Addo Elephant National Park is a diverse wildlife conservation park situated close to Port Elizabeth in South Africa and is one of the country's 20 national parks. It currently ranks third in size after Kruger National Park and the Kgalagadi Transfrontier Park.
The original section of the park was founded in 1931, in part due to the efforts of Sydney Skaife, in order to provide a sanctuary for the eleven remaining elephants in the area. The park has proved to be very successful and currently houses more than 600 elephants and a large number of other mammals.
The original park has subsequently been expanded to include the Woody Cape Nature Reserve that extends from the Sundays River mouth towards Alexandria and a marine reserve, which includes St. Croix Island and Bird Island, both breeding habitat for gannets and penguins, not to mention a large variety of other marine life.
These marine assets form part of the plan to expand the 1,640 km² Addo National Elephant Park into the 3,600 km² Greater Addo Elephant National Park.
The expansion will mean not only that the park contains five of South Africa's seven major vegetation zones (biomes), but also that it will be the only park in the world to house Africa's "Big7“(elephant, rhinoceros, lion, buffalo, leopard, whale and great white shark) in their natural habitat.
