Sažetak
Common sea-buckthorn is a glacial relict, which was, after the last glaciation, spreading to the north and higher mountain positions. In Croatia, it was widespread in Međimurje and Podravina (near Mura and Drava river – Legrad, Bukovec, Dubrava, Križovljan-grad). It is very rare in cultivation or sub-spontaneous spread, some sites are referred to the Samobor and Skradin area, and cultivated it can be found in the botanical garden of the Faculty of Science, University of Zagreb, Nepeš, Staro Brestje (Sesvete), by the road Sv. Helena-Bjelovar and in the Forest Park Adica in Vukovar. During the first half of the 20th century there was no new information on the distribution of sea buckthorn in Croatia, and in the second half of the 20th century, during the phytosociological survey of vegetation in the coastal zone of the river Drava in the wider Varaždin surroundings Trinajstić (1964, 1994) records several shrubs, without special phytosociological affiliation. As for Croatia, the first data on phytosociological features of the species H. rhamnoides brings Trinajstić (2006), based on one phytosociological relevé which, according to its floristic composition, in syntaxonomic terms belongs to the Ass. Hyppophao-Berberidetum Moor 1958.
The latest research on vegetation succession in Podravina, 26th of June 2015, showed a new locality of H. rhamnoides, north of the villages Veliki and Mali Bukovec (WGS84 Lat: 46.307054, Long: 16.727540). One
phytosociological relevé was made (Tab. 1). The analysis of the relevé shows a greater species richness (25, 15) compared to the one of Trinajstić’s (2006) and is very similar to the relevé of Moore’s (1958). So far Trinajstić-s (2006) finding of sea-buckthorn in 1966 was the last recording of this species in Croatia. As the hydrological interventions destroyed the habitats, causing the sea-buckthorn to disappear from this area, the new records of sea-buckthorn and Ass. Hyppophao-Berberdetum Moor 1958 (Berberidion vulgaris Braun-Blanquet 1950) are the only existing natural findings there. For these reasons, it should be noted that the Croatian flora is now richer for one naturally spread species, as well as the vegetation of Croatian is richer for one association which should be given an adequate importance in natural science.
