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 decora The fruits (pomes) are bright red to orange-red and across. Showy mountain-ash is very similar to the closely related American mountain-ash ("Sorbus americana"). Like the American mountain-ash, the showy mountain-ash has odd-pinnately compound leaves and often large clusters of flowers and fruits. Showy mountain-ash can be distinguished by its shiny, sticky buds, and its slightly larger flowers and fruit. It is said to bloom a week earlier. It is often cultivated as an ornamental plant for its cold-hardiness, its attractive flowers, and its large clusters of small red berry-like pomes. The fruits are an important source of food for wildlife,
