Kurils Nature Reserve (Russian: Курильский заповедник) (also Kurilsky) is a Russian 'zapovednik' (strict ecological reserve) covering the north and south portions of Kunashir Island, the largest and most southernmost of the Kuril Islands, which stretch between Hokkaido Island in Japan to the Kamchatka peninsula in the Russia Far East. It also covers two smaller islands nearby to the southeast. The area is one of the largest wintering sites for coastal seabirds. The reserve sits on a tectonically unstable location, and is one of two Russian national reserves (with Kronotsky Nature Reserve) that protects territory of active volcanoes. The reserve is situated in the Yuzhno-Kurilsky District of Sakhalin Oblast. The reserve was created in 1984, and covers an area of 65,364 ha (252.37 sq mi).
