NAIROBI BABOONS – THE OLIVE TROOPS! - BY GARETH JONES Not too long ago much wildlife roamed freely in the Nairobi area as there was very little human development, however in the last 100 years the city has grown dramatically and most of the species that were saved now reside inside the Nairobi National Park. However as Nairobi has so many large trees, many arboreal species have continued to move over a larger area. Some of these 'roaming' species include several species of monkeys and olive baboons.
