ABSTRACTHabitat Reconstruction of Bali Starling Leucopsar rothschildi Stresemann 1912 in WesternPart of Bali Island. Bali Starling Leucopsar rothschildi Stresemann 1912 is an endemic speciesof north western part of lowland of Bali Island. The land use changes of original habitat BaliStraling to resettlement and agriculture area since the year 1980, has caused this speciesmoved to the marginal habitat in the Prapatagung Peninsula and resided in Telukkelor areas. Inwet season this bird in Prapatagung Peninsula can have enough food from vegetation in themonsoon forest in Telukkelor, but in dry season the birds must look for the food in evergreenforest near Prapatagung. At the end of 2005, this species was categorized as an extinct speciesin the wild, but population in captured are still abundant. In 2007 and 2008, the release of thisbird in the nature has been done in Prapatagung peninsula area. In following year birdmonitoring showed that some pairs of these birds can breed sucessfully.The development of Bali province has caused the end of adding more the electrical powersupply from Java electrical power system. To transmite the electrical power to Bali, extra highvoltage electrical power transmission infrastructure (SUTET) that will be passing and cuttingthe lowland forest ecosystem in Prapatagung Peninsula is needed. Other infrastructures suchas JawaâBali bridge and high way were under studied to develop in similar area. Theinfrastructures were assumed will decrease the carrying capacity of evergreen forest insupporting Bali Starling food especially during dry season. Based on the recent condition,study on the habitat recovery of Bali Starling should was conducted especially on the originalhabitat that already changed. The results showed that local state land tenure of Sumberklampok,Sumberbatok, Tegalmuara and Tanjunggelap as in the past known as Bali Starling habitatshould be returned back their function as home of Bali Starling. To support this action plantinventarisation has been conducted to understand the rest of plant diversity in supportingBali Starling conservation.Key words: Bali starling, Leucopsar rothschildi, reconstruction, habitat.

ABSTRACTLand Use Model of Moti Island, Ternate, Moluccas: A Vegetation Based Spatial Design Analysis.The Moti Island was dominated by mountain areas and humitropepts soil type which havehigh organic matter and low subsoil base saturated values. Geologically, it is a volcanic rockwith andesite composition includes lava, breccias and tuffs volcanic. Combined with highrainfall, width of island (24.6 km2) and very steep mountain (950 m asl.) the island has becomefragile when not well managed. Compared to the other district, the productivity of this area waslow because the natural resources have not been well developed yet. The shortage ofbiodiversity data of Moti Island has become major obstacles in developing Moti Island. Thisresearch was conducted to develop land use models as basic knowledge for spatial designanalyses of Moti Island. Detail discussion on developing Digital Elevation Model of land useand slope area based on vegetation data was presented in this paper.Key words: Moti, land use, digital elevation model (DEM), spatial designing analyses

ABSTRACTVegetation structure and composition of Bali Starling (Leucopsar rothschildi Stresemann,1912) Habitat at Labuan Lalang monsoon forest, Bali Barat National Park. Research wasconducted in Labuan Lalang monsoon forest, Bali Barat National Park in May 2010 to identifytheir vegetation structure and composition of plant species communities in this area. Thisinformation was important as basic data for developing model for habitat reconstruction ofendemic Bali starling birds (Leucopsar rothschildi Stresemann 1912). Several ecologicalparameters information such as name species, frequency, density and abundance of individualspecies were collected for qualitative an quantitative analyses.The result showed that 93 species belonging 84 genera and 37 families were found in this area.Some plant species were recorded as endangered such as Strycnos lingustrina, Helicteresixora, Protium javanicum, Rauvolfia serpentina, Zanthoxylum rhetza, Ziziphus rotundifolia,Ceriops tagal, Flacourtia indica, and Santalum album. The important species that composedin this forest were dominated by Grewia ericocarpa , Schoutennia ovata (Tiliaceae) andfollowed by Vitex trifoliata and Abutilon indicum. The species diversity and evenness indexof Shannon-Wiener indicated that species diversity in this forest were not too high and thepopulations on unstable condition. Principal Coordinat Analyses (PCO) on the tree height andaltitude data of every tress showed that tree species associated to Bali starling were found onthe 10 â 25 m tree hiehgt community and occupied in the area of 40 â 60 m asl. The problems andreal condition of the area as the habitat of Bali starling were discussed in this paper.Key words: vegetation, species diversity, Bali starling, Bali Barat National Park

