- Each static and dynamic factor was divided into classes, each of which was attributed a score related to its paludification “power”; 0 = null “power”, 1 = low “power”, 5 = high “power”. Adding up the score of each factor, gives a Paludification Index that estimates the liability of each stand to paludification.
-
1According to Sims and Baldwin (1996).
-
2In cm. In our paludification index, we used the median value of each class.
-
3According to Sims et al. (1989).
