Abstract
This study aims to develop seed capsules with pioneer tree species with fire and drought resistant for forest restoration by using an Unmanned Aerial Vehicle (UAV) instead of planting tree by forest workers. The appropriate species were selected including Peltophorum dasyrachis (Miq.) Kurz, Dalbergia cochinchinensis Pierre, Phyllanthus emblica L., Pterocarpus macrocarpus Kurz, and Albizia procera (Roxb.) Benth. Seed capsule were divided to 5 categories, i.e. (1) chemical fertilizer, (2) mycorrhiza, (3) chemical fertilizer + mycorrhiza, (4) seed in bentonite capsule, and (5) bare seed. The results showed that the most suitable species in both abandoned maize field and forest canopy gap are Albizia procera (Roxb.) Benth, Dalbergia cochinchinensis Pierre, and Pterocarpus macrocarpus Kurz. with the highest germination and survival rate. These species have the ability to fix atmospheric nitrogen through symbiosis with bacteria or fungi in root nodules. The small seed size is appropriate for using in seed capsule with composed of Bentonite clay. Mycorrhiza is the most suitable composite to combine to the seed capsule for promoting seedling growth rate by promoting the growth of root. However, the success of forest restoration program is not only the germinating of seedling from capsule but it needs more concern of other threats e.g. forest fire, long period of drought or seed destroying by animals to get achievement.
Keywords: seed capsule; forest restoration; unmanned aerial vehicle (UAV)
