چکیده

Dena biosphere reserve located in iran and is a 550 biosphere reserve in the worlds. this research was investigated in the two protected and non-protected areas, in a dena biosphere reserve, kohkeloye va boyrahmad province, and central zagros forest, southwest of iran. inventory methods designed by systemetic-randomaiz method by use the rectangular plots that were 15×30 meters in the 100×100 m net. in each plots information include qualities and quantities tree parameter measured. t-test was used to analysis of mean quantities tree parameter differences between protected and non-protected area. data analyzing was done by excel and spss16 software’s.results showed that the dbh distribution in the reduced uneven- aged stand in protected area and reduced even aged in the non-protected area. results showed that the mean of forest characteristics including dbh, height, canopy cover and, and density in the protected area are 38.5 (±5.5), 6.51 (± 0.9), 38 (±5.5) and 530 (±35) and this quantities parameters in rotected area higher the non-protected area. overall results showed that the qualities and quantities tree parameters in the non-grazed area higher the grazed area, and grazing has a negative effect on the qualities and quantities tree parameters.
