Dr Patricia Wright has found a 14-square-kilometre tropical rainforest in a remote part of Madagascar. She has been working with a team of scientists who have been documenting its natural wonders. Their work has been captured in a new documentary that's to be shown on French television next week. Dr Wright is the founder and executive director of the Institute for the Conservation of Tropical Environments and Centre ValBio, which is a world-renowned research campus in Madagascar.
