The processes for releasing a zoo-bred Sumatran orang-utan Pongo abelii at Bukit Tigapuluh National Park, Jambi, Sumatra



Perth Zoo released a sub-adult ♀ Sumatran orang-utan Pongo abelii in November 2006 into the protected Bukit Tigapuluh National Park in Jambi, Sumatra, where the Sumatran Orang-utan Conservation Programme (SOCP) is trying to re-establish an orang-utan population. This was the first release of a captive-born orang-utan into the wild. Temara is being closely tracked and monitored by Perth Zoo and SOCP staff. The aim is that she will be followed for at least 2 years. This paper describes: the pre-release preparation, the release process, the benefits of the programme, the monitoring process and the post-release results.