Pangumbahan coastal area is one of many important nesting sites of the green turtle (Chelonia mydas Linnaeus) in Indonesia. This area is mainly comprises of disturb coastal old secondary forest. Some sites along the seashore were converted into fishpond, dry land agricultural and other was destroyed for other uses or as an open unproductive areas. However this area has a still plays an important role especially for the conservation of green turtle habitat and also for the ecosystem stabilization of the coastal area in general. Floristic research was conducted on September 2009 to investigate the existing vegetation structure and composition along the seashore using transects method.The Ã¢â¬Åpoint center quarters methodÃ¢â¬Â was used to calculate the importance value of the vegetation on every turtle nesting sites. The important natural species vegetation communities in the area were comprises of herbs, shrubs and trees species. Ipoemoea pes-caprae (L.) R. Br and Spinifex littoreus (N. L. Burman) Merrill as a first layer coastal line plant community that play as an important herbs species which creeping grown on the white sands coastal surface. The second layer comprises herbs, small trees and shrubs such as Pandanus tectorius Parkinson ex Zucc, Crinum asiaticum L. and Callotropis gigantea R.Br. The second layer species plays as a vegetation community which covering and protecting the green turtle nest site from the direct sunshine, running of big wave and heavy rain water. Terminalia catappa L., Calophyllum inophyllum L., Barringtonia asiatica (L.) Kurz. and Hibiscus tiliaceus L. as a big crown tree community grown covering on the most behind as a back layer of coastal line which play as shading trees of the second layer species community, especially to stabilized humidity and temperature of the sand and the environment. The vegetation structure and composition of the old secondary coastal forest of Pangumbahan was described to understand the detail role and function of the vegetation species in this area.

A spatial analysis was applied to predict the natural distribution of agarwood producing taxa of Aquilaria and Gyrinops in Indonesia.This research was conducted using herbarium materials which deposited in Hebarium Bogoriense, Research Center for Biology-LIPI and field data collected by researcher within periods of 1992-2009. Time serial maps of 1:250.000 were used in this analysis such as Indonesia digital base map of 1990, province land cover and deforestation digital maps of 1989 and 2005.Every sites of herbarium collection was identified using digital Cyclopedia of Malesian Collectors for the name of village/place and date of collection. The coordinate of those sites comprises latitude, longitude and altitude was retrieved by query method using Indonesia digital geo-reference data. Tabulated data of every collection/data was created and then overlaid to the time serial land cover and deforestation maps using GIS software, to identify the recent condition of that area. The results show that horizontal natural distribution of Aquilaria was mainly occur in the western part of Indonesia, while Gyrinops in eastern part of Indonesia. Vertical distribution analyses of the Aquilaria and Gyrinops showed that in general both genera are mainly grown naturally in the low land areas less than 300 m asl. Spatial analyses using time serial land cover and deforestation maps indicated that low land areas less than 300 m asl. having very high risk on the land use changes, whereas increasing land status classification from six on 1989 to fifteen on 2005. More than 20 % of forested areas have been change into non forest area such as plantation, agricultural land, resettlements and open unproductive lands since 1989. Natural distribution of agarwood producing taxa horizontally and vertically on all of major islands and the conservation strategy were discussed in this paper.

Based on the distribution data of 13 species of Curcuma found in Java,spatial analyses using land status and land used thematic maps has been earned out.The purpose of this analysis is to detenvine thehabittat that usually Curcuma grows both cultivated or wild.Cluster analysis based on distance Eucledian using Statistical Program for Social Sciences(SPSS) for Window Release 6 software was administered to classify the relation between Curcuma species and their habitat.The result showed that Curcuma domestica; C. aurantiaca, C. aeruginosa, C. zedoaria, C. xanthorhiza and C.viridifolia are wide distributed in Java, but C. mangga, C. heyneana, C. purpuracens, C. soloensis, C. euchroma, C.colorata and C. borg are strickly found in specific areas only. Eventhough C. phaeocaulis, C. sylvatica and C. ochrorhiza has been reported found in Java, that species should be monitor due to limited information of this species in Java.Spatial analyses using ArcView software showed that Curcuma found in the 13 kinds of land status and land used.Curcuma mainly occupies in the habitat that classify as a "daratan" status withlanduse status as resettlement.Beside that Curcuma are also grown in the teak forest areas, but some of them have been changed to secondary forest after the timber harvested proven by landuse thematic map.Those areas are classified as a high-risk habitat due to probability status can be changed easily.Cluster diagram analyses using land status thematic maps, showed that there are some habitat similarities among C. xanthorrhiza and C. zedoaria, and then among C. aeruginosa, C. aurantiaca, C. viridiflora and also among C. borg, C. soloensis, C. mangga, C. heyneana, C. colorata, C. euchroma and C. purpuracens. Cluster diagram analysis using land use thematic showed that maps some similarities habitat also occurred betweenC. aurantiaca and C.aeruginosa, and then between C. zedoaria, C. xanthorhiza and C. viridifolia, and also between C. mangga, C. heyneana,C. purpuracens, C. soloensis, C. euchroma, C. colorata and C. borg.
