The criteria used to evaluate the naturalness of forests consist in the free realization of natural processes going on in the forests as well as the existence of features shaped by these processes. Naturalness is interpreted as a continuous variable, where one of the extremes is provided by the artificial state (0% naturalness), whereas the other extreme is is that of the natural state (100% naturalness).
