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.

The Poledňana Nature Reserve is located in the northeastern part of the Beskydy PLA, close to Staré Hamry town. The subject of protection are old growth forests with natural-like tree composition. During the survey in 2021, 43 species (42 terrestrial and one aquatic) of gastropods were recorded. The species composition consists predominantly of woodland dwellers (28 spp.; 65%) followed by eurytopic (5; 12%), hygrophilous woodland dwellers (4; 12%), hygrophilous (3; 7%), strongly hygrophilous (1; 2%) and one (2%) aquatic species. Endangered Bulgarica cana, indicating high conservation value of local forest fragment, vulnerable Daudebardia brevipes, Eucobresia nivalis, Vitrea transsylvanica, nearly threatened Bielzia coerulans, Bythinella austriaca and Vestia turgida are species of conservation importance. There is need to preserve non-interventional regime in the most valuable parts to retain and to establish favorable habitat conservation status. The tree composition in spruce-dominated areas should be gradually changed towards natural composition.

Mollusc fauna of the Babinské louky Nature Monument in the České středohoří Protected Lanscape Area in North Bohemia has been supplemented and summarized. During the recent monitoring in 2021, 36 land snails and four aquatic species were recorded. This reserve mainly protects the famous orchid meadows, however, it also includes a number of other habitats, including forests. The local malacofauna is therefore relatively rich. There are strictly forest species (Isognomostoma isognomostomos, Merdigera obscura), species of open habitats (Vertigo pygmaea), hygrophilous species (Succinella oblonga) or boreomontane species (Vertigo substriata) living side by side.

A floodplain of the Lužnice river at the Czech-Austrian border is protected by the Krabonošská niva Nature Reserve (Southern Bohemia, Czech Republic). This floodplain has a relatively natural character and, in addition to the Lužnice river, there is a high diversity of habitats at various stages of succession such as oxbows, pools and temporary wetlands. Altogether 20 species were found at 15 sites studied in 2021. Common and widespread gastropods Lymnaea stagnalis, Segmentina nitida and Planorbarius corneus belonged among the most often recorded species. Endangered Pisidium globulare was found at two sites, and only one non-native species Physa acuta was recorded. Molluscan assemblages are very similar to the assemblages of the neighboring Horní Lužnice Nature Reserve.

The available data on the present distribution of Cepaea nemoralis in Ukraine, Belarus and the European part of Russia, the history and possible ways of penetration of this species into various parts of Eastern Europe, as well as the colour and banding polymorphism of its shells are analyzed. It has been suggested that the process of rapid spreading of C. nemoralis in the three compared Eastern European countries began at approximately the same time (late 20th – early 21st centuries) and that it may be caused by active and practically uncontrolled importation of seedlings from other European countries, as well as by global climate change, which can contribute to better survival of snails outside their natural range. Despite the possible initial limitation of the phenotypic and genetic diversity associated with the accidental transfer of a limited number of individuals, in the Eastern European colonies, in general, a fairly large variety of the inherited traits of the shell colouration remains. This concerns, first of all, the polymorphism in the shell ground colour (yellow, pink, less often brown) and the main variants of the shell banding (unbanded, mid-banded, five-banded, less often three-banded).

This paper presents important faunistic records including location data with all details conducted in the Czech and Slovak Republics during 2020. Four new non-native species, Arion intermedius, Ambigolimax valentianus, Clathrocaspia knipowitschii and Krynickillus melanocephalus, were recorded outdoors in Slovakia. Radix lagotis was genetically confirmed for the first time from several sites in the Czech Republic and Slovakia. Corbicula fluminea, recorded in Moravia for the first time in 2018, was found in another river, ca 50 km far from the first occurrence. Cepaea nemoralis, recorded in Slovakia for the first time in 2015, seems to have started spreading. New sites of Cornu aspersum were noticed in Prague and Bratislava; for the first time it was also found in Brno. There are also new records of several endangered species, e.g. Vertigo moulinsiana, Pisidium hibernicum, P. globulare, and Pseudanodonta complanata, presented.

Mollusc fauna of the Prokopské údolí Nature Reserve in Prague (Czech Republic) has been revised. The current research follows up on the monitoring that took place there at five-year intervals in the years 1984–2009. In the 1980s, 43 land snail and seven aquatic species were recorded, while in 2020 the list included 56 land snail and three aquatic species. Although the reserve is considered to be one of the best examined areas in the capital city, remarkable findings are presented, such as a viable population of the critically endangered Helicopsis striata, a new locality of the internationally protected Vertigo angustior, and a recent distant spread of the rare snail Zebrina detrita. Notable trends in the development of local malacofauna in the last four decades are discussed.

A specimen of the clausiliid snail Pontophaedusa funiculum (Mousson, 1856) was kept alive for 15 years after it was collected as an adult. This is the longest direct observation of the lifespan in the Clausiliidae, and one of the longest in all land snails.

Several xeric sites in the Karlovy Vary Region, mainly along railways, were surveyed for thermophilic snails of open habitats in 2019 and 2020. Two localities of Euomphalia strigella (Draparnaud, 1801), 13 localities of Monacha cartusiana (O. F. Müller, 1774) and two localities of Xerolenta obvia (Menke, 1828) were found. These three species are all new for the region. The locality of Tři Sekery (665 m a.s.l.) represents the altitudinal maximum of M. cartusiana in Czechia. Although the two sites with Xerolenta obvia were secondary; relatively high densities may suggest that these populations were established in this regions some time ago.

Mollusc fauna of three protected areas in the capital of the Czech Republic, Prague, was revised after 25 years (Hvězda Game Reserve, Petřín) or studied for the first time (Vyšehrad). In total, 56 molluscs species were found and the survival of endangered species Vertigo angustior and Nesovitrea petronella in the Hvězda Game Reserve was verified. Generally, some sensitive species in well-preserved localities are being replaced by weed species, including non-indigenous ones such as the invasive Arion vulgaris, and the southern element Monacha cartusiana. On the other hand, some woodland species such as Arianta arbustorum, Urticicola umbrosus, Eucobresia diaphana, Arion silvaticus and Lehmannia marginata apparently spread in Prague.
