Wild land does regenerate, but also trees grow, and they have a cost to remove them when they get bigger, especially the roots. Plowing is not possible with tree roots everywhere, though perhaps non-monoculture non-mass-produced crops are possible to grow there and eventually the roots may decay. It can take 20-30 years for roots to decay though, or longer.
