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 14th 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.

Abstract

Indonesia possesses 386 plant species that are categorized as threatened. Dipterocarpaceae contributes the largest number, reaching 36.79 % of the total threatened plant species, followed by Myristicaceae (13.73 %) and Nepenthaceae (6.99%). Of these 386 threatened species, 29.27 % are critically endangered, 17.88% are endangered, and 52.85 % are vulnerable. Bogor Botanic Garden recently maintains 68 threathened plant species if Orchidaceae and Nepenthaceae members are not included on the list. Two species have been regarded as extinct, namely Dipterocarpus cinereus and Calamus spectabilis, while two other species are regarded as extinct in the wild (Mangifera casturi, and Mangifera rubropetala). This information can be useful for everyone for different purposes, especially for those who concern in the conservation of threatened plant species in Indonesia.

Abstract

A molecular analysis was conducted to determine whether Eugenia boerlagei Merr. (Myrtaceae) belongs to genus Eugenia or Syzygium based on sequences of cpDNA fragments namely atpB-rbcL intergenic spacer. The study used seven specimens of Syzygium sect. Jambosa, three of Syzygium sect. Syzygium, two of Eugenia s.s. and one of Eugenia boerlagei Merr. with Baeckea ovalifolia and B. tuberculata as the outgroup. The results show that Eugenia boerlagei is appropriately placed under the genus Syzygium.

Abstract

Food insecurity has been reported to be the top most concern in East Nusa Tenggara (Timor Island) compared to that in other provinces in Indonesia. The use of local species as food sources is one possible arm in the fight against food insecurity. Gewang (Corypha utan Lam.) is a palm species which produces starch similar to the true sago palm (Metroxylon sagu). Although it is important to promote the species as a starch crop, information on its current population and seedling growth performance is still lacking. Hence, a one-hectare plot was surveyed and an experimental plot was established for population and regeneration analyses. In the 1 ha plot there were 31 productive trees, 2 post productive trees, 63 immature trees and 2,211 seedlings. The dispersion of the species followed the clumped pattern for immature trees and seedlings, but shifted to random pattern at maturity or productive stage. The seedling survival was stable when weeded, but dropped to 50% when un-weeded. However, in spite of its stem extraction for starch consumption, the population of C. utan in East Nusa Tenggara was stable. This indicated that C. utan in East Nusa Tenggara is a potential alternative food source to help build food security in Indonesia especially in dry lands like Timor Island and its adjacent regions.
