How elephants were relocated from Mt Kenya park by road.

The Huge Wildlife Relocation.

Kenya Wildlife Service rangers loading a tranquillized elephant onto a truck during a translocation exercise from Mt. Kenya to Ithumba Camp in Tsavo East National Park, one of Kenya's oldest and largest parks. The country's wildlife officials kicked off a relocation operation for 30 elephants in a bid to "reduce human-wildlife conflicts", fitting monitoring collars on the tranquillized animals before using cranes to swing them, upside down and with bound feet, onto flatbed trucks

Tsavo Park is huge enough to accommodate 30,000 elephants but currently has about 12,000 and it unlikely to expect that the animals will interfere with human settlement there.

The translocation operation involved co-ordination between ground and aerial teams. 

A fixed wing airplane flew over a herd of elephants, shepherding them onto an open field. From another aircraft, a ranger fired tranquilizers into the targeted jumbos. Once the animals fell, the ground teams moved in to ensure that they were properly sedated and comfortable before more teams began the uphill task of loading them onto waiting trucks while ensuring they remained hydrated and did not suffocate.

The elephants are a big tourist attraction in Kenya but they also face huge risk of poaching due to high demand of ivory in Asia.
