Other Site Characteristics

Site includes part of Venta River valley. Forests with Quercus robur, Tilia cordata and Ulmus glabra cover slopes and ravines at the river. Also dry coniferous forests and wet pine and spruce forests are found. Agricultural lands including calcareous grasslands occupy large areas in the site. Occasionally, transition mires and springs, sandstone outcrops and caves are found.

4.2 Quality and importance

Main qualifying features are Tilio-Acerion forests of slopes, screes and ravines (9180*) and Semi-natural dry grasslands and scrubland facies on calcareous substrates (6210); some meadows host significant population of Orchis mascula and also Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation (3260), Fennoscandian mineral-rich springs and spring fens (7160), also Bog woodland (91D0) and Transitional mires and quaking bogs (7140) and Western taiga (9010*). Qualifying species are Lampetra planeri, Cobitis taenia, Cottus gobio, Aspius aspius, Rhodeus seriaceus amarus, Salmo salar, Lutra lutra, Myotis dasycneme, Unio crassus. Venta River is significant feeding place for nationally rare bat species, including Myotis dasycneme. Significant for anadromous fishes of Annex II. Hosts large number of nationally rare plant and invertebrate species.
