Angkor Center for Conservation of Biodiversity (ACCB)

This guide to the Angkor Center for Conservation of Biodiversity outside Siem Reap opens with a striking ratio inside its enclosures and traces how founder Sam Veasna's rescue centre, opened in 2003 with backing from a German zoo, changed its approach. It follows the shift from patching up individual confiscated animals, gibbons with broken limbs among them, toward breeding entire species back from the edge of extinction. Walk the enclosure paths slowly, since many of the rarest residents sit in unremarkable pens.
