In the Netherlands, growth and yield research on Scots pine was done from 1949 to 2002. This includes studies by Becking and by the Dorschkamp/IBN research institute. Together with the permanent sample plots from the timber prognosis system HOSP, all this comprises a dataset of 94 plots with 348 recordings. For the development of top height htop with age (t), Cieszewski’s model with site index h70 and 3 additional parameters fitted best. The diameter development up to stand height of 7 m was best described with the model by Jansen et al. based on htop and initial density N0. From a stand height of 7 m and up, the basal area increment iG was best described by a power func-tion based on htop, calendar year (yor), h50 and the stand density index of Hart (S%). For S % > 20.6 the basal area increment drops strongly with increasing S %. The effect of thinning on diameter after thinning was modelled with a modified La Bastide-Faber model. With all models together, a stand projection model was constructed, which follows the measured stand development reasonably well. The model was used to construct yield tables with five site classes and four thinning intensities.
