In Kenya's Shima Hills National Game Reserve, a protected biodiversity hot spot, the elephant overpopulation was leading to conflicts with the local farmers. Fortunately, Tsavo East National Park had the room and need to host animals due to their massive elephant loss of 1972.In an operation lead by Kenyan Wildlife Service 400 animals were earmarked for relocation at a cost of $3,200,000. Elephant families with five to twenty individuals were spotted from helicopters and darted with a powerful sedative. Once the animals were sedate crane trucks carefully lifted them into roomy transport vehicles where they were then given another injection to counteract the sedative. Two release spots, 250 and 300 kilometers away, in Tsavo east were reached by driving along bush trails. In 2005 a test group of 40 elephants were translocated - KWS wanted to assure that the exiled animals would not be tempted to return to their native forest. The program was deemed a success and operations resumed at the end of October in 2006 when the retmaining 250 began to be relocated.
