After Meijer had conducted ecological study on Mt. Gede Pangrango in 1959, the subsequent study did not monitor its d inamics. This study aimed to compare current vegetation composition and tree structure with past 50 years data based on Meijer publication. One hectare permanent plot reconstructed at submontane zone to identi fy vegetation changes during 50 years on August 2009. Vegetation analyses method was similar with 50 years ago include field tree identification, diameter at breast height (dbh), tree height, and first branch height. Result showed the species richness decreased from 233 to 166 species, diversity index (H) slightly changed from 3.39 to 3.29, and similarity index indicated the differentiation of both tree communities was 51%. Further r nore, from 63 tree species presented in 2009, 47 species was similar with 50 years ago and 16 species know n as new record. Moreover, 18 tree species recorded in 1959 had lost in 2009 i.e., Ehretia javanica, Heli( 7ia javanica, Mischocarpus frutescens, Saurauia bracteosa, Wedlandia glabrata, etc. The highest abundance oi I both studies was Villebrunea rubescens. The changes of vegetation composition and tree structure may have been caused by (1) wind disaster occurred on 1984; (2) human pressured from the nearest village; and (3 ) natural forest regeneration towards climax condition.

GRADSTEIN, R. et al. 2010. Bryophytes of Mount Patuha, West Java, Indonesia. Reinwardtia 13(2): 107-123. - This paper presents the results of a two-day survey of the bryophyte flora of Mt. Patuha and its surroundings near Bandung, West Java, carried out in the framework of the 5th regional training course on bryophyte and lichen diversity and conservation organized by SEAMEO BIOTROP, Bogor, in July 2009. A total of 159 bryophyte species were identified, including 98 mosses, 60 liverworts, and 1 hornwort, representing almost 1/6 of the total bryophyte flora of Java. Three moss species, Bryohumbertia subcomosa (Dix.) J.-P. Frahm, Fissidens gymnogynus Besch. and F. polypodioides Hedw., and one liverwort, Lejeunea pectinella Mizut., are new additions to the Javanese flora. The bryophyte diversity of Mt. Patuha is well representative of the Malesian flora and is rich in uncommon species. However, the relatively poor representation of shade epiphytes and commonness of sun epiphytes and generalists reflect disturbance of the forest by anthropogenic activities. Careful attention should be given to conservation of the remaining natural forest in order to prevent further losses of the rich bryophyte diversity of the area.

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.

The role of botanic garden in spread of non-native plant species has concerned of international worldwide. This study aimed to study the extent of non-native plant species from Cibodas Botanical Garden (CBG) which invades into natural rainforest. A line transect was made edge-to-interior with 1,600 m in distance from CBG boundary. Result showed that distance from CBG was not significant in correlation with non-native tree and treelet density. Furthermore, presence of existing CBGs plant collection was not a single aspect which influenced presence and abundance. Three invasive species possibly was escape from CBG and it showed edge-to-interior in stems density, i.e. Cinchona pubescens, Calliandra calothyrsus and Cestrum aurantiacum. The patterns of non-native species were influenced by presence of ditch across transect, existence of human trail, and the other non-native species 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.

Botanical exploration at Mt. Galunggung protected forest, West Java was conducted in June 2014. This study was aimed to collect plant living specimen for ex-situ conservation purpose of Kuningan Botanic Garden and to conduct vegetation analysis in crater area. Random inventory method at 600-1200 m asl was used to collect plant in that area. Vegetation analysis of tree, shrub and herb were used line transect methods. Result showed that 273 collection numbers of plant living species were collected from Mt. Galunggung, which consisted of 213 species, 143 genus and 72 families. Plant families which most collected were Moraceae, Euphorbiaceae, Arecaceae and Lauraceae respectively. In crater area was collected a lot of pioneer plant, such as dawola (Trema cannabina Lour.), paku tiang (Cyathea spp.), nangsi (Villebrunea rubescens (Blume) Blume), muncang cina (Ostodes paniculata Blume), mara (Macaranga tanarius (L.) Mull.Arg.), and kareumbi (Homalanthus populneus (Geiseler) Pax). Furthermore, in secondary remnant forest were collected typical plants of Java mountains such as saninten (Castanopsis argentea (Blume) A.DC., puspa (Schima wallichii Choisy) and some of tree seedlings from Lauraceae family. Vegetation affected by eruption in Mt. Galunggung is in early stage of forest succession and still develops to next stage of succession. Tree, shrub and herb in the crater area were dominated by Cyathea contaminans (Wall. Ex Hook.) Copel., Calliandra callothyrsus Meisn. and Ageratina riparia (Regel) R.M.King & H.Rob. with Hâ€™ was 0.35, 0.31 and 0.30 respectively.
