In this study, researchers used GBIF-mediated occurrences to create an ecological niche model that maps the current and future patterns in India of the giant African snail (Achatina fulica), considered one of the world’s worst invasive species. Native to East Africa, the snail is known to consume 50 species of plants, regularly outcompetes native snails, and carries pathogens that cause disease in humans. 60 per cent of India faces invasion, and this study revealed three high-risk invasion hotspots: western India, parts of peninsular India, and eastern India. Models under future climate scenarios predict that these regions will be even more prone to invasion, highlighting the country’s need to control this noxious species.
