KENYA - The text message from the elephant flashed across Richard Lesowapir's screen: Kimani was heading for neighbouring farms.
The huge bull elephant had a long history of raiding villagers' crops during the harvest, sometimes wiping out six months of income at a time. But this time, warned by the message sent by a mobile phone card inserted in Kimani's collar, ranger Lesowapir, an armed guard and a driver arrived in a jeep bristling with spotlights to frighten Kimani back into the Ol Pejeta conservancy.
