Sažetak
Aims:Beckmania eruciformis (L.) Host) is a critically endangered species, with extremely rare occurrence in Croatia. Through its European areal it has high coenological variability (Isoëto-Nanojuncetea, Phragmito-Magnocaricetea, Molinio-Arrhenateretea and Festuco-Puccinellietea) and its habitats range from permanently flooded to dry, to even salinized. Therefore, its historical distribution in Croatia and its vegetation affiliation has been studied. Location: Croatia, Mediterranean region, National Park Krka Methods: Fieldwork was carried out in 2015. The phytosociological relevés were sampled according to the Zürich-Montpelier approach using the adopted nine-grade Brauin-Blanquet scale and analysed in comparison to dataset from other European countries (Slovakia, Hungary, Serbia, Romania). Results and conclusion: In Croatia, the species has survived in solely one small and permanent population within National park Krka in Mediterranean part of the country. The species composition indicates regular flooding and stagnation of the water level during certain period of the year. Occurrence of the alliance Beckmanion eruciformis Soó 1933 was not confirmed for Croatia. Similarly to Slovakia and southern Serbia, Croatian population belongs to non-saline flooded vegetation of the class Phragmito-Magnocaricetea. The Croatian population is highly vulnerable and depends on continuing conservation measures.
