Comparative analysis of species composition in invasive species (Lantana camara) eradicated and non-eradicated forest area of Dindigul forest division of Tamil Nadu

Abstract

The present work examined the impact of Lantana camara invasion on species diversity in tropical forest of Palani Forest Range, Dindigul Forest Division, Tamil Nadu, India. Simple random sampling techniques were used for vegetation analysis. In the study area, 16 tree species, 13 shrubs and 9 herbs were documented in Lantana camara eradicated area. In non eradicated area, 12 tree species, 8 shrubs and 6 herbs were documented. It is interesting to note that, the density of trees, shrubs and herbs were high in Lantana camara eradicated area with superior ground vegetation. This study confirms the superior regeneration and high density of native flora (trees, shrubs and herbs) in Lantana camara eradicated area and this would also help in protecting the native flora.
