| Description: | A study of elephants' home range and movement patterns during construction and inundation of Hulu Terengganu Hydroelectric Dam, Terengganu was carried out between April 2014 and December 2015. This study aimed to investigate how construction and inundation of the dam affect the elephants' home range, movement rate, and habitat selection. Two elephants were fitted with GPS satellite transmitter collars during the dam construction for five to six months. Another three elephants were collared for one to four months after inundation. The locations of each elephant were analysed using BIOTAS software to estimate their home range and movement rate and pattern within the dam catchment area. The home range of dam construction was estimated between 96.53 km2 and 367.99 km2, while during inundation were estimated between 158.13 km2 and 590.45 km2 suggesting that during construction, the home range was smaller compared with the home range during inundation. The home range size during inundation was comparable with the home range in the secondary forest in Sabah. The daily distance travelled (or movement rate) was estimated between 1.33 km/day and 1.92 km/day during construction, and between 1.19 km/day and 1.70 km/day during inundation. The rates during construction and inundation fell between 1 km and 2 km per day. This is comparable with the movement rate of elephants in the secondary forest in Sabah. Based on the location fixes, 92% fell within the secondary forest, while 8% fell within the primary forest. This indicates that elephants preferred secondary forests. This thesis concludes that there were direct and indirect impacts of construction and inundation of the dam on the elephants' home range, movement rate, and habitat selection. Nevertheless, elephants have the capability of adapting to these changes, with no reports of displaced and conflicted elephants. The home range size and movement rate stabilised at the end of the inundation process. Thus, construction in the elephant habitat is acceptable, provided that the surrounding habitat is large enough to maintain the elephant population. Based on the data, a theoretical impact model of dam development on elephants' home range and movement was developed which among others predicts that i) elephants' home range and movement are affected by dam development, and ii) that they can adapt to changes during development as long as the surrounding habitat is large enough to satisfy their needs.,Certification of Master's/Doctoral Thesis" is not available |
