), from Annexes II and IV of the Habitats Directive. Another aspect that mention here is the intrusion of invasive species (e.g. Amorpha fructicosa L., Reynoutria japonica Houtte.) in wetlands area, with negative effects on their biodiversity. Sites of Community Importance (SCI) of Natura 2000 in Banat, including 19 wetland habitat, some of these contain only the classes of aquatic and swamp vegetation. We found a poor level of knowledge of wet zones vegetation outside protected areas, as well within some sites of community importance.
