Population dynamics and ranging behaviours of provisioned silvered langur (Trachypithecus cristatus) in Peninsular Malaysia

Tourists are attracted to the Bukit Melawati Kuala Selangor (BMKS) of Peninsular Malaysia, a small hill park, for both its status as a historical site and the free-ranging silvered langurs (Trachypithecus cristatus) that come for provisioning. We assessed the population trends and group sizes of T....

Tourists are attracted to the Bukit Melawati Kuala Selangor (BMKS) of Peninsular Malaysia, a small hill park, for both its status as a historical site and the free-ranging silvered langurs (Trachypithecus cristatus) that come for provisioning. We assessed the population trends and group sizes of T. cristatus over 10 years in the BMKS and examined their ranging patterns. Comparisons of observed populations between 2005 (190 individuals) and 2017 (193 individuals) revealed the stable demography and group sizes of the six T. cristatus groups in the BMKS. Based on a total of 185 location points of the six groups in 2017, their mean ranging area was 3.6 ha with a range of 0.86–6.93 ha with extensive spatial overlap. We also found a significant positive relationship between the six groups’ ranges and group sizes in 2017. Additionally, qualitative ecological comparisons with a previous study on T. cristatus in 1965 (before provisioning) suggest that the artificial food supply in the study area could modify the population dynamics and socioecology of T. cristatus. The modifications might alter their range size and territoriality in the BMKS. Overall, we found that provisioning had negative effects on the ecology of T. cristatus in the BMKS. Therefore, modifying management policies, such as banning feeding and implementing educational programs, may contribute to their proper conservation. © 2021, Japan Monkey Centre.
