This thesis discussed the links between the present status of aquatic vegetation and the main habitat characteristics of the Carska Bara ecosystem. It is essential that the rapid spread of emergent vegetation in these water bodies is tracked by appropriate long-term monitoring of hydrology and biology. Carska Bara ecosystem is well know as important bird area and as Ramsar site. It is situated at the river firth of Begej and Tisza, 72-78 00 m elevation to the east side of Vojvodina, Serbia. Samples for physical and electro-chemical measurements were taken from 10 profiles from the surface of water bodies. All analyses were done using UV Sekomam Pastel and standard electrochemical methodology (APHA-AWWA-WEF, 1995). Within investigations of aquatic- and semi-aquatic flora and vegetation 55 characteristic class species were noted. Comparing index of diversity, as well as richeness and evenness of macrophytes at the majority of sampling sites, it is to be expected that strict nature reserve (Carska Bara) has slightly higher diversity values than Stari Begej. General overview of the life-forms specter shows domination hydrogeophyta forms (HydG), which indicate rather stable aquatic ecosystem. However, the fast spreading of emerged vegetation, particularly in the Carska Bara water bodies, signifying necessity of permanent hydro- and biomonitoring. Aquatic vegetation mapping as well as latitude and longitude of the sample sites are given in WGS 84 EGM 96 Global. They were established using GPS Geo Explorer 3 Trimble. Field survey were complemented by habitat data derived from aerial photographs or satellite imagery. 10 aquatic phytocoenoses have been recorded.
