There are no species strictly endemic to San Marino.
Note the country is tiny and sits inside the Central Apennines. Endemic species form where populations are isolated for long times or where unique habitats exist. San Marino shares the same hills, soils, and climate with neighboring Italian regions, so no animals or plants are known to occur only inside its political borders.
Understand that endemism is a biological, not a political, label. Scientific databases and national red lists record endemics by their natural ranges. The Central Apennines do host true endemics — for example, the Marsican brown bear (Ursus arctos marsicanus) and the Abruzzo chamois (Rupicapra pyrenaica ornata) — but those species have ranges in larger Italian protected areas, not confined to San Marino. Small countries like San Marino rarely contain unique species because they lack large, isolated, or highly distinct habitats needed for new species to evolve.
Explore nearby and related categories instead. Look at endemics of the Central Apennines and the wider Italian Peninsula, regional endemic plants and orchids, and the list of protected species found in San Marino (raptors, bats, and Mediterranean scrub flora). For most readers, those categories give the best answers to questions about San Marino’s wildlife and conservation.
