Located in North Khorasan Province, this 21309 ha area is situated in the west of Sarigol national park. The protection of this relatively intact region is aimed at protecting and improving its biodiversity. The mean annual precipitation and temperature of 275 mm and 12 C, respectively have resulted in a temperate semi-arid climate. Sarigol has high animal and biodiversity. Around 200 plant species including juniper, thorn, fig, walnut tree, willow, Rosa elymaitica, oleaster, cotoneaster, acanthofyllum, devil’s milk, thistle, iris, borage and primrose have been identified in the region.
