Maybe I will suggest a book bit of the topic, but it may give you a bit different angle on South African hunt.
Try the book: "The new game rancher" by Pamela and Peter Oberen.
It is about modern game farming, low and high fences, sex ratios of farmed species, diseases, disease free buffaloes, predator control, etc...
Generally it covers all except for hunting, but once you step a foot on any commercial hunting farm many things will be crystal clear, whatever is that you may see.
It is very enlightening.
I bought this book on Johannesburg airport, but it is available on amazon.
On the subject of hunting, I find the books by Col. Craig Boddington very educational, second to none on this subject.
Another one: Mammals of South Africa, pocket guide, or any similar book, for quick identification of local wildlife/
