Balanda, M. 2012: Spatio-temporal structure of natural forest: A structural index approach. -Beskydy, 5 (2): 163-172The submitted paper deals with the analysis of stand structure of mixed species natural forest located in the Carpathians, Middle Europe. In order to evaluation of structural diversity we chose the combination of distance independent and nearestneighbor indices. Following structural indices were calculated: Shanon-Weaver index (S-W), diameter differentiation index (Td), Gigi coefficient (G), mingling index (DMi) and Clark Evans index (CEd). The permanent research plot with area of 2.5ha was established in National Naure Reserve Hrončecký grúň and subdivided into 25×25m subplots. The combination of mentioned indices was calculated for each subplot separately. Regarding the diameter heterogeneity, the most part of analyzed structures showed the moderate level of tree size differentiation (S-W value 0.393±0.074). The presence of high number of juvenile individuals which already reached the diameter category "above 2cm" did not significantly affect the diameter variation of investigated stand. On the other hand, a massive establishment of subsequent generation led to creation of spatial structure characteristic by high level of vertical differentiation (Gini coefficient 0.47 in the structure characterized as the breakdown with successive generation). High climax species richness was confirmed by calculated values of DMi index (maximum relative presence in the category from 0.3 to 0.4). Each tree was surrounded by two and more different species individuals. Analysis discovers the negative developmental shift in the DMi values towards to less differentiated structures. Regarding the horizontal distribution the analysis of CEd values indicated that investigated natural forest can reveal a random distribution of individuals regardless of developmental stage.

Abstract:The Winkelmass index as a forest management tool for inventorying stand structure. Spatial pattern of tree species, sizes and ages affects functional processes and biodiversity of forest ecosystems. Therefore, it is more and more important that stand structural diversity can be assessed through easy-to-implement methodologies at forest management scale. This paper discusses the application of a recently proposed index (the Winkelmass index) of tree spatial aggregation, based on the measurement of the angles between neighboring stems, to a beech (Fagus sylvatica L.) forest in Northern Latium (Italy). Results shows that the Winkelmass index can be implemented in a simple and fast way according to objective sampling schemes and allows to produce a raster map of tree aggregation pattern in the forest. Under the stand condition in the test area, only four trees at each sample point were sufficient to characterize prevailing stand horizontal structure.

“…A data file was then created and used as input to the statistical package STATISTICA for further analysis and contained 297 observations of diameter increment derived from 272 individual trees. The data file also holds records of dbh and stand variables such as stand basal area, the BAL index (BasalAreas -of-Larger trees; Wykoff et al, 1982) and the GD competition index (Gadow, 2003).…”
