| Abstract | Chromolaena odorata is an invasive species known to have its adverse impacts on native diversity. We studied itsimpacts on plant species richness, composition and Shorea robusta seedlings in a tropical Sal forest of Nepal. We conductedfield experiment along transects established in invaded and uninvaded understory vegetation. Our results show differencesin native species richness and S. robusta seedling density between invaded and uninvaded plots. The invaded plots areassociated with fewer species than uninvaded plots. Plot type (invaded and uninvaded), C. odorata density and cover showan effect on vegetation composition. Moreover, some of the native species are found replaced from C. odorata invaded sites.Overall, the Sal forest protects native diversity and Sal seedling recruitment besides having its high economic value andbeneficial impacts on people's livelihood. Therefore, control and proper management of C. odorata is needed for conservingnative vegetation and preventing future problems associated with invasion. |
