The biodiversity in protected areas of Terai region in Parsa Wildlife Researve (PWR) of Nepal is now under serious threat due to rapid spread of Mikania micrantha, causing decline or even extinction of native species. This research focuses on impact of Mikanina micrantha in plant-diversity. The study was conceded in buffer zone community forest of PWR. On the basis of invasion by invasive alien species, forest was divided into high, medium and low severity area respectively. Total of 30 plots were chosen throughout the study site representing a variety of cover densities of Mikania micrantha. There was statistically significant between density of regeneration and level of severity (F= 10687.5 P>0.05). Simpson and Shannon diversity of Tree on different severity sites were insignificantly different on the basis of density of tree (P>0.05, chi-square =2.87). Similarly, There was statistically insignificant difference between the density of sapling and level of severity (p>0.05 chi-square 2.26). It revealed that presence or absence of Mikania micrantha did not affect the density of tree and sapling species.
