Standing up to 30 metres tall, Madagascar's giant baobab trees have towered over the island for thousands of years – but as the large animals that used to spread their seeds have died out, the trees' survival is threatened. New research indicates that much smaller species have an unexpected role in helping baobabs thrive.
One of Madagascar’s most photographed tourist sites is the Avenue of the Baobabs near the city of Morondava, in the west of the island, where giant, stately baobabs line a dirt road.
