The area consists of diverse river habitats – from fast upper flow of Krka river with steep banks and few gravelbars, river lakes (Visovac lake) to brackish river mouth (including Prokljansko jezero). Krka and Cikola gorges are characterized by numerous high and extensive cliffs, rocks and screes. Along some part of its flow Krka river is surrounded with wet and dry meadows and arable land. Wetland habitats are well developed in shallow bays of Visovacko jezeo and at river Gudaca mouth. On a plateau above river xeric grasslands are well developed and hold the most important population of Calandra Lark in Croatia. Same parts of the plateau are covered with sub Mediterranean forest. Changes in traditional farming, unregulated recreational activities and tourism, excessive or illegal hunting outside the National Park, excessive water extraction and infrastructure development (impact of power lines and wind-parks) represent the main threats to birds in the area.
