The main canal network (MCN) of Danube-Tisza-Danube Hydrosystem (HS DTD) on the territory of Backa region (Serbia) supports the vascular flora that comprises 177 taxa - 175 species, one subspecies and one variety. The canals Vrbas-Bezdan and Jegricka are floristically richest, containing 118 and 111 taxa, respectively. The canal Prigrevica - Bezdan, Bezdan - Baja and Backi Petrovac - Karavukovo are floristically poorest, with 24, 50 and 59 taxa, respectively. Of the total number of detected taxa, 74 are hydrophytes. Among these, there are 21 submersed, 14 floating, and 39 emersed plant species. The vegetation comprises aquatic associations of the several classes. The determined aquatic and semiaquatic vegetation is increasingly becoming a hindrance to the use and maintenance of the studied hydrosystem. In order to increase water quality and usefulness of the canals, it is necessary to dredge the canals on a regular basis, construct facilities for the treatment of industrial and municipal wastewaters alongside the canals, improve the efficiency of water utilization and maintain an operative water table in the canal network by supplying water from the Danube River.
