Purnomo DW, Helmanto H, Yudaputra A. 2015. Role of Indonesian Botanic Gardens in plant conservation and carbon emission reduction. Pros Sem Nas Masy Biodiv Indon 1 (1): 66-70. National biodiversity management will only be effective if its potential exploration is parallel with sustainable conservation efforts. Land status of botanic gardens (BG) which should be permanent and can not be converted into other uses, is securing the conservation of the plants in the gardens. This study aims to investigate vegetation cover potential of the Indonesian Botanic Gardens (IBG) as a synergy model between plant conservation and use with the government cross-cutting programs to reduce carbon emissions. The role of IBG’s collection has been examined by Purnomo et al. (2013), in which 24% of the Indonesian threatened plants have been collected in 25 BGs. Carbon stocks of BG’s vegetation cover can be measured using rapid estimation method by calculating the covered area multiplied by the carbon content of each cover type. Based on the provisions of Masripatin et al. (2010), total C stock in IBG’s vegetation cover is 336,058.62 tonC. BGs having a vast area with dense vegetation cover, i.e. Jambi BG and Balikpapan BG, deposit the highest C stock value of 47293.45 tonC and 41033.96 tonC respectively. Old BG collections, represented by 4 BGs of Indonesian Institute of Sciences, have an average C stock of 138.32 tonC/ha, whereas more recently-developed BGs, represented by Batam BG, Kendari BG, Banua BG, and Sriwijaya BG have an average C stock of 45.71 tonC/ha. The carbon content of ideal vegetation cover in BG is 105.81 tonC/ha.
