Abstract. Danarto SA, Yulistyarini T. 2019. Selection of lowland plants with high potention of carbon stock for rehabilitation of degraded lands. Pros Sem Nas Masy Biodiv Indon 5: 33-37. Degradation of forest areas in Indonesia is feared to increase greenhouse gas emissions which have an impact on global warming. Research on estimating carbon stocks of dry lowland plants was carried out at Purwodadi Botanical Garden in August 2013 using 99 species of local plants collection of Purwodadi-LIPI Botanical Gardens. Biomass measurement uses stem diameter data at breast height and its calculated with allometric model using Kettering method. The value of carbon stock is determined using the formula of 46% of the total value of plant biomass. The results showed that there were 10 types of local plants with high-medium carbon stock potential i.e, Schleichera oleosa (225.29 kg C yearˉ1), Michelia alba (88.56 kg C yearˉ1), Parkia timoriana (61.62 kg C yearˉ1), Pterocarpus indicus (53.70 kg C yearˉ1), Dysoxylum gaudichaudianum (53.19 kg C yearˉ1), Madhuca longifolia (51.77 kg C yearˉ1), Peltophorum pterocarpum (51.52 kg C yearˉ1), Spondias malayana (51.11 kg C yearˉ1), Artocarpus altilis (47.77 kg C yearˉ1), and Alstonia scholaris (45.08 kg C yearˉ1). The conclusion from the results of this study is that species of selected local plants with high potential in carbon sequestration can be recommended for revegetation of degraded dry lowland areas.
