MOVE : MOdel for terrestrial VEgetation version 4.0

Samenvatting

The model MOVE4 predicts the probability of occurrence for over 900 plant species based on the Ellenberg indicator values for acidity, moisture, nutrient availability and salinity, the geophysical region and the vegetation type. The model was developed as a follow up of MOVE3.2. Although extensively tested and applied, the principles and the tests of the model were never laid down. This report fills this gap and contains the principles of MOVE4 and the internal tests that were carried out. The tests show that the model gives reasonable results predicting the probability of occurrence of plant species, but that there is room for improvement.
