Priority restoration area mapping of Javan Gibbon Habitat (Hylobates moloch Audebert 1798) in Gunung Halimun Salak National Park as a result of global climate change

Abstract

Gunung Halimun Salak National Park is a widest tropical rainforest conservation area that still exists in West Java and Banten Provinces. The park has been facing deforestation, forest degradation and forest fragmentation problem, on the other hand the area is a natural habitat of Javan Gibbon, so habitat restoration is important to maintain its connectivity. The aim of this study is to provide information to the park administration about the potential area which can be restored to facilitate Javan gibbon movement. The analyses were performed in Condatis, a modelling software for use in landscape planning to explore the connectivity of the wildlife corridor, based on species movement in response to climate change. Variable data prepared in the form of a raster is habitat data, Javanese gibbon habitat suitability data through Maxent application, data source and target layer. The bussines as usual (BAU) scenario and restoration scenario are created by illustrating changes in landscape connectivity by converting non-forest areas into forests. Corridor areas and paths can be indicated by high flow values from BAU scenario, while priority restoration areas are indicated by changes in flow values between scenarios. Priority restoration areas are divided into 3 classes: high, medium and low, high and medium classes are found in the Cikaniki Tea Plantation area, the Pasir Kerud forest block and Muara Tilu.
