Invasive alien plant species have threatened the integrity of ecosystems throughout the world. They affect not only the species diversity of native ecosystems but also threaten their biological integrity. In India, a number of invasive alien plant species have been reported and among them tropical American species like Parthenium hysterophorus L., Lantana camara L., Eupatorium odoratum L., Hyptis suaveolens (L) Poit. and Ageratum conyzoides L., are reported very troublesome and have caused adverse ecological, economic and social impact. These weeds can be seen growing in different landscapes but are luxuriantly localized in unattended forests and cultivated areas and is also documented from Jharkhand state.
