The Barbados Wildlife Reserve, set up by primatologist Jean Baulu in 1985, as a sanctuary for the green vervet monkey which were being killed as pests by local farmers. In the cool of a forest lives the vervet monkey. Even these have a price on their heads. Driven into hiding and on the brink of extinction, these chattering skittish grey animals owe their lives to Jean Ballou who believes, that they are worth saving. Today they are found all over the world. Relive what Jean has taken 30 years to learn.
