Abstract

SPATIAL PATTERN as one of the primary ecological concepts is an important criterion to understand changes in forest communities and monitor them. The applied methods in this respect are based upon two main strategies, full callipering and sampling. Using point map of trees obtained by full callipering method gives the opportunity to determine the true SPATIAL PATTERN of trees in a community. The methods of true SPATIAL PATTERN determination are classified as Quadrat, NEAREST NEIGHBOR and K-FUNCTION and its derivatives (L- and G FUNCTIONs). The aim of this research was to compare these methods in similar conditions and to study their advantages and disadvantages and also to utilize suitable statistical methods to evaluate the accuracy of the results. A 45 ha wild pistachio stand was chosen and the spatial positions of all trees were recorded by Differential GPS. The results showed that the SPATIAL PATTERN of trees is aggregated. The outcomes of the methods and their statistical tests proved their ability to determine the true SPATIAL PATTERN of trees in the study area. Also the comparison of the methods showed that each one can be applied, regarding the goal and available circumstances of future studies.
