Abstract

The 26th years pure stand of cupresuss sempervirens with 40 ha and 2*2 m distance among trees in Abas Abad was selected to study increment of cupresuss sempervirens. The 100*75 m net and random-systematic method was used for this research and also increment factors were measured in 50 sample plots. Diameter of all trees and height of four trees were recorded in each sample plot. Results showed that viability was 58.6% after 26 years. Quantitative parameters including mean diameter, height, basal area, and volume were 12.84cm, 13.3m, 20.56 m2/ha and 99.33 silve/ha, respectively and also some parameters about increment including diameter increment, height increment, basal area increment and volume increment were 0.49 m, 0.511m, 0.80 m2/ha and 3.82 silve/ha, respectively.
