Sažetak
Aquatic macrophytes are photosynthetic organisms that grow submerged below, floating on, or growing through the water surface. The vegetation of aquatic macrophytes is of great importance as a habitat for numerous animal organisms, such as diverse groups of aquatic invertebrates (molluscs, nematodes, arthropods) and vertebrates (fishes, amphibians, reptiles, birds and mammals), providing them with food, breeding site or refuge against predation. The area of the Danube River Basin in Croatia comprises 34965 km2 or 62.5 % of the national territory. The length of the Danube course in Croatia is 137.5 km, from river km 1433 to river km 1295.5, which makes 5 % of the total Danube length. The Vuka River is a right side tributary of the Danube in Croatia, located in the south-western part of the Pannonian Plain. The total length of the Vuka River is 126 km, and catchment area is 1260 km2. Its source is located at south-eastern slopes of Krndija Mountain near village of Paučje, while its mouth into the Danube River is located in the city of Vukovar, at river km 1333. The highest water level and discharge occurs in the late spring and early summer. Annual water discharge ranging from 0.001 m3/s to 33.52 m3/s. Most of the Vuka River course is located in the lowland alluvial plain, so it features an extensively meandering course. Some of the meander loops had been cut off in the past. In the recent years, restoration and revitalization activities are completed or planned for some old meanders. Near the village of Laslovo, an old meander of the Vuka River has been restored in length of 4.3 km. Field survey was carried out in the period from June to August 2015, on selected sites along the course of the Vuka River in Osijek-Baranja and Vukovar-Srijem Counties. The aim was to record presence and distribution of the macrophyte habitat types, and to make an analysis according to arrangement of habitat types in the Croatian National Habitat Classification. Following habitat types, with assigned code, were recorded as it follows. From class A) Inland surface waters and wetland habitats: A.3.2 Free-floating and submersed hydrophytes from the vegetation class Lemnetea ; A.3.3 Rooted pondweed vegetation from the class Potamogetonetalia ; A.4.1 Marshland vegetation of the class Phragmito-Magnocaricetea, consisting of stands dominated by Phragmites, Sparganium, Sagittaria, Typha, Carex and Cyperus ; A.4.2. Amphibious vegetation from the order Cyperetalia fusci, mostly developed on dry muddy sandy bottoms. From class I)Cultivated non-forested land and habitats with weed and ruderal vegetation, habitat type with code I.1.7. Riparian nitrophilous and hygrophilous vegetation from the order Bidentetalia tripartite, was recorded.
