Site details
Site description: The Nanošèica river basin is situated in the lower Pivka valley near Postojna at the edge of a large depression. Habitats are relatively intact and undisturbed by man. The river has numerous meanders with well- preserved meadows, and small areas of reed and sedge. Pugled hill, in the middle of the site, supports relict remnants of neutral-soil beech Fagus forest. Because of the wet ground, extensive farming is possible only on the driest border of the site, and human settlement is concentrated here.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: An important site for breeding Crex crex. A total of 63 bird species have been recorded, among them 45 breeders and a further seven possible breeders. The site is also nationally important for birds on migration.

Threats
Summary of threats to biodiversity at KBA: Large cattle-farms sometimes pollute nearby waters with liquid manure. Agricultural improvement and drainage of wet land should be controlled. Intensive ornithological and entomological research is planned.
