Why are there no animal species found only in the Ural Mountains?

There are no animal species found exclusively in the Ural Mountains primarily because of the range's low elevations and high accessibility. Unlike many high mountain ranges that act as isolated "islands" for endemic species, the Urals do not provide the geographic or environmental isolation necessary to foster unique, localized fauna.123

Consequently, the animal life in the Ural Mountains differs very little from that of the adjacent regions in eastern Europe and western Siberia. The range serves as a bridge rather than a barrier, allowing for the free movement of species across its landscape. While the mountains span diverse zones—from Arctic tundra to steppe—the wildlife found there, such as the brown bear, lynx, and various rodents, is consistent with the broader Eurasian landmass.14
