The Czech Republic’s mix of forests, lowlands and alpine meadows supports a diverse mammal fauna. From urban edges to remote mountain slopes, local habitats shape which species you might encounter on a walk, a field trip, or a targeted survey.
There are 69 Mammals of the Czech Republic, ranging from Alpine marmot (svišť horský) to Yellow-necked mouse (plch žlutohrdlý). For each species the list is organized with Scientific name,Status (IUCN/CZ),Size (kg/cm) so you can compare taxonomy, conservation status and body measurements easily; you’ll find below.
Which species on the list need the most conservation attention in the Czech Republic?
Look at the Status (IUCN/CZ) column: species marked as Vulnerable, Endangered or Critically Endangered globally or on the national red list are highest priority. Many bat species and some larger carnivores show elevated concern locally, so use the status tags to identify which populations require monitoring or protection.
How can I use the scientific names and size data when observing mammals?
Scientific names remove ambiguity across languages and help you match sightings to field guides or databases, while Size (kg/cm) gives a quick check against measurements or photos to rule out similar species. Together with status info, these fields make the list practical for ID, reporting records, or planning follow-up research.

Images and Descriptions

European hedgehog (ježek)
Prickly nocturnal insectivore of gardens, hedgerows and farmland. Common across lowland Czechia; look for rolled spines at day and foraging adults at dusk. Populations declining due to roads and habitat loss.

European mole (krtek)
Fossorial insect-eater that creates conspicuous molehills in lawns, meadows and forests. Widespread and secretive; best spotted by fresh ridges and raised earth in spring and autumn.

Common shrew (rejsek obecný)
Tiny, high-metabolism insectivore of woodlands, hedgerows and grassland. Frequently trapped in pitfall surveys; active day and night and rarely seen alive because of rapid movements.

Pygmy shrew (rejsek nejmenší)
Small shrew of damp grassland, scrub and woodland edges. Elusive and insectivorous; informed searches near streams and wet meadows give the best chance to detect sound or traps.

Eurasian water shrew (rejsek vodní)
Semi-aquatic shrew hunting in and beside streams, ditches and ponds. Seen on banks or in mammal trapping; notable for water-repellent fur and swimming ability.

European beaver (bobr evropský)
Reintroduced and expanding in Czech rivers and reservoirs; recognizable by dams, lodges and flat tails. Active at dusk and night; significant ecosystem engineer improving wetland habitats.

Red squirrel (veverka obecná)

Edible dormouse (křeček srstnatý / plch velký)
Nocturnal, tree-dwelling dormouse of mature deciduous woodland and orchards. Known for long hibernation and cheek-pouch food caching; sometimes visits attics and bird-box surveys detect presence.

Hazel dormouse (plch zahradní)
Small arboreal dormouse of hedgerows and mixed woodland; prized by ecologists for its sensitivity to habitat fragmentation. Best found with nest-tube monitoring and nighttime surveys.

Garden dormouse (plch zahradní / Eliomys)

Raccoon dog (mývalovitý pes)
Introduced East Asian species now established in wetlands and reedbeds; travels long distances and is most active at night and twilight.
