Impacts of invasive Chromolaena odorata on species richness, composition and seedling recruitment of Shorea robusta in a tropical Sal forest, Nepal.

Abstract

Chromolaena odorata is an invasive species known to have its adverse impacts on native diversity. We studied its impacts on plant species richness, composition and Shorea robusta seedlings in a tropical Sal forest of Nepal. We conducted field experiment along transects established in invaded and uninvaded understory vegetation. Our results show differences in native species richness and S. robusta seedling density between invaded and uninvaded plots. The invaded plots are associated with fewer species than uninvaded plots. Plot type (invaded and uninvaded), C. odorata density and cover show an 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 and beneficial impacts on people's livelihood. Therefore, control and proper management of C. odorata is needed for conserving native vegetation and preventing future problems associated with invasion.
