    • This study investigates how stakeholder perceptions, priorities, and networks influence the effectiveness of urban tree biosecurity across Europe. Using stakeholder mapping, surveys, and network analysis, the research identifies key actors, current and emerging pest threats, and the most commonly implemented biosecurity actions. Results show strong concern about several invasive pests and pathogens, highlight the importance of communication and training, and reveal that collaboration is strongest among practitioners closely involved in tree care. The study underscores the need for connected and well-coordinated stakeholders to ensure a coherent and resilient urban biosecurity system.
