Quantitative ecological analyses of aquatic vegetation in the Jegricka River
Vukov, D.; Igic, R.; Borisev, M.; Janauer, Georg A.
Jegricka is a typical lowland river in Vojvodina. The agricultural area surrounding the river has significant influence on its water quality, and on the aquatic vegetation, too, through different artificial measures and pesticides draining into the river. During the first year of investigations a 34 km long reach, between the villages Temerin and Gospodinci was surveyed. Fine inorganic material builds most of the flat slopes in the upper littoral, and detritus is the most common sediment type in the littoral zone, where aquatic macrophytes are growing. Flow velocity is very low. Transparency varied between 40 and 85 cm. Land use along the banks of the Jegricka is mainly agricultural crops. A total number of 22 aquatic species was recorded. The metric Relative Plant Mass, the species distribution pattern, and some ecological indicators were analysed.
