摘要

In Malaysia, conservation programs for translocation areas of the Asian elephant (Elephas maximus) started since 1983. Currently, forest fragmentation creates a situation where the protected areas are isolated from one another. Due to competition for resources and space at the release site, protected areas (PAs) are crucial for the Asian elephants as they are dependent on healthy forests for their daily activities, food security and source of water. Thus, a study on the home range and habitat utilization of a translocated elephant is required. This involves analysis of distribution and habitat parameters of this mammal for protection purposes as well as maintenance of environmental stability. This study aims to analyze the habitat preference of translocated Asian elephants at two different sites using remote sensing technology and Geographic Information System (GIS). The home ranges of the elephants using satellite transmitter are investigated as a means to assess the habitat parameters preference and their distributions. The satellite images and topographical maps were used to generate the environmental and topographical habitat parameters encompassing land cover, forest status, Normalized Digital Vegetation Index (NDVI), water sources, Digital Elevation Model (DEM) and slope respectively. Findings of this study showed that there is a strong relationship between distribution of elephant and forest type particularly secondary forest and availability of permanent water sources. However, topographic parameters particularly the elevation and slope, were identified as less significant habitat parameters in elephant distributions. The results of this study confirms that conservation of the Asian elephants require large areas of continuous and effectively protected habitat particularly in translocation areas where the wildlife is best conserved by protecting existing natural habitats. However, tolerance to elephant presence outside PAs is essential where food resources are often abundant for elephants.
