I cannot answer your question directly as I've never raised pigs, however I have observed many pigs and it seems to me that a lot of the rooting and destruction of plant life is just for something to do. In other words keeping the pigs busy and mentally entertained might go a long way toward saving some of the plant life of your pig-area.
Pigs are smart so maybe hiding root veggies inside boxes or hay bails so they have to 'work' for a meal, etc. - or running the pigs with other farm animals or adding other distractions would help. I believe moving animals to new paddocks keeps them busy and entertained discovering new land, so whatever you can do for habitat enrichment would be part of the solution to your question.
thank you, Rustysdog. While I know that observation is best, I am the sort who finds comfort in numbers I can crunch. 4 pigs/acre is a good starting point for calculations.
Walter, thanks for the links. How big is any one paddock when the pigs are in it? And how long are they in there before you rotate?
