PublicationNKK Lab-Research Introduction

My name is Heri Suheri. I am a Master's student in Graduate School for International Development and Cooperation (IDEC), Hiroshima University. My research is focused on conservation management, which title is “Wildlife’s habitat corridor for sustainable conservation management in Gunung Gede Pangrango National Park, Cibodas Biosphere Reserve, West Java, Indonesia”. This research is supervised by Prof. Nobukazu Nakagoshi, Assoc. Prof. Kensuke Kawamura and Assoc. Prof. Osamu Higashi.

This study consists of Gunung Gede Pangrango National Park (GGPNP) as a core zone of Cibodas Biosphere Reserve, which the wildlife habitat fragmentation has occurred due to human activities. The impact of various human activities and growing population density in the settlements surrounding area, caused this park is under significant pressure.
In the several locations showed habitat fragmentation due to tourism activity, encroaching and illegal hunting (Iskandar 2008). These activities not only reduce the area, but also affect the structure to the movement of wildlife species (Forman 1995). The Effects of habitat fragmentation on wildlife include the loss of species in shatters, changes to the composition and ecological developments of animals (Bennet in IUCN 2003). Therefore, it is need effort to save wildlife habitat and protecting them from extinction.
Habitat fragmentation can be reduced by maintaining landscape connectivity. Making corridors are significant effort to maintenance of landscape connectivity, which facilitate as alternative habitat and movement of migratory fauna and help in maintaining the territory (Kharel et al. 2002). The corridors connect of wildlife habitat fragmentation and there are essential elements for conservation management (Chetkiewicz and Boyce 2009), reduce the loss of biodiversity and support scatter and genetic exchange among isolated populations (Doko et al. 2010).
The most important requirement for maintenance corridor is the identification of suitable habitats (Manly et al. 2002; Guthlin et al. 2011) and habitat protection for a given wild species as well as space, food and water (Xiaofeng L. 2010).
As a natural system, the GGPNP is very essential for human life, because human and natural systems are integrated system. This park also has a high biodiversity in flora and fauna. The endangered mammal is conserved in this park, which include the Javan langur (Trachypithecus auratus), Javan surili (Presbytis comate), long tailed monkeys (Macaca fascicularis), Javan slow loris (Nycticebus javanicus) and Javan Gibbon (Hylobates moloch).
This study focused on Javan Gibbon as the indicator species, because it is one of the rare species of GGPNP and their habitat is fragmented. In 2011, the International Union for Conservation of Nature (IUCN) has categorized Javan Gibbon as endangered species. Hence, to find out the best solution, it is necessary to analyse the current suitable habitat and establish the habitat corridors to connecting fragmented habitat in GGPNP for sustainable conservation management this area. Corridor mapping is a new technic that helps to identify corridor and connectivity between fragmented habitats (Kharel et al. 2002).

The aims of this study are to determine habitat suitability and identify habitat corridor for Javan Gibbon to sustainable conservation management in GGPNP. This study is as a novelty to improve the wildlife conservation management.

Expectedly, this study can give some benefits to local government. It provides information about the condition of Javan Gibbon habitat, and basic information concerning how to reconnect fragmented habitat for sustainability conservation management in GGPNP.
The primary purpose of this study is to identify habitat suitability and corridor as the most important element of ecological network for Javan Gibbon habitat at GGPNP.
The total extent of GGPNP is approximately 22,851 ha divided into Cianjur, Sukabumi and Bogor administrative boundaries. This area lies between 106°51´- 107°02´ E and 6°41´- 6°51´ S with the elevation ranging from 700 m – 3,000 m above sea level and the topography varying from flat plains to mountainous. The rain fall and air temperature varying from 3,000 mm - 4,200 mm per year and 5°C - 18°C respectively. The main forest ecosystem types in the GGPNP are sub-Montana ecosystem (1,000 m – 1,500 m altitude), Montana ecosystem (1,500 m – 2,400 m altitude) and sub-alpine ecosystem (more than 2,400 m altitude).
