The donation to the Naankuse Lodge and Wildlife Sanctuary was made through the Jolie-Pitt Foundation in the name of their daughter Shiloh, who was born in Namibia.
In a statement released Monday, Angelina said "We want her to be very involved and grow up with the understanding of her country of birth."
Angelina said the owners of the sanctuary are old friends. "We continue to be impressed by their hard work and dedication to the people and conservation of the land and wildlife of Namibia," she said.
The family spent Christmas together at the lodge, where staff say the children helped to feed and care for orphaned baby baboons and foxes and saw a leopard released back into the wild.
