> If you have an actual sound ecosystem, in a sufficiently large habitat area (not encroached by humans, roads, etc.), culling is rarely necessary. It's really a question of the extent to which humans get bothered when prey populations get too big and then they leave the preserve and start getting hit by cars. Or too many wolves and they start killing farmers' sheep. Culling helps avoid the wild swings in population. I'd also point out that even with populations that are not in good shape (threatened or declining), selling super expensive hunting licenses can still make sense. If $50,000 = +3 rhinos, let the hunter kill the rhino. Of course there are perverse incentives and all sorts of practical difficulties, but I just want to make the point that it's possible for that sort of thing to be in the best interests of the species being conserved.

Yes, it is a possible model, but I don't know of anywhere where it is actually shown to work. And yes, there are lion farms that are really sad examples where they are bread to be hunted, and they are not living in natural conditions. Part of the problem is that the [-1 rhino] is a guaranteed figure, and may increase, but [+3 rhino] is speculative, requiring many steps that may go wrong, from mating, fertilization, gestation, birthing, survival to adulthood; bird in the hand vs bird in the bush. It may turn out that the number is more like $1.5 million for a license than $50k, which already seems outrageous. I also have close family who work directly with African wildlife foundations and although I've heard much discussion of solutions, I've never heard any mention of this as being viable.
