Basegi Nature Reserve is a Russian 'zapovednik' (strict nature reserve) along the Basegi Ridge, in the Middle Ural mountains. "Basegi" means "beautiful" in the local Urals dialect. It is relatively untouched by commercial use, and thus the area has scientific value as a "reference site" for spruce-fir forests of the Urals. It also supports spawning habitat for trout and grayling. The main rivers are the Usva River (northern border of nature reserve) and the Vilva River (southern border). There are also some small rivers, that have rapids typical of mountain rivers. The reserve is situated in the Gremyachinsk area of Perm Krai.
