Plant transpiration is the key to restore the water balance of mining site. Plant transpiration will relate to water loss rate from the land, therefore the transpiration ability of plants can be used as one criterion on the selection of tree species for postmining land reclamation program. This research aimed to compare transpiration capability among selected tree species and to compare potential loss of water through transpiration and the rate of water input through rainfall. Seven native lowland rainforest species commonly found in the Bangka Belitung Islands were used in this research. We measured parameters affecting transpiration rates, i.e. stomatal conductance, leaf area index (LAI), and subsequently calculated canopy conductance and transpiration rates. The calculated transpiration rate of each species was Shorea leprosula (4.47 mm/day), Hopea odorata (3.93 mm/day), Aquilaria malaccensis (3.34 mm/day), Shorea javanica (2.59 mm/day), Terminalia catappa (2.01 mm/day), Flacourtia rukam (1.96 mm/day), and Eusideroxylon zwageri (1.35 mm/day). During the driest month, Shorea leprosula would have the highest potential of water loss through transpiration than that in other studied species.
