The marginal economic benefit of trophy hunting is not well known, and rarely studied. Pro-trophy hunting organizations often present estimates of gross economic activity associated with hunting to promote their view that trophy hunting equals conservation because of its economic value. However, given past experiences of unsustainable trophy hunting leading to serious population declines and ultimately bans on trophy hunting, one cannot automatically conclude that simply because there are economic activities associated with trophy hunting, that this is inherently benefiting conservation.
