A Comparison of Forest Stand Quantitative Factors in Protected and Nonprotected Areas in Arasbaran Forests

Abstract

In this research, a part of forest stand in two protected and nonprotected areas have been compared
for quantitative factors. Initially the similarity of these stands using aerial photographs in 1: 20000
scale of 1968 was studied and the similar stands were chosen. Then 92 line samples with a network
size of 150 x 300 m in nonprotected parts of stand are sampled out and compared with other 92 line
samples recorded from protected areas. From quantitative factors, basal area of stand and number of
trees perhectare were determined. The number of trees and basal area in protected area was
significantly higher than that in nonprotected forest stands.
