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
Burrington Combe as a Site of Special Scientific Interest in 1952. The calcareous grasslands support a diverse flora which includes Salad burnet ("Sanguisorba minor"), Knapweed ("Centaurea scabiosa" and "Centaurea nigra"), Rock-rose ("Helianthemum nummularium") and Wild thyme ("Thymus praecox"). On the higher, more acidic, slopes Goldenrod ("Solidago virgaurea"), Wood sage ("Teucrium scorodonia") and Common Bent ("Agrostis capillaris") can be found. There are also scrub plants including Hawthorn ("Crataegus monogyna"), Mountain ash ("Sorbus aucuparia"), gorse ("Ulex europaeus") and Elder ("Sambucus nigra"). Several of the caves support bat populations. Geologically it is recognised as a fluvial karst feature which partly intersects a buried and filled
