In order to document spatio-temporal modelling abilities in the GIS environment, the observations conducted in the declined climax mountain Norway spruce forest during the recovery period (1995–2006) were used for simulation. The spatial extent of the explored site was composed of a set of 50 × 50 microsites, each with dimensions of 1 m × 1 m. The first case study simulates the influence of microsite positions in relation to the local tree crown projections on the survival of spruce seedlings from the seed year 1992. The second case study extends the previous study to include terms that determine the growth ratio in dependence on the crown projection area. The third case study provides further extensions in order to simulate growth ratio relations to the local soil type. The fourth case study demonstrates the local influence of the dominant grasses, such as Avenella flexuosa and Calamagrostis villosa, on the natural regeneration.
