THESE are the incredible elephant nannies - who raise orphans like they were their own babies. The British students and volunteers feed, clean and play with young elephants who have been abandoned by their mothers. Together they help provide 24-hour care to the captive herd at Knysna Elephant Park, in South Africa. They include Abigail Hearn, 24, from Brighton, PHD student Lisa Howard, 28, from Somerset, Melisa Dora, 25, from London and 21-year-old Paige White from Bristol. The foursome are currently caring for a eight-week-old baby elephant, Fiela, who was rejected by her mum and will be raised by humans for the next two years.
