Pangolin (Manis javanica, Desmarest 1822) has believed by many peoples as food and medicine who have a high economic value, so demand of pangolin tend increase. Wild harvesting from natural habitat are the way always used to supply of demand, and this was affecting to wild population has been decrease significantly. Captive breeding programs in the ex situ area is the best alternative solution to support the demand sustainability and its conservastion in natural habitat. The question is, “ did success possibilities to captive breeding? Based on the study have been done about animal behaviour and implementation of some technical of captive breeding program,we would like to say that the captive breeing program of pangolin could be success. Key words: pangolin, behaviour, daily activities, captive breeding

A vegetation survey of Sumatran orangutan habitat was carried out as part of a larger orangutan conservation project in Batang Toru forest during October 2007–January 2008. The purpose was to provide information about the forest structure and composition including orangutan feeding and nesting trees based on 3.84 ha total cumulative area sampling in 11 sites. The results of the inventory of trees with diameter at breast height (DBH) of 96 plots 20x20 m size e” 10 cm in 3.84 ha area sampling show Roland H. Simorangkir; Sri Supraptini Mansjoer; M. Bismark

A vegetation survey of Sumatran orangutan habitat was carried out as part of a larger orangutan conservation project in Batang Toru forest during October 2007–January 2008. The purpose was to provide information about the forest structure and composition including orangutan feeding and nesting trees based on 3.84 ha total cumulative area sampling in 11 sites. The results of the inventory of trees with diameter at breast height (DBH) of 96 plots 20x20 m size e” 10 cm in 3.84 ha area sampling showed that 274 trees species in 56 families, represented by 1,896 trees with a total basal area of 148.9 m2/ha and density of 494 trees/ha, totally the forest habitat dominated by Sapotaceae, Fagaceae, Dipterocarpaceae, Myrtaceae, Anacardiaceae, Casuarinaceae, Podocarpaceae, Lauraceae, Euphorbiaceae, and Theaceae. The forest structure and composition were dominated by trees with diameters of 10-30 cm (75.6% of total inventoried trees) and heights of 10-30 m (80.4%). There were 96 orangutan feeding trees species in 25 families, represented by 536 trees with total basal area of 46.7 m2/ha. The most prominent feeding trees species were Madhuca sp. (local name: sapot), Lithocarpus conocarpa (hoteng), Castanopsis sp. (andihit), Podocarpus imbricatus (sampinur bunga), Litsea firma (urat tiga), Ganua motleyana (sapot), and Garcinia bancana (hole tanduk). The feeding trees with diameters 10-30 cm (77.4% of total identified feeding trees) and heights 10-30 m (78.5%) distributed abundantly in Batang Toru forest, especially in the old moist secondary forests. Key words: Sumatran orangutan, habitat, vegetation survey, Batang Toru forest

Ungko/mountain agile gibbon (Hylobates agilis) is one of Sumatera endemic gibbon and is considered a near threatened spesies. The aim of this research was to study the population and habitat of mountain agile gibbon (ungko) at Batang Gadis National Park. Surveyed on population of ungko and habitat condition were conducted three-months period (July-September 2005). Methods used were line transect for population estimation and ungko habitat was analysed by block line method. The average group size density for ungko at the study area was 2.60 groups/km2, group size was estimated at 3.41 animals, and the population density was estimated 8.82 individuals/km2. There were 2,240 groups, and 7,620 individuals in Batang Gadis National Park. The vegetations were dominated by Geunsia farinosa, Mallotus sp. and Litsea elliptica. Food sources for the ungko were dominated by Geunsia farinosa, Craton laevifolius, Myristica iners and Syzygium sp. Keywords: ungko (Hylobates agilis), population, habitat

The agile gibbons (Hylobates agilis) was considered as endangered species. The information on population status of the agile gibbons are limited and fluctuative. The overall aim of this project was to generate critical baseline data on the status of agile gibbon and its distribution at Batang Gadis National Park, North Sumatera. The survey had been conducted at three different locations during August 2006 up to January 2007. Locations of the research were based on types of forests: undisturbed (primary forest) and disturbed forest (logged-over forest and post-cultivated forest). Population density of agile gibbons were conducted by fixed-point count and line transect method. The average population density for agile gibbons at post-cultivated forest was 15.5 individuals/km2, logged-over forest was 13.2 individu/km2 and primary forest was 9.9 individu/km2. While, group density for agile gibbon at post-cultivated forest was estimated at 4.7 group/km2, logged-over forest was 4.0 group/km2 dan lower at primary forest was 3.3 group/km2. There were 3,292 groups and 10,620 individuals in Batang Gadis National Park. On location research Aek Nangali Village, agile gibbons were found at 600-955 m asl but based on preliminary research on July-August 2005, agile gibbon was found at 300-1.200 m asl from north to south of Batang Gadis National Park. Keywords: Hylobates agilis, Batang Gadis National Park, population density dan group density
