| Title : | COMPARATIVE ANALYSIS OF RESULTS OBTAINED FROM DIFFERENT SHAPES OF SAMPLE PLOTS IN PARTIAL INVENTORY OF HIGH BEECH FORESTS IN MONTENEGRO |
| Abstract : | The paper presents the results of a comparative analysis of the number of trees, stand volume and the position of the height curve within the height overdiameter curves, obtained through a partial survey of high beech forests on different shapes of sample plots: concentric circles used in Montenegro (CC CG), concentric circles used in Serbia (CC RS) and angle count sampling (WZP RS) applied in the Serbian forest inventory. Data processing was conducted in Osnova software and within a GIS environment. Height curves were modelled using the Näslund function, while spatial interpolation of results was performed using the Spline with Barriers method. Regarding the average number of trees and average volume, although the CC CG method produced the lowest values, it is difficult to determine which plot shape is superior. The reason lies in the differing elements of partial survey designs among the tested plot types (number, size, sampling intensity, number of detailed subplots, etc.). However, since the studied stand belongs to selection forests, which represent extremely heterogeneous structural forms, we consider that priority should be given to angle count sampling (WZP RS). This method is based on unequal probabilities of tree selection for measurement, specifically the likelihood of a tree being selected is proportional to its diameter which undoubtedly contributes to a more reliable determination of stand volume under the given conditions. Furthermore, we consider that the method of selecting trees for height measurement in the forest inventory of Montenegro does not ensure a representative sample for accurate modelling of the height curve. As a result, poorer height classes are determined, leading to lower stand volume values. Spatial visualization through raster analysis facilitates planning and decision-making in forest management planning, as it provides a more realistic insight into internal stand variations that are often overlooked in conventional tabular presentations. In this context, GIS software and raster analyses represent efficient tools for the assessment, comparison and visualization of field data results, enabling better decision-making and improvement of forest resource management. |
