Abstract
The mollusc fauna of the White Carpathians Protected Landscape Area (PLA) has been
neglected for a long time. This situation changed in 1996 by including the PLA into the
worldwide network of UNESCO Biosphere Reserves. Many surveys have since been carried
out and the knowledge about this area has been improved. This atlas provides a
comprehensive overview of all land snail species recorded in the PLA.
A total of 431 sites were sampled throughout the PLA, covering a variety of habitat types.
Altogether, 104 snail species were found, which represents nearly two-thirds of the whole
land snail fauna of the Czech Republic. This is related to a broad habitat diversity in the PLA
with many preserved areas of high conservation value. Many of the recorded species are
listed in the Czech Red list of threatened invertebrates, including Bulgarica cana, Vitrea
transsylvanica and Daudebardia brevipes (Endangered) and Vertigo moulinsiana (Critically
Endangered). Moreover, V. moulinsiana and V. angustior are covered by the European
Natura 2000 network.
Most of the White Carpathian snail fauna is formed by forest species inhabititng in hight
numbers many preserved forest sites. In contrast, the large area of meadows is inhabited by
a few common species, probably because these mesic meadows occur on deep, originally
forest soils, which have lost calcium carbonate due to leaching. Nevertheless, on a fine scale,
the Carpathian bedrock flysch is one of the most variable types of bedrock. Landslides, which
are typical of it, have formed the White Carpathian meadows into a very diverse landscape.
Small skeletal patches with exposed calcareous bedrock enrich the malacofauna of meadows
by hosting typical xerothermic and steppe species which usually inhabit sites on limestone
substrates. Another situation in which carbonate substrates can reach the surface, are tufaforming
spring fens, which can support exceptionally species-rich communities of many rare
marshland and open-country species.
