Měkkýši přírodní rezervace Hutě a jejího okolí v CHKO Bílé Karpaty [Molluscs of the Hutě Nature Reserve and its surroundings in the White Carpathians PLA]

Abstract

The Hutě Nature Reserve is located in the central eastern part of the White Carpathians PLA, near the Žítková village. The reserve protects a preserved and topographically heterogeneous area composed of forest groves, meadows, pastures, and spring fens with a high diversity of submontane and thermophilic plant and animal assemblages. The species composition of molluscs (9 out of 10 ecological groups represented) consists mainly of woodland dwellers, which account for the majority of species diversity (30 spp.; 52%), followed by ubiquitous (9; 16%), hygrophilous (5; 9%), hygrophilous woodland dwellers (4; 7%), aquatic (4; 7%) and open-habitat dwellers (3; 5%). Vertigo moulinsiana (EN), internationally protected under Annex II of the EU Habitats Directive, Daudebardia brevipes (VU), Ambigolimax nyctelius (NT), Orcula dolium (NT) and Bythinella austriaca (NT) are species of conservation concern. To retain favourable habitat conservation status, the spring fens with V. moulinsiana occurrence must be managed extensively by grazing or mowing, while the forests must remain in a non-intervention regime.
