Comparative analysis of species composition in invasive species (Prosopis juliflora) eradicated and non-eradicated forest area of Sathyamangalam forest division of Tamil Nadu

Abstract

The present work examined the impact of Prosopis juliflora invasion on the species diversity in tropical forest of Bhavanisagar Forest Range, Sathyamangalam Forest Division. Simple random sampling techniques were used for vegetation analysis. In the study area, 18 tree species, 19 shrubs and 15 herbs were documented in Prosopis juliflora eradicated area. In non eradicated area, 11 tree species 10 shrub species and 7 herb species were documented. It is interesting to note that, the density of trees, shrubs and herbs were high in Prosopis juliflora eradicated area with superior ground vegetation. This study confirms the superior regeneration and high density of native flora in Prosopis juliflora eradicated area and this will help in protecting the native species of forest by removing the Prosopis juliflora.
