Yeah, they are wild buns. The product of released pet rabbits in an environment with not many predators.
With the tourism angle though I'm hoping that they preform some level of maintenance for the buns, but probably not. To be honest the tourists themselves probably do the most damage, I wonder how many tourists turn up with a bag of lettuce and carrots for them. If I ever went I'd be there with a bag of SS pellets and some hay cakes or something! :lol:
