Book excerpt: The first section of the book includes information about how tourism-related infrastructure and activities promote biological invasions, including key pathways for non-native invasive species introductions. This section provides case studies of different organisms that are known to be introduced and/or promoted by tourism in different ecosystems or regions. The second section elaborates on known and potential impacts of invasive species on tourism and recreation, including how they may affect, positively or negatively, the economic revenue from tourism, tourist access, recreation, aesthetic values and tourists' perceptions. The last section focuses on management and policy, covering aspects of how visitors perceive invasive species and their willingness to manage them, biosecurity measures to prevent invasion related to tourism, as well as potential policy options moving forward. The book draws on a number of examples across multiple taxa, landscapes and regions of the world.
