Site description
The north-western ridge of the Dinaric mountains. A flat to hilly limestone area, after which the term `karst' was named, with a rich diversity of karst features such as caves, sink-holes, dolinas and canyons. Rocky and sparsely vegetated until the beginning of the 20th century, the area is now partly afforested (Pinus nigra). Land-use has been abandoned over vast areas which are now undergoing natural succession to shrubland and forest. The region is now a mosaic of dry and rocky meadows and pastures, shrublands in various stages of succession, and woods. There is a strong Mediterranean component to the flora and fauna.

Key biodiversity
Several species of European conservation concern (SPECs), typical of woodland, meadow and pasture, breed in important numbers, and numerous other SPECs breed in less significant numbers. Significant proportion (³1%) of national population breeding at site: Carduelis chloris (min. 500 pairs). Nationally, Karst is also notable as a wintering site for many species because of its favourable climate (low snow-cover, etc.).
