The vascular flora of Kopački rit Nature Park (Croatia)

Kopački rit Nature Park is a large fluvial- marshy floodplain, situated in the northeastern Croatia, between courses of the Danube and the Drava Rivers. Due to exceptional biological and ecological values of this floodplain area in the middle course of the Danube River, it had been protected since 1967 ; proclaimed as Nature Park in 1999 and from 2012 is a part of the UNESCO Transboundary Biosphere Reserve Mura- Drava-Danube.

Taxonomic, ecological and phytogeographical analyses are presented. Hemicryptophytes dominate (39.3%) in the biological spectrum, followed by therophytes (23.8%), geophytes (12.6%) and hydrophytes (12.5%). In the chorological spectrum, the most numerous are plants of Eurasian floral elenent (32.8%), followed by Cosmopolites (27.4%), and European floral element (10.7%).
