TL;DR: In this paper, the authors presented the Indonesian Botanic Gardens' achievements in implementing Target 8 of the Global Strategy for Plant Conservation (GSPC), which highlights the importance of ex situ collections of threatened plants and their recovery program.
Abstract: Target 8 of the Global Strategy for Plant Conservation (GSPC) has a very close link to the works of botanic gardens. It highlights the importance of ex situ collections of threatened plants and their recovery programme. The aim of this paper was to present the Indonesian Botanic Gardens' achievements in implementing Target 8 of the GSPC. It is shown that to date 21.5% of Indonesian threatened plants have already been collected ex situ in Indonesian Botanic Gardens. The reintroduction programme was also initiated. In its 14 th meeting this year, SBSTTA recommended proposal for an updated GSPC (for 2011-2020), in which the Target 8 was changed to "At least 75 per cent of threatened plant species in ex situ collections" (from formerly 60 per cent). Thus, further work is still needed to increase these achievements.

TL;DR: In the authors' opinion, the existence of S. liukiuensis will be sustainable, since the natural population of the species in Ishigaki Island was established as protected areas and managed by Satake Corporation and also the corporation announced and built `The Toshihiko Satake Memorial Palm Museum` in natural locality sites of thespecies.
Abstract: Genetic diversity of Satakentia liukiuensis in some cultivated individuals in Bogor Botanical Garden (Indonesia) and Nong Nooch Tropical Garden (Thailand) compared with natural population was analyzed by RAPD markers. Satakentia liukiuensis is a monotypic genus and an endemic palm species in Japan and it distributed in very restricted area in Ishigaki Island and Iriomote Island in Yaeyama Group of the Ryukyu Islands. The ten of RAPD primers (Operon Tech. Inc.) were used in RAPD analysis generated 82 amplifi ed bands, which is 27 bands (32.9%) were polymorphic. A phenogram generated by UPGMA clustering analysis shows all accessions from natural population were separated from cultivated individuals with genetic distance 0.104. Genetic variation among accessions in natural population was lower than cultivated individuals. The genetic uniformity of S. liukiuensis in natural population may due to the result of the inbred nature of its small population size for a long time. In our opinion, the existence of S. liukiuensis will be sustainable, since the natural population of the species in Ishigaki Island was established as protected areas and managed by Satake Corporation and also the corporation announced and built `The Toshihiko Satake Memorial Palm Museum` in natural locality sites of the species. RAPD method is a very fast way of obtaining genetic information and the methods require no prior knowledge of the DNA sequence to generate genetic markers.
