Comparing South Africa as a whole and saying animals are more alert than a wild concession area in a different country is a ridiculous comparison. A concession area is maybe 100k acres, it has the same species throughout, and generally consistent use pressure (human activity, hunting, poaching, fishing, etc) throughout the concession. The same 100k acres in South Africa would be at least 10 high fenced farms, maybe 20 with some different species on each and a different level of use (farming, hunting, etc) on each farm. The wildlife on each farm has the ability to be very different from the adjacent farm. Some farms I’ve seen in South Africa have been very wild hunting and others not so much. South Africa is also a very big country and intense game farming more prevalent in certain areas than others.
