One Planet presents Animal Migration in a climate of Change, a series of programmes exploring the way that animal migration has been affected by environmental changes.
In Part Three, The Elephant's Journey, Brett Westwood looks at African elephant migration.
Mac, the African elephant, travels each year between Kruger National Park in South Africa and the private nature reserves which have been created to preserve animals and habitats there.
Until relatively recently, reserves have been fenced, and elephants have not been allowed to make their traditional journeys to find water, or, as in Mac's case, to wander in search of a mate.
Now that the fences are down in many places, for the first time for decades, elephants can resume their traditional journeys and biologists are following Mac's migration with keen interest, because the experience in South Africa, could be a template for elephant management in other parts of Africa.
With location reports from Mac's "follower", scientist Michelle Henley, and experts in elephant behaviour and management, Brett Westwood explores the future for elephants such as Mac in a continent where people and elephants are often in conflict.
First broadcast on 02 October 2008.
