Stakeholders' views on the global guidelines for the sustainable use of non‐native trees

1. A large number of non-native trees (NNTs) have been introduced globally and widely planted, contributing significantly to the world's economy. Although some of these species present a limited risk of spreading beyond their planting sites, a growing number of NNTs are spreading and becoming invasive leading to diverse negative impacts on biodiversity, ecosystem functions and human well-being. To help 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 provide benefits and cause negative impacts, often simultaneously and they consider that their organization complies with existing regulations and voluntary agreements concerning NNTs. However, they are not aware of or do not apply most of the eight recommendations included in the GG-NNTs. 4. We conclude that effectively managing invasions linked to NNTs requires both more communication efforts using an array of channels for improving stakeholder awareness and implementation of simple measures to reduce NNT impacts (e.g. via GG-NNTs), and a deeper understanding of the barriers and reluctance of stakeholders to manage NNT invasions.
