The effect of elephants (or generally wildlife) being aware of where they are in danger is starkly visible in South Africas Krüger National Park: It's right on the border to Mozambique. On the South African side, wildlife is abundant and fairly well visible, but once you cross over the border, there's no visible wildlife. Some elephant droppings on the road, that's all.
