Abstract

Conventional ground monitoring of protected areas are commonly being conducted by foot or using light aircrafts. Time financial ability energy and safety are some of the main concerns during monitoring large landscapes. Monitoring of orangutans during night-time was arduous using conventional observation method. This study described the detection success of a thermal device (FLIR Vue 9Hz) attached to a Dji Phantom Pro 3 UAV to locate orang-utans at their sleeping sites in Semenggoh Nature Reserve (SNR) and Sepilok Orang Utan Rehabilitation Center (SORC) in East Malaysia. Using the thermal device we had captured images of orangutans in six separate locations and all the nests were then verified by ground-trothing. The white-hot mode of the FLIR VUE was feasible to detect orangutans in the forest canopy and in open areas. Open areas give the most accurate and clear thermal visual. Whereby the thermal visuals from the inner forest is limited to the density covered by the tree canopies. Results of this study demonstrated the feasibility of the method for locating mammals under large canopy. However there are several challenges that could be overcome and the future potentials of the method in relation to the rapid advancement of the drone and thermal imaging technology.
