Along the section of the Middle Danube reach in Croatia, a large fluvial-marshy floodplain has been formed around the confluence of the Danube and the Drava Rivers. Actual protection status in category of Kopački rit Nature Park was established in 1999, including the part of the Danube River course between river km 1, 412 and 1, 382. According to the EU Habitats Directive 92/43/EEC, this area is designated in category of SCI site HR 2000394 Kopački rit (surface of 23 127, 42 ha), and makes part of the Natura 2000 ecological network in Croatia. The target and priority habitat types, listed in Annex I of the EU Habitats Directive are following: Oligotrophic to mesotrophic standing waters (3130) ; Natural eutrophic lakes (3150) ; Alluvial meadows of river valleys (6440) ; Alluvial Forests (91E0), and Riparian mixed forests (91F0). Fieldwork activities in habitat monitoring were carried out in the period from March 2021 to October 2022. Distribution, dynamics and ecological status of the surveyed habitats were determined and assessed, and 12 permanent plots were established at selected locations. The identified threats to the habitat diversity are: increased fluctuations in flooding intensity of the Danube River, increased summer air temperatures, extension of dry season, accumulation of bedload, natural succession of the wetlands, and dispersal of the invasive alien plant species. |
