Biological invasions are a major threat to biodiversity, ecosystem functioning and nature's contributions people worldwide. However, the effectiveness of invasive alien species (IAS) management measures progress toward achieving biodiversity targets remain uncertain due limited nonuniform data availability. Management success is usually assessed at local level documented in technical reports, often written languages other than English, which makes such notoriously difficult collect large geographic scales. Here we present first European assessment how managers perceive trends IAS mitigate biological invasions. We developed structured questionnaire translated into 18 disseminated it regional Europe. received responses from 1928 participants 41 countries, including 24 Union (EU) Member States. Our results reveal substantial efforts monitoring control, with plants being primary focus. Yet, there general perception an increase numbers, occupied areas, impacts across environment taxonomic groups, particularly plants, over time. This perceived consistent both EU non-EU respondents countries demonstrating more certainty their responses. also indicate lack on vertebrates invertebrates, reflecting need for targeted knowledge sharing between policymakers countries. Overall, our study suggests that Europe's current strategies insufficient substantially reduce by 2030 hence meet Kunming-Montreal Global Biodiversity Framework target.
