Abstract
The Silvery Lutung Trachypithecus cristatus is recently listed as Vulnerable based on the assumption of the extensive habitat loss from forest fires, oil palm plantations and hunting. To review its status, we conduct a mega transect survey on 7 October 2023, to estimate the populations along 50 km of Banyuasin Drainage, Sumatra, Indonesia. We have been conducted census to assess population size of T. cristatus. Our survey found c. 500 individuals were documented in Banyuasin Drainage. Based on the proportion of survey site, it is assumed that the total number of T. cristatus in Banyuasin Drainage could approach 1.000 individuals. There is not enough evidence if this primate has become an annoyance for the primary crops of native farmers. Furthermore, no proof of capturing or hunting from native residents who keep T. cristatus as a favored animal. This study indicates T. cristatus is the most abundance primate in fluvial habitats of Banyuasin River, South Sumatra.
