Abstract

The use of natural-licks by orangutans (Pongo pygmaeus) was investigated with camera traps in the Deramakot production forest, Sabah, Malaysian Borneo. The results showed that 1) Although orangutans were in the top three species at all the natural-licks, visitation frequency differed at the natural-licks depending on the surrounding environment; 2) Natural-licks use by orangutans was impacted more by human activity than concentration of the minerals; and 3) Visiting proportion of each orangutan class: flanged male, female with infant, and others, showed that flanged male accounted for 31%; female with infant, 17%; and others, 52%; although we had anticipated a bias toward the flanged male. These results suggest that the natural-licks are key habitats for all classes of orangutans and suitable sites for ground monitoring. Therefore, it is strongly recommended that other production forests adopt protection of natural-licks and managed as a monitoring site for orangutan habitat conservation. Furthermore, as orangutans are vulnerable to human activity, it is necessary to manage natural-licks as protected area with buffer zones of reduced human activity.
