Sažetak
Today vegetation of a given area may be strongly influenced by human-driven introduction of alien species (AS): biological invasions are considered among the main factors of global changes (Mooney & Hobbs 2000) and the identification of future invaders may help in taking effective steps to prevent their disperasal and/or establishment (Mack et al. 2000). At European level, an increasing attention is given to alien invasive species (IAS) and to the development of methods for documenting the reasons for successes and failures of AS (COST Action ALIEN Challenge 2013-2017). Australian Acacia show different status of invasiveness in Europe: several display an invasive status in some Mediterranean countries, but not in others. Croatian database records reported the presence of Acacia dealbata, A. saligna and A. retinoides, but these species were not indicated as invasive. Two of them, A. dealbata and A. saligna, are certainly IAS in Italy, and the first also in Spain and Portugal. The Cost-STSM-ECOST-STSM-TD1209 was precisely devoted to survey the actual distribution of acacias along the Croatian coast, expected to offer the right environment for acacia growth, while monitoring location of plants (gardens or natural areas) and flower visitors on them. The survey brought 144 new records for Acacia dealbata, and other 13 on other acacia species, showing wider distribution of acacias in Croatia then previously thought. However, their distribution is limited to the warmest parts, with as much as 90% of all localities situated in elevation lower then 80 m.a.s.l., having absolute minimum yearly temperature above 1.1 C. Yearly precipitation ranged from 820 to 1200 mm (10% and 90% percentile). A. dealbata is highly preferred as ornamental in private (86, 8 %) and shared garden (3, 5 %). A remaining 9, 7 % of records, anyway, refer to plants grown in abandoned or unattended gardens, demonstrating the potential of this species to expand if not properly controlled. Mooney, H.
