I live in a small city in the US, where it’s grass everywhere. There’s lots of rabbits, but why aren’t there more? They eat grass, and there’s clearly more grass than they can eat at their current population size. There’s no significant predators to speak of, I don’t think. They breed legendarily quickly, there’s even an expression about it. So if food isn’t a constraint, predators aren’t a constraint, what is the constraint? I would think they should just increase population until we don’t have to cut our grass anymore.

As an Aussie I can absolutely say that you don’t want lots of rabbits. They will fuck up the ecosystem bad if allowed to populate too far.
The US has many predators that keep rabbit populations in check, and this is why they are relatively low numbers. The opposite is Australia, fewer predators plus an ideal environment equal massive population. We only got them kind of under control through diseases
