Abstract

Today, determination of the ecological species groups for current and future situation of forest and its relationship with environmental factors is necessary for forest management. For this purpose, 50 plots were established in altitude range of 2091- 2811 meters above sea level and 600 hectare in protected area of western Dena. Four ecological groups was identified Using Twinspan analysis that altitude, slope and EC were effective in separation of groups. The second group with most grass cover located in low slope that soil conditions of it was best. But fourth group with Juniperus polycarpos, Ferulago angulata indicator species had unsuitable environmental conditions. In the first group, Pistacia atlantica was indicator species and this group had lowest altitude and highest lime and tree cover of oak. Also, results showed that classification of vegetation can up to 80 percent separately habitats accurately. So, these researches can help to identify of ecological niche of species and to understand of habitats situation.
