On the southern slope of Damavand, there are remnants of wild pistachia trees (Pistacia atlantica). Along its riversides different kinds of Salix trees like willow (Salix acomphylla) and oleaster (Elaeagnus angustifolia) are found. Greek juniper (Juniperus excelsa) is common in the higher altitudes. On northern slopes, because of higher humidity, there are wild oak, beech and hazel trees like: Persian Oak (Quercus macranthera), Eastern Hornbean (Carpinus orientalis), and Oriental beech (Fagus orientalis). There are also many wild flowers such as mountain tulip (Tulipa montana) and Persian stone cress (Aethionema grandiflorum). At higher altitudes, shrubs tend to be sphere and cushion like, examples are : Astragalus species (Astragalus microcephalus), mountain sainfoin (Onobrychis cornuta) and prickly (Acantholimon erinaceum). Different kinds of grasses complete this alpine scene.
