Mutaqien Z, Zuhri M (2011) Establishing a long-term permanent plot in remnant forest of Cibodas Botanic Garden,. Cibodas Botanic Garden (CBG) has unique characters; almost 10% of which is forested area adjacent to the natural forest of Mt. Gede Pangrango National Park. The area is a transition between natural forest and artificial habitat which mostly consists of exotic plant species. The permanent plot in CBG was established in [2007][2008][2009]. Two hundred and eighty four units of 10x10 square meters sub-plot were established in four locations, i.e. Wornojiwo, Kompos, Jalan Akar, and Lumut forest. Vegetation analyses were conducted for trees, saplings, shrubs, and herb species. The inventory found 137 species plants consisting of 74 tree species dominated by Villebrunea rubescens (Bl.) Bl. and Ostodes paniculata Bl., 30 shrub species dominated by Strobilanthes hamiltoniana (Steud.), 24 herb species dominated by Cyrtandra picta Bl., 6 fern species mainly consisted of Diplazium pallidum Moore, and 3 climber species dominated by Calamus reinwardtii Mart. In comparison with the natural forest of Mt. Gede Pangrango National Park, the CBG permanent plot showed a good representative of the vegetation of lower montane forest. A regular monitoring during the successive years is needed to maintain diversity, monitor forest dynamics and anticipate the spread of invasive plant from CBG.

The role of botanic garden in spread of invasive alien plant species has concerned of international worldwide. The aim of this research was to study the extent to which non-native plant species from Cibodas Botanical Garden (CBG) invades into natural rainforest of Mt. Gede Pangrango National Park that adjacent CBG. A line transect was made edge-to-interior with 1600 m in distance from CBG boundary. Result showed that distance from CBG was not significant in correlation with tree and treelet non-native density. Furthermore, presence of existing CBG's plant collection irregularly responsible for spread of non-native species into natural forest. Three invasive species (Cinchona pubescens, Calliandra calothyrsus, and Cestrum aurantiacum) possibly were escape from CBG and it showed edge-tointerior in stems density. The patterns of other species were influenced by presence of ditch across transect (Brugmansia candida and Solanum torvum), transect location along human trail which facilitate Austroeupatorium inulifolium spread into interior forest, and another non-native species (Solanum macranthum and Toona sinensis) did not have general pattern of spread distribution. Overall, botanical gardens should minimize the risk of unintentional introduced plant by perform site-specific risk assessment.

Cibodas Botanic Garden area is adjacent with natural forest of Mt. Gede Pangrango National Park which consequences both vegetation in the border area are influence each other. The aims of this research were to study plant vegetation of forest area adjacent to Cibodas Botanical Garden and compare it with forest interior using transect method. The results showed that species richness in forest interior were higher than adjacent forest area. Furthermore, number of tree species, basal area and Shannon-Wienner diversity index in forest boundaries were higher rather than forest interior. Habitats along the forest edge were inhabited by trees with large dbh and low tree density. While trees inhibited forest interior areas with high density but small in size. The trees in forest interior were dominated by Schima wallichii, Lithocarpus pallidus and Turpinia sphaerocarpa. While trees in the forest boundary vegetation were dominated by Engelhardtia spicata, Litsea firma and Lithocarpus indutus. The tree age structure of forest interior and forest edge showed an inverted J-pattern and flat pattern respectively. Meanwhile, tree communities on edge forest vegetation showed similar age structure, especially in middle diameter class.

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.
