The 43-year-old elephant will soon be relocated to the reserve near Vaalwater in Limpopo.
The move is being facilitated by a team of experts at Four Paws International and the Elizabeth Margaret Steyn (EMS) Foundation.
The team is preparing Charley by training him to enter a crate that will be used to transport him to the reserve, which is about a three-hour drive away.
Charley was originally captured in Hwange, Zimbabwe, over 40 years ago and trained to perform in the Boswell-Wilkie Circus.
He has been at the zoo for over 22 years after being in the circus for about 20 years.
Charley was transferred to the Natal Lion Park when the circus closed.
He has been at the Pretoria Zoo since 2001.
Charley’s mate at the National Zoological Gardens in Pretoria died in 2020.
