Abstract: 1. A large number of non-native trees (NNTs) have been introduced globally andwidely planted, contributing significantly to the world's economy. Although someof these species present a limited risk of spreading beyond their planting sites, agrowing number of NNTs are spreading and becoming invasive leading to diversenegative impacts on biodiversity, ecosystem functions and human well- being. Tohelp minimize the negative impacts and maximize the economic benefits of NNTs,Brundu et al. developed eight guidelines for the sustainable use of NNTs glob-ally—the Global Guidelines for the Use of NNTs (GG-NNTs).2. Here, we used an online survey to assess perceptions of key stakeholders to-wards NNTs, and explore their knowledge of and compliance with the GG-NNTs.3. Our results show that stakeholders are generally aware that NNTs can providebenefits and cause negative impacts, often simultaneously and they consider thattheir organization complies with existing regulations and voluntary agreementsconcerning NNTs. However, they are not aware of or do not apply most of theeight recommendations included in the GG-NNTs.4. We conclude that effectively managing invasions linked to NNTs requires bothmore communication efforts using an array of channels for improving stakeholderawareness and implementation of simple measures to reduce NNT impacts (e.g. via GG-NNTs), and a deeper understanding of the barriers and reluctance ofstakeholders to manage NNT invasions.
