This study aimed to determine vegetation composition in the gold post-mining land of PT Sultra Utama Nickel in Bombana District. The method used in this research was the plotted path method by placing transects in accordance with purposive sampling technique. Transects were arranged systematically with a between-transects distance of 50 m The number of transects arranged were 18 transects with 3 plots each with size of each plot was 2 x 2 m, resulted in a total plot of 54 plots. Plant identification results showed that plant species found in the study area were 19 families, 30 genera, 34 species and 4 habitat. Results of vegetation analysis showed that of the 34 plant species found in the research location, plant species with the highest IVI value of 34.54% was Imperata cylindrica. The lowest IVI of 0.54% were found for Lygodium sp., Glochidion sp., Seleria levis Retz, Scoparia dulcis L., Sida rhombifolia L and Solanum torvum. The diversity index was 2.59, indicating moderate abundance category.
