EX-SITU CONSERVATION OF FLORA SULAWESI IN INDONESIAN BOTANIC GARDENS

Indonesian Botanic Gardens (IBGs) consist of forty-three gardens which represent distinct characteristic of Indonesian ecoregions. Thousands living collection native to Sulawesi are exist at IBGs. This study aims to reveal the Sulawesi's collections in IBGs and compared to vascular plants species across the island. The conservation status of those collections are also uncovered. Plant collections data are obtained from seven IBGs, namely Bogor Botanic Garden (BG), Purwodadi BG, Bali BG, Enrekang BG, Kendari BG, Parepare BG, and Pucak BG. A number of 1,561 species originated from Sulawesi (243% of total Sulawesi 'species) are cultivated within seven IBGs. 1,477 species of which are angiosperms (27,7% of total Sulawesi's angiosperms), 67 species pteridophytes (12,1% of total Sulawesi's pteridophytes), and 17 species gymnosperms (34% of total Sulawesi's gymnosperms). Orchidaceae is the greatest angiosperms with 522 species. Dryopteridaceae and Polypodiaceae are the largest pteridophytes with eight species each. Podocarpaceae is the highest gymnosperms with five species. A quantity of 23 species of Sulawesi's collections is threatened with global extinction. Nine species of which already listed in IUCN red list as threatened plants of Sulawesi.
