Site description A range of hills, composed of limestone, dolomite and sandstone, that are part of the Western Carpathians. Forest covers the central part of the IBA, consisting of Fagus at higher altitudes, Quercus at lower altitudes and Pinus at the forest edge. Mesophile meadows, arable land, orchards and vineyards occur in the foothills. Due to substrate type, altitude and southerly aspect the IBA supports plant and animal communities typical of warmer areas.

Key Biodiversity Also important for forest- and scrub-nesting species including Pernis apivorus, Jynx torquilla, Dendrocopos medius, Picus canus, Sylvia nisoria, Phoenicurus phoenicurus and Lanius collurio. Breeding species of global conservation concern that do not meet IBA criteria: Crex crex.
