In 2004 SANParks controversially decided to cull them because they are an alien species and were causing damage to the indigenous species. I agreed with that decision.
But, I can tell you for a fact that they didn’t get all of them.
Yesterday afternoon I saw three tahrs grazing right next to the path on Platteklip Gorge. They were right above the site where I saw someone jump to his death exactly 2 weeks ago.
