Macaca fascicularis (Raffles, 1821) Fig. 13 A Long-tailed macaque Notes. Macaca fascicularis was the most observed species detected via all detection methods, with 41 individuals (Table 2) were observed on foot surveys and multiple camera traps throughout both national park forest areas (6 different transects or camera sites) and human-disturbed forest areas (6 different transects or camera sites) on the island. There is one small troop that can be seen in the southeast area of the island; however, this troop stays near the road and residential areas as humans intentionally leave food items. This lone troop behaves differently than the other troops. The wild troops encountered were very well hidden in the forest areas away from human settlement areas and throughout the island (Fig. 6).
