One of the key modeling procedures is model verification, which ensures its reliability and confidence. In many respects, length crown an interesting biophysical property. Precise determination can be one components used in estimating mass needles or leaf area index (LAI), consequently amount transpiration carbon dioxide bound, crucial context climate change. The objective this study was to calculate Pinus sylvestris using allometric compare these results with actual ones establish degree discrepancy. that tested based on three predictor variables, i.e., diameter at breast height, tree stand density index. verification carried out empirical data collected for 300 sample trees 20 experimental plots located south-western Poland. All stands were pine monocultures habitats fresh mixed forest aged from 28 40 years. studied differed terms (0.68–1.81). comparison between (CLemp) calculated (CLcal) mean lengths expressed by correlation coefficient’, R = 0.955, a divergence (±) 4.57%. dedicated calculating crowns population level. uses index, constant value all within area. Further work needed improve allow precise calculation single tree, taking into account space it has disposal.
