The Lužnice River and its floodplain are protected in the Horní Lužnice Nature Reserve (Southern Bohemia, Czech Republic). The floodplain has a relatively natural character. Altogether 21 aquatic mollusc species were found at 40 sites. Lymnaea stagnalis, Physa fontinalis, Segmentina nitida and Planorbarius corneus belonged among the most often recorded species. Endangered Pisidium globulare was found. Non-native molluscs were not recorded. Only minimal changes were documented after the first research of this reserve, which was done more than 10 years ago.

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.

Aquatic malacofauna of the Hrubý Jeseník Mountains, the Rychlebské hory Mountains, the Zlatohorská vrchovina Highlands and the Žulovská pahorkatina Highlands (Northern Moravia, Czech Republic) was investigated in 2000, 2001 and 2003. Altogether 26 species (17 gastropods, 9 bivalves) were found at 56 localities. Species Galba truncatula, Radix peregra s.str., Ancylus fluviatilis and P. casertanum, which often inhabit springs and smaller brooks, belong to the most common molluscs in this territory. Ponds and different water bodies originated by mining enrich aquatic malacofauna of this area by e.g., Lymnaea stagnalis, Gyraulus albus, G. crista, Hippeutis complanatus, Anodonta anatina or Musculium lacustre. The finding of Ferrissia clessiniana is the first record of this non-native mollusc in the territory of Northern Moravia. Water bodies in the Vidnavské mokřiny Wetlands Nature Reserve on the Czech-Poland frontier are inhabited by molluscan community with many species living in lowlands and this community is different in comparison with molluscan communities of the other investigated localities.

This paper brings the first malacological research of the proposal nature reserve Vrchlice Valley (Central Bohemia, Czech Republic) after hundred years. Altogether, 44 mollusc species have been recorded in a very diverse mosaic of floodplain forests, cliffs and meadows. Rare or locally important species Vertigo pusilla, Semilimax semilimax, Daudebardia rufa, Isognomostoma isognomostomos, Oxyloma elegans, Vitrea crystallina and Laciniaria plicata were recorded in the area of the reserve.

This paper brings a research of molluscan fauna of the Voděradské Bučiny, an important Nature Reserve near Jevany (Central Bohemia, Czech Republic). Altogether, 38 mollusc species have been recorded in the large complex of natural beech forest on the granite background. Rare woodland species Daudebradia rufa and Vertigo substriata were recorded here. Voděradské Bučiny reserve can be used as a model example of natural molluscan assemblage of acidic beech forest.

The results of a more than 50 years lasting malacological survey in the Mionší NNR are published here. The virgin forest of Mionší is one of the most important forest reserves in the Czech Republic and it presents the most preserved nature of the forest mountain habitats in the Beskydy Mts. Altogether, 62 mollusc species have been recorded there and we encountered 58 of them during 1998–2005. The molluscan fauna as a whole is characteristic for its high share of Carpathian species. Some of them reach a western limit of their occurrence there (e.g. Vestia gulo). The presence of virgin forest inhabitants (Macrogastra latestriata, Bulgarica cana, Acicula parcelineata) is of prime importance. Macrogastra latestriata, an index species of climatic Holocene optimum, has its largest population within the Czech Republic here.

Altogether, 78 mollusc species were recorded in the Hemže-Mýtkov Nature Reserve (East Bohemia, Czech Republic) during 2005–06. This locality harbours 32% of the total mollusc fauna of the Czech Republic at only 29 ha. This fairly high species richness corresponds to a high habitat diversity and species pool of the region that consists of a mixture of Alpine and Carpathian elements. Of prime conservation importance is a high share of rare and endangered species and species mostly having an isolated population there from the main distribution range. These species are East-Alpine Aegopis verticillus, Cochlodina commutata and Itala ornata, and the East-Alpine-Carpathian Bythinella austriaca. Carpathian species represents Faustina faustina. Except mentioned species there are several other rare and sensitive species such as Daudebardia brevipes, Perpolita petronella, Platyla polita, Pupilla sterri, Vertigo alpestris, and Vertigo antivertigo. Although, forest species prevailed, there were also representatives of other ecological groups such as synanthropic, steppe, water, and wetland species.

This paper brings a review of a long-term malacological survey of Peliny, an important Nature Reserve near Choceň town (East Bohemia, Czech Republic). Altogether, 50 mollusc species have been recorded during the last 100 years (representing 21% of the total Czech mollusc fauna). The isolated populations of the East-Alpine Cochlodina commutata, Itala ornata, and Pupilla sterrii were confirmed. The last mentioned species has a single site there within the East Bohemia. Rare woodland species Platyla polita, Daudebradia rufa, and Vertigo alpestris were recorded for the first time.

The headwaters of the Javorná River is situated in the northern part of the Jeseníky Landscape Protected Area (N Moravia), north of the Rejvíz National Nature Reserve. A population of the endemic Vestia ranojevici moravica was found in this locality in 1968, cca 70 km far from its known distribution range in the N Moravia. During the recent inventory of this site 48 mollusc species were found including four rare dendrophilous clausilids: Bulgarica cana, Vestia ranojevici moravica, Cochlodina orthostoma and Clausilia cruciata. The beech and scree forests of this locality represent the most preserved malacological site in the Hrubý Jeseník Mts which should be strongly protected.
