Simple, if you go wild you have to think wild if rabbits venture into your patch dog poo, human urine works for a while, but a dead rabbit will work better and longer. As for Bison, that will be pretty much the same cows dont go near dead beasts and I think you'll find bison will be the same... trouble is droping a bison while it's in or near your patch, G'Luck with that lol. I've had prob's with rabbits, but on the whole they dont do much damage if you grow big plants. Use wire netting while if you plant your plants small or grow them in beds or pots you can tranplant later once they start to become woody at the base.
