Due to contribution of Target 8 of the Global Strategy for Plant Conservation GSPC Botanic Gardens, Cibodas Seed Bank committed to increase its ex situ plant collection through seed banking. This research aimed to assess population and collect seeds from Cibodas remnant forests and its neighboring, Mt. Gede Pangrango National Park forest, for seed banking purpose. Thirty-two numbers of seeds belonging to fifteen families were collected. Two species were included in IUCN red list i.e. Saurauia cauliflora (vulnerable) and Magnolia blumei (least concern) and one species classified as endangered species by World Conservation Monitoring Unit (WCMC) i.e. Pinanga javana. Sixty-five percent population were possible to collect without affecting the availability of the seeds in the nature. Around a half of seeds were collected at natural dispersal stage to ensure the seed maturity. Ninety-one percent collected seeds were expected as orthodox seeds that can be stored in Cibodas Seed Bank and three species were recalcitrant and cannot be stored in Cibodas Seed Bank i.e. Calamus ciliaris, C. reinwardtii and Daemonorops rubra. Cut-test results showed 78% seed collected were full seeds, that were not infested, empty or immature seeds. This study provides information regarding the readiness of population for seed collection and species were collected and stored in Cibodas Seed Bank.

One of the botanic gardens businesses is socializing cultivated plants from the garden to be further utilized, especially for reforestation (and other conservation purposes), research and educational purposes. This socialization can be conducted through seeds exchange and plant (and parts) that transferred for various users. Cibodas Botanic Gardens (CBG), as one of the Indonesian botanic gardens, is also conducted this activity. Plant materials and so the data needed for these purposes are recorded in the material(s) transfer agreement (MTA). The study aimed to analyze the number, type, and species of transferred plant materials and the data, the background of the applicants and for what purpose of the materials is needed based on MTA’s documents. This study conducted through a quantitative descriptive method based on the materials transferred from 2013 to 2018. The results described that, for six years, the number of MTA was 86 documents, with 81 applicants. The applicants from local were 92.6% and foreign such as from China, Netherlands and Japan were 7.4%. For six last years, the transferred materials included 1,205 in the form of living plants, 201 specimens in form of herbarium, 8,605 specimens in the form of seeds, many thousands various unit of part of plant, plant propagation unit and other plant materials (i.e. mycorrhiza, fungi/ lichen/ moss, rhizoid and thallus, and ascoma), and 63 unit in the form of data and other information. The results expected to be able to describe the contribution range of CBG, especially in ex-situ plant conservation and the data, both on the local and international scale.Keywords: plant materials; material(s) transfer agreement (MTA); ex-situ plant conservation; Cibodas Botanic Gardens (CBG)

Dipterocarpaceae are globally important tree family due to its conservation status. Most of Dipterocarpaceae in Java are distributed in lowland area. However, several species exist in higher altitude such as Gede Pangrango National Park (GPNP) area. All Dipterocarpaceae species in GPNP are vulnerable or endangered based on IUCN Red List status. Dipterocarpaceae species are main priorities for plant conservation in GPNP. In this study we conducted early survey of Dipterocarpus retusus Bl. sub-population in Bodogol area (northwest slope of GPNP) at elevation 800-1000 m above sea level. We searched D. retusus individuals along trail in the Bodogol area from forest exterior towards forest interior. The subpopulation of D. retusus detected in mixed forests that dominated by emergent Fagaceae species (Castanopsis argentea). Positive correlation between diameter and height may reflect low disturbance rate in Bodogol forest area. We also found negative effect of habitat elevation toward plant height, which mean that the centre of sub-population located in the lower elevation part of the sampling location. This study signifies the importance of Bodogol forest area that contain globally important Red List plant species.
