Lions at Addo National Park. Addo Elephant Park was proclaimed in 1931, as a safeguard for the last 11 wild elephants roaming the area. It is now home to over 350 elephants and numerous other species. Addo Elephant Park was so successful that it started to get overcrowded, so surrounding land needed to be acquired. With local co-operation, adjacent farms were purchased and the new Greater Addo National Park will soon cover 1.2 million acres (492,000 ha).
