In the current communication, we assessed the current spread and invasion pattern of a new invasive alien plant Wigandia urens along National Highway 58 in the Indian state of Uttarakhand. The population status of this species was assessed using systematic vegetation sampling. Ecological niche modelling was performed using maxent to predict the future spread. The study revealed that W.urens is rapidly invading along the road on rocky eroded slopes. The actual distribution of this species is 30 km. Spatial analysis revealed that a 202 km2 area along river valleys is vulnerable in the near future. It is submitted that the low-lying areas along river catchments between 300 and 1000 m elevations might be the potential niche. Therefore, mechanical removal by uprooting the whole plant at regular intervals and monitoring of invaded sites would be the practical solution. [ABSTRACT FROM AUTHOR]
