It depends on what you want. North American wetland communities didn't evolve with pigs on the landscape and, because they root and wallow, pigs can be pretty tough on wetland plants. Cattails put out a ton of biomass, but unlike cows or deer, pigs aren't as good at digesting cellulose, and they'll tend to preferentially graze easily digestible fruits, seeds, and plant parts before going for the tough stuff. But if you're only keeping a couple animals, it shouldn't cause significant damage. My advice would be to err on the side of caution- low stocking densities, reasonable rotation rates, and I don't think there should be much trouble.
