Sažetak
The 12 km long section of the Sava River in Croatia upstream of Zagreb, has existed in the past 12 000 years of Holocene as the anabranching river. Due to the river management and upstream construction of hydropower plants with associated lakes and dams in the past hundred years this geomorphological system was shifted out of equilibrium leading in particular to accelerated river bed incision with corresponding change of the river ecosystems. Original river morphology was obliterated and river dynamics drastically changed. Longitudinal continuity of the river was disrupted by dams and downstream movement of the sediment practically stopped. Many key habitats for fish and other species such as river bars and shallows were destroyed and possibilities for their formation drastically reduced. Though exposed to significant stress, the biodiversity of this stretch is still important on the national level. The remaining ecological niches provide the shelter and nourishment for rare and endangered species supporting remains of the previous larger populations. This can be explained by the robustness of the ecological system, gradual increase of the environmental standards and in the past 10 years, to nature conservation efforts related to Natura 2000 network.
