Southern Thailand is the Thailand we think we all know. It's a place of both spectacular natural beauty and of wild parties, but behind this well-known image is also a place of unexpected surprise, where spirituality pervades every bit of life. For the animals that live here, this is natural wonderland.

In Central Thailand's forests, fertile plains and even city streets, nature finds a way of living alongside people. Away from the skyscrapers of Bangkok and the manicured lawns of Lumpini Park, where enormous water monitor lizards mingle with the picnicking families, a ceremony epitomising the Thai Buddhist notion of 'making merit' takes place.

Northern Thailand is dominated by mountains and cloaked in forest. It hides ancient creatures and surprising partnerships. As this remarkable wildlife documentary shows, to survive here, both the wildlife and people rely on maintaining the natural harmony. Leaf monkeys live up to their name eating the leaves of around a hundred different types of plant, while incredible painted bats fly overhead.
