Biodiversity ensures natural sustainability for all the life on this planet. Major drivers of global change such as climate warming, deforestation, habitat fragmentation and rapid economic development have been accelerating the invasion process since globalization. The influence of invasive alien species (IAS) has become a threat to several ecosystems. Such species are one of the biggest threats to biodiversity. Many invasive alien species reported to have successfully colonized in the area and have contributed significantly to drag some native species towards rarity and vulnerability with serious threat of extinction from this face of earth. The co-ordinated and sustained efforts are required immediately to control and eradicate them so that the biodiversity of the region is timely conserved and restored.
