Khosrov Forest State Reserve pear ("Pyrus"), rowan ("Sorbus"). The southern steep sunny and dry slopes are covered by juniper sparse forests. Caucasian oak ("Quercus macranthera") forests can be found at an altitude of 1600–2300 m above sea level, which are rather dense in Khosrov district of the reserve known as "Trchnaberd". Oak forests are accompanied by ash ("Fraxinus excelsior", "Fraxinus rotundifolia"), rowan ("Sorbus aucuparia"), pear ("Pyrus"), maple ("Acer") and others. Bushes are abundant in the forests, represented by different species of wayfaring tree ("Viburnum lantana"), honeysuckle ("Lonicera"), rose ("Rosa"), hawthorn ("Crataegus"). The vegetation in the forests is rich in grass (family "Poaceae" L.). Mountainous
Sorbus aucuparia be applied to other species in "Sorbus" subgenus "Sorbus", and mountain ash may be used for several other distantly related trees. The species is unrelated to the true ash trees (genus "Fraxinus"), which also carry pinnate leaves or the species "Eucalyptus regnans", also called mountain ash, native to Tasmania and Victoria in southeastern Australia. "S. aucuparia" was previously categorized as "Pyrus aucuparia". The author citation "Sorbus aucuparia" L. belongs to Carl Linnaeus. "Sorbus aucuparia" occurs as a tree or shrub that grows up to between 5 and 15 m in height. The crown is loose and roundish or irregularly shaped
