Site description The 80-km stretch of the River Mura which flows through Slovenia. Seasonal flooding creates a characteristic landscape with numerous natural features, from gravel riverbanks to dense marshlands to old meanders along the lower stretch of the river, as well as huge alluvial forests. èrni log (1,200 ha) is the largest Alnus forest in central Europe, and is dense and uninhabited. Because of the danger of flooding, dykes have been built along the riverbanks. The Mura river meadows, wet grasslands, flood-plain and forests remain relatively intact, but cultivated fields and grasslands are intensively managed.

Key Biodiversity The site supports important breeding numbers of numerous species of European conservation concern that are typical of flooded forest, meadows, and riverbanks. The population densities of many species are high due to the relatively natural state of the alluvial forest habitats. Significant proportion (³1%) of national population breeding at site: Jynx torquilla (30-50 pairs). The site also holds nationally important numbers of breeding Ciconia ciconia and riverine forest passerines.
