I would say, to the best of my knowledge as a biologist, that winter die-off is the limiting factor for ungulate herds. It's not lions and bears and wolves and humans and cars. Every so often, every 20 years or whatever, you get a massive winter die-off. And it takes quite a while for those populations to build back up. Predators can keep that at a lower rate. They cannot affect it.
