THE COMPARİSON OF THE NATURAL STANDS QUANTİTATİVE CHARACTERİSTİCS İN MANAGED AND NON-MANAGED AREAS İN CASPİAN SEA COASTAL FORESTS

Abstract

In this consideration the natural forest stands in managed and non-managed areas in Iran’s North forest were studied from the view point of quantitative characteristics. Inventory was done by random systematic method and with a net of 112×112 meters dimensions with sample pieces of 500 square meters. In each sample piece the quantitative characteristics of breast height sections Basal Area (B.A) and the number of trees in a hectare were considered. ANOVA was used for testing the significant difference among parameters of quantitative means in the two areas the results of this study showed that from the view point of quantitative characteristics among Basal Area in hectare and the number in hectare in the two managed and non-managed areas a significant difference exists.
