چکیده

The ecological significance of deadwoods has led to an everincreasing collection of related information to be taken into account in management plans. the coarse woody debris (cwds) is a significant component of forest ecosystems. here, managed and one unmanaged forest stands were selected in gorazbon district of kheyrudkenar experimental forest, noshahr, mazandaran province, iran. based on the fullcalipering inventory method, cwd attributes were collected in both stands. the distribution pattern of cwd was evaluated using univariate oring statistics. results showed that the highest and lowest decay classes in two forest stands were 36 and 12, respectively. results from distribution pattern analysis showed a random distribution pattern of cwd in the managed forest stand. overall, the unmanaged forest stand with 36 decay classes showed a random distribution pattern of cwd. conclusively, disturbances in the managed and the unmanaged forest stands occur in small scales.

Abstract
|
The ecological significance of deadwoods has led to an everincreasing collection of related information to be taken into account in management plans. The Coarse woody debris (CWDs) is a significant component of forest ecosystems. Here, managed and one unmanaged forest stands were selected in Gorazbon district of Kheyrudkenar Experimental Forest, Noshahr, Mazandaran Province, Iran. Based on the fullcalipering inventory method, CWD attributes were collected in both stands. The distribution pattern of CWD was evaluated using univariate Oring statistics. Results showed that the highest and lowest decay classes in two forest stands were 36 and 12, respectively. Results from distribution pattern analysis showed a random distribution pattern of CWD in the managed forest stand. Overall, the unmanaged forest stand with 36 decay classes showed a random distribution pattern of CWD. Conclusively, disturbances in the managed and the unmanaged forest stands occur in small scales.
