Prince William has released a statement following news of Anton Mzimba's death.
Mzimba, head of services at Timbavati Private Nature Reserve, was hailed as a "wildlife warrior", fighting off poachers at the reserve where he worked for over 25 years.
He was shot and killed on Tuesday. Further details around his death are unknown.
The Duke of Cambridge met with Mzimba via Zoom last year when they learnt about a new device to combat ivory smugglers.
"This is a very well-organised crime. It involves local people. But, down the line, it goes across the border of the country," Mzimba told the prince, per People.
