In the era of Anthropocene, an ability to predict the rate at which an alien invasive species spreads its range in anew habitat in response to climate change is of growing importance. The ability of modelling tools to predict thepotential areas of spread can help in prioritizing for effective management of invasive species. Further, themethods used for modelling range spread of an alien invasive species can also be employed to assess thedistributional implications of the species in response to climate change. An exotic weed Ethulia gracilis (FamilyAsteraceae), was recently found for the first time in India growing along the road side and in fallow lands. Thisraised serious issue of concern as the species can invade rapidly. In this study, we identified potential habitats ofthe species & areas where the species can invade both under current and future climate scenarios using ecologicalniche model. Our study highlights that climate change can accelerate the potential spread of the species infuture.
