Habitat suitability modeling for Juniper (Juniperus foetidissima) in Arasbaran Biosphere Reserve

Juniper (JuniperusfoetidissimaWilld.) is classified as a Least Concern (LC) species of the International Union for Conservation of Nature (IUCN), but its distribution has decreased as a flagship and longevous species in East Azarbaijan province during last decades, and hence it is important to protect its habitats. In this research, the habitat suitability of Juniper in Arasbaran biosphere reserve, as the only habitat of this species in Iran, was considered. For the habitat suitability modeling of this species, Ecological Niche Factor Analysis (ENFA) method and ENFA software were used. Results showed that this species has narrow ecological niche and is sensitive to habitat changes. Information layers determined as affecting variables on this species include slope, aspect, elevation, land form, Geology and climate. Results showed that 27.17% of Arasbaran biosphere reserve were suitable for Juniper. The suitable habitats were recognized to be in areas with elevation range of 330 to 1500 meters above sea level, 10 to 60 percent of slope, hillsides, mediterranean and semi-arid climates. The results of this research is suitable for sustainable management of forest ecosystems, reclamation and land protection.
