The release of more than 600 orangutans into the rainforest of Borneo has been postponed once again.

Efforts to introduce them into the wild have failed largely because of a lack of safe forests for them to return to. An estimated 80 per cent of their habitat has been destroyed in the past 30 years.

Still, the Indonesian government is convinced that all orangutans can be released into the wild by 2015.

More than 30 are set to be released this year, with hundreds of others expected to follow.
