Abstract

In order to analysis the IMPORTANCE VALUE and spatial pattern of woody species, Sardabrrod forests located in Chalous were studied. With considering the study areas covers 306.2 ha, and 84 sample plots with 400m2 (20 m × 20 m) were established by a random systematic method. All trees larger than 7.5cm in diameter at breast height on plots were recorded for analysing to spatial pattern. Seven ecological units were indentified using Pc-Ordination software. After calculating the relative frequency, density, abundance and mean IMPORTANCE VALUE (IV) index, Carpinus betulus had the most IMPORTANCE VALUE compared to the other woody species. Based on the IMPORTANCE VALUEs, Parrotia persica, Fagus orientalis, Acer insign and Acer compester had the most IMPORTANCE VALUEs, respectively. Thus, the spatial pattern of these species was statistically analysed. Variance to mean ratio (general procedure) showed that Parrotia persica have higher spatial index than other dominant woody species. Carpinus betulus, Fagus orientalis and Acer insigne had next priorities. CLUMPED PATTERN were confirmed for all mentioned species considering spatial index > 1 and these results coincide with Green and Morisita standardized indices.
