This is exactly what happens, I've seen it first hand. The land is kept is more of a natural state to preserve it for hunting. Some are hunted for trophies etc., but the numbers that are taken are controlled so that you have another batch the next year.... keep in mind that many of these places are huge (100's of acres) with high fences etc. and becuase each animal has a dollar value, more common species usually start at $400 (Bleisbok) and can go up to $50,000+ for Cape Buffalo the economic incentive to preserve the speces is pretty strong... and lucrative.
