Landscape metrics analysis in the proboscis monkey habitat in Kuala Lupak Wildlife Reserve

Abstract

Spatial studies of the proboscis monkey (Nasalis larvatus) habitat landscape are still limited in information to estimate the sustainability of their habitat in wetlands. Spatial analysis of the proboscis monkey habitat landscape is needed as important information for the preservation of the proboscis monkey habitat which is experiencing degradation due to land conversion. This study aims to analyze the spatial characteristics of the proboscis monkey habitat in the wetlands. Analyzing the characteristics of the proboscis monkey habitat, Worldview-3 data is needed to obtain information on land use and land cover by means of a GEOBIA-based classification, then analyzed using Fragstat 4.2 to obtain Class Area (CA), Number of Patch (NP), Edge Density (ED) values, Landscape Shape Index (LSI), Mean Patch Size (MPS), and Mean Shape Index (MSI) as the implementation of Proboscis monkey habitat characteristics. The results showed that the landscape of the Kuala Lupak Wildlife Reserve has an area of 4,952.10 hectares consisting of 3936 patches with an average area of 67,945 hectares/patch and a standard deviation of 409,2696. The total edge has an area of 1191712,536 meters and a density of 240,648 hectares. The Mean Shape Index has a value of 10.6713. The characteristics of the proboscis monkey habitat in the Kuala Lupak Wildlife Sanctuary illustrates the occurrence of fragmentation of the proboscis monkey's habitat and is not ideal for the protection of proboscis monkeys, because it can lead to isolated pockets of habitat. The results of this study are used as basic information for proboscis monkey habitat actions in the Kuala Lupak Wildlife Sanctuary.
