Résumé

Norway Spruce growth in Central-South Finland appears less than predicted by the model based on Norwegian inventory, whereas pine and birch grow faster. The original model parameters indicated negative growth rates at large stand basal areas. Refitting of model parameters corrected the deficiencies. Stand age effect was included but found to be weak. Site fertility index fitted to diameter growth observations become higher on dryish sites, compared to mesic sites. Such finding agreed with greater stand basal area increment rate on the dryish sites. Reasons for the apparent site fertility discrepancy are discussed.
