Sažetak
Several research papers emphasize that both species composition and land cover in Mediterranean ecosystems generally recover rapidly after fire. Mediterranean species have ecological strategies for the post-fire period, such as the ability to resprout, seed bank persistence, or the ability to grow or disperse. Here an abandoned agricultural field (AAF) near Biograd na moru (Croatia) was burned by an induced fire. Fifteen rings (diameter 0.2 m2 ) were established, five for each variant: I. unburned (UB), II. medium intensity (MB) and III. high intensity (HB), and observed within 12 months. The results showed that the functional group (FG) of grasses dominated in the variant MB, in contrast to the dominance of legumes in the variant HB. Compared to AAF, the number of forbs FG slightly decreased in both burn variants (MB, HB). The dominant strategy was competitors (C), followed by ruderal plants (R), whose numbers increased slightly after burning in the MB and HB variants, while stress tolerants decreased significantly in both variants. The total cover of renewed vegetation was higher on HB than on MB. These preliminary results indicate that the intensity of HB does not promote grass survival in the first year after fire, while legumes and forbs are more resistant to higher fire intensity and therefore have a higher chance of survival.
