The study about the diversity and structure of treelet vegetation in three slope areas on the mountainous forest of mount Bawakaraeng, Regency of Gowa, Province of South Sulawesi had been done. There were 17 species of treelets throughout the study area, from 13 families and 16 genera. The Asteraceae family has the highest number of species with 3 species, followed by Fabaceae and Solanaceae which each has 2 species. Pteridium aquilinum, Chromolaena odorata, Breynia oblongifolia, and Pogostemon cablin are the species with the highest important value index. The number of treelet species ranges from 15-16. Treelet species were mostly found in the flat slope area. The Shannon-Wiener diversity index (H') ranges from 2,033-2,161 and was found to be highest on steep slopes and lowest on flat slopes. The H' has the same tendency as Simpson's Diversity Index and Evenness Index of Pielou (E) and reverse relationship with Simpson's Dominance Index. © Published under licence by IOP Publishing Ltd.
