Sažetak
Habitat type 3130 Oligotrophic to mesotrophic standing waters with vegetation of the Littorelletea uniflorae and/or Isoëto-Nanojuncetea is listed in Annex I of the EU Habitats Directive 92/43/EEC. The National Habitat Classification of the Republic of Croatia designate it with a code A.4.2.1. Dwarf cyperious vegetation (Alliance Nanocpyerion Koch 1926). The habitat type 3130 is characterised by the amphibious, ephemeral annual vegetation, developed under the environmental conditions of prolonged drought period in summer or autumn and low water levels, on drying wet deposits of mud and sand. It is typical for the flat banks along the Danube and the Drava Rivers, and in the standing water bodies, such as peirphery of lakes, dried fish ponds, swamps, channels, and ditches. Floristic field survey was carried out from July to September 2022, within four Natura 2000 Sites of Community Importance (SCIs) in Croatia: HR2001309 Danube North of Kopački rit, HR2000394 Kopački rit, HR2001308 Lower Drava course, and HR2000372 Danube-Vukovar. During the survey, following Nanocyperion characteristic plants were recorded: Cyperus fuscus, C. glomeratus, C. michelianus, Gnaphalium uliginosum, Lindernia dubia, L. procumbens, and Marsilea quadrifolia, some of which are classified as endangered and vulnerable species in the Red Book of the Vascular Flora of Croatia. The new localities were recorded for the habitat type 3130 and its characteristic species, which contributes to broader knowledge on their presence and distribution in the Croatian Danube region.
