Biological invasions have detrimental effects on ecosystem functioning and biodiversity. Invasive alien species are a key driver of environmental change, and the number of introduced and invasive species is continuing to rise with climate change. Our research in this area focuses on creating baseline for monitoring invasion, recognising invasive alien species as a threat to biodiversity, and reducing uncertainty in impact classification for alien species.
