Biological invasions are increasingly recognised as a major global change that erodes ecosystems, societal well-being, and economies. However, comprehensive analyses of their economic ramifications missing for most national economies, despite rapidly escalating costs globally. Türkiye is highly vulnerable to biological owing its extensive transport network trade connections well unique transcontinental position at the interface Europe Asia. This study presents first analysis reported caused by in Türkiye. The InvaCost database which compiles invasive non-native species' monetary was used, complemented with cost searches specific Türkiye, describe spatial taxonomic attributes costly species, types costs, temporal trends. total attributed species (from 202 reporting documents) amounted US$ 4.1 billion from 1960 2022. data were only available 87 out 872 (10%) known Costs biased towards few hyper-costly taxa, such jellyfish, stink bugs, locusts. Among impacted sectors, agriculture bore highest cost, reaching 2.85 billion, followed fishery sector 1.20 billion. Management (i.e., control eradication) were, against expectations, substantially higher than damage (US$ 2.89 vs. 28.4 million). Yearly incurred rose exponentially over time, 504 million per year 2020-2022 predicted increase further next 10 years. A large deficit records compared other countries also shown, suggesting larger underestimate typically observed. These findings underscore need improved recording preventative management strategies reduce future post-invasion help inform decisions manage burdens posed species. insights emphasise crucial role standardised accurately estimating associated prioritisation communication purposes.
