Old trees, including old oaks, paper barks, camphors and the indigenous and protected Outeniqua and Cape yellowwood are being ring-barked in the Tokai forest.
Ring-barking is a very effective way to kill very large trees.
However, some conservationists have expressed opposition to this, especially as South Africa marks Arbor Month during September.
The month is meant to highlight the essential role trees play in sustainable development and the livelihoods of people and the environment.
