He will, however, have an official farewell meeting with his Commanding Officer when he returns from Africa.
The Prince has worked with conservation experts from several organisations, including the Zoological Society of London (ZSL), to design a programme that will give him first-hand experience of the challenges faced by those working to protect wildlife and local communities in Africa.
A spokesman for Kensington Palace said he would learn about environmental education programmes and the importance of linking the future of wildlife with the sustainable development of the communities alongside it. "Additionally, Prince Harry will spend time working with experts at the sharp end of wildlife protection. He will join a team of rangers who are the first to respond to reports of poaching attacks on elephants and rhino," the spokesman said.
The Prince will also work with leading vets who treat animals that have survived the removal of their tusks and other brutal attacks.
Jonathan Baillie, director of conservation programmes at ZSL, said that Prince Harry's work would have real value for the global conservation movement.
He said: "After this period, Prince Harry will be one of the best-informed ambassadors for the conservation community on what is really happening on the ground in Africa. His experience will be of great value."
The Prince will officially remain a member of Britain's Armed Forces for life, but will no longer be paid by the Army or carry out duties.
