Abstract: To learn about the abandoned mined area tree diversity, aboveground biomass and carbon stock a study was conducted in quartz mined Bilikal hillock area which is geographically adjacent to Umbalebylu 8 km to Bhadra wildlife sanctuary and 10 km of Kuvempu University. In the present study 0.14ha (350 m×4m) transect, we recorded 1527 individuals comprising 22 families among them Papilionaceae with 6 genera and 7 species, Combretaceae with 2 genera and 4 species followed by Rubiaceae with 3 genera and 3 species and Apocynaceae with 2 genera and 3 species. Based on girth class assessment nearly 1564 individuals comprising 1-10 cm had 559 individuals, the basal area was more within the girth class of 40-50 cm. But aboveground biomass and carbon stock were highest within the girth class of 20-30 cm. varying with species structure and girth class were a disturbed forest patch, the species composition needs management and restoration to retain the biodiversity intact to provide a niche for other co-species.
