Three methods for modelling potential natural vegetation (PNV) compared : A methodological case study from south-central Norway

Auteur(s) et Affiliation(s)



Description :
The vegetation was mapped in a south-central Norwegian mountain region around the village of Beitostølen, in 2009. The actual vegetation map (AVM) formed the basis for the development of PNV, a hypothetic natural state of vegetation that shows nature's biotic potential in the absence of human influence and disturbance, using 3 different modelling methods : (1) an expert-based manual modelling (EMM), (2) rule-based envelope GIS-modelling (RBM), and (3) a statistical predictive GIS-modelling method (Maxent). The article compares the modelling results and shows that the 3 modelling methods have different advantages, challenges and preconditions.
