The Queen of Trees (S24E03)

Ian Holm narrates the extraordinary story of the African sycamore fig tree and its symbiotic relationship with a tiny insect partner, the fig wasp. Neither could exist without the other, and in turn they support hundreds of other animals from ants to elephants. Each fig is a world in miniature, a stage for birth, sex and death as the tiny players battle against predators and parasites. (BBC)
