Bolon Nature Reserve (Russian: Болоньский заповедник) (also Bolon'sky) is the oldest Russian 'zapovednik' (strict ecological reserve) in the Russian Far East. It is located on the Middle Amur River lowlands adjacent to the south-west of Lake Bolon. The reserve covers the wetlands of international importance. Large numbers of migratory waterfowl use the area for nesting and stopovers on long flights. The reserve is situated half way between the city of Khabarovsk and Komsomolsk-on-Amur, in the Amursky District of Khabarovsk Krai. The reserve was created in 1997, and covers an area of 100,000 ha (390 sq mi).
