The department was replaced by Kenya Wildlife Service (KWS) in 1990, and Leakey became its first chairman. With characteristically bold steps Leakey created special, well-armed anti-poaching units that were authorized to shoot poachers on sight. The poaching menace was dramatically reduced. Impressed by Leakey's transformation of the KWS, the World Bank approved grants worth $140 million. Richard Leakey, President Arap Moi and the WMCD made the international news headlines when a stock pile of 12 tons of ivory was burned in 1989 in Nairobi National Park.
