Malaya GReP

The Malaya Gibbon Rehabilitation Project (Malaya GReP) is Malaysia’s first small ape rehabilitation centre, established in 2013, that helps orphaned captive gibbons and other primates that were confiscated from wildlife traffickers or surrendered by civilian pet owners.

This project aims to continuously give proper care, nutrition and rehabilitation to as many primates as we can accommodate, so they can reclaim their survival skills and be returned back into the wild to become a functional part of the natural ecosystem. In order to return to the wild, gibbons must be both physically and mentally ready, as well as achieve 7 criteria of release.  We follow the IUCN Best Practice Guidelines for Rehabilitation and Translocation of Gibbons. Malaya GReP has been accredited by independent auditor sent by IUCN which are the European Alliance of Rescue Centres and Sanctuaries (EARS) and Wildlife Impact.

Get to know the gibbons

Every gibbon has their own personality. Some are shy while others are very social. Some are mischievous, while others are always trying to out smart their human caretakers. At GCS we strongly advocate that #EveryIndividualMatters and that their rehabilitation is suited to their individual needs. Find out more about our gibbons, their characters and their stage of rehabilitation.
