Rangers of the Kenya Wildlife Service (KWS) winch up an elephant who had just been shot with tranquilizer darts fired from a helicopter to prevent suffocation near Narok town, some 150 kilometers northwest of the capital Nairobi, before being put in a truck to be transported to the Maasai Mara game reserve, about 100 kilometers south from Narok, 22 September 2011. The KWS aims to relocate some 200 elephants from Narok area to the Maasai Mara game reserve in a bid to protect animals from from escalating conflict with humans and ease the human-wildlife conflicts caused by increased farming and human settelement, and subsequent loss of elephant habitat. Out of the 9,299 human wildlife conflict cases reported in the last 10 years, 5,052 (54 per cent) are attributed to elephants, the KWS said in a statement. The 10-day operation to relocate elephants would cost 31 million shillings (230,000 EUR), the KWS Director Julius Kipng'etich said.
