Abstract

There is increasing pressure worldwide for maintenance of forest sustainability. Concerns about environmental and social issues associated with forest sustainability - such as effects on biodiversity changes, area, vitality, health, wood and non-wood production of forests - have led to international agreements and programs for improving FOREST MANAGEMENT practices. One of the problems that forest experts are facing in Iran is the existence of COW-PENS and the effects of LIVESTOCK GRAZING on forest trees. This research aims to study the effects of grazing resulting from COW-PENS on TREE SPECIES DIVERSITY. For this purpose, two compartments in which COW-PENS exist and two ones out of reach of livestock were selected in Gorazbon District belonging to the experimental Forest of Kheyroud. In both regions the forest types are Fageto-Carpinetum. Using 100% inventory and SAMPLING methods, heterogeneity and evenness indices of Shannon and Simpson were calculated. Heterogeneity indices of Simpson and Shannon-Wienner and evenness index of Shannon were greater in grazed region, but evenness index of Simpson were approximately the same in both regions. Using t test for Shannon index, there is a significant difference between 100% inventory and SAMPLING method in grazed region with 13 sample plots, but in ungrazed region, the difference is not significant with 23 sample plots.
