Abstract
Plant invasion is a potent threat to the species diversity around the world during the 21st century after habitat loss. Plant invasions are human introduced or of natural means like winds, birds, animals, water. It affects indigenous species diversity, soil ecology and dynamics and economics of agricultural ecosystem throughout the world. If this process of biological invasion is remained continuous for years to come then we can only transfer monocultures of species to our future generations. To preserve our indigenous species diversity, it is important to understand the process of plant invasions and their impact on species diversity in various habitats around the world.
Key words: Alien species, ecosystem, indigenous species, plant invasion.
