Abstract

Kontinentalni suhi travnjaci na karbonatnoj podlozi Slavonskoga gorja poluprirodni su tip vegetacije nastao pod antropogenim utjecajem. Kako bi se produbile spoznaje o florističkim promjenama istraživanog područja i uočile ekološke promjene, provedena su istraživanja vaskularne flore sukcesijskih stadija suhih travnjaka na istočnim padinama Psunja tijekom vegetacijske sezone 2023. Evidentirano je 170 biljnih vrsta i podvrsta, a najzastupljenije porodice bile su Fabaceae, Poaceae, Rosaceae, Asteraceae i Lamiaceae. Utvrđena je dominacija hemikriptofita i svojti eurazijskog flornog elementa. Najveća bioraznolikost zabilježena je u prvom i drugom sukcesijskom stadiju koji su predstavljeni travnjačkim i mozaičkim staništima. Na istraživanom području evidentirane su 4 ugrožene, 6 strogo zaštićenih i 3 invazivne biljne vrste. Međusobna usporedba starih (Krstonošić 2013) i novih fitocenoloških snimki na istim lokalitetima ukazala je na uznapredovale sukcesivne procese što znači da se u zadnjih 10 godina nisu provodile adekvatne mjere upravljanja takvim staništima. U cilju očuvanja iznimne biološke i krajobrazne raznolikosti istraživanog područja, potrebno je pronaći prihvatljive mjere gospodarenja travnjačkim staništima. Jedna od mogućnosti je uključenje travnjačkih staništa obuhvaćenih ovim istraživanjem u ekološku mrežu Natura 2000.

Abstract (english)

Continental dry grasslands on the carbonate base of the Slavonian Mountains are a semi-natural type of vegetation created under anthropogenic influence. To deepen our understanding of floristic changes in the researched area and to observe ecological shifts, research was conducted on the vascular flora of successional stages of dry grasslands on the eastern slopes of Psunj mountain during the 2023 growing season. A total of 170 plant species and subspecies were recorded, with the most represented plant families being Fabaceae, Poaceae, Rosaceae, Asteraceae, and Lamiaceae. The dominance of hemicryptophytes and taxa of the Eurasian floral element was established. The greatest biodiversity was recorded in the first and second stages of succession, represented by grassland and mosaic habitats. In the researched area, 4 endangered, 6 protected, and 3 invasive plant species were recorded. Mutual comparison of old (Krstonošić 2013) and new phytosociological relevés at the same localities indicated advanced successional processes, suggesting that in the last 10 years, adequate management measures for such habitats were not implemented. To preserve the exceptional biological and landscape diversity of the researched area, it is necessary to find acceptable measures for the management of grassland habitats. One possibility is the inclusion of grassland habitats covered by this research in the ecological network Natura 2000.
