Силинский лес, Natural monument and protected forest in Komsomolsk-on-Amur, Russia

The Silinsky Forest is a protected woodland in Komsomolsk-on-Amur that spans approximately 50 hectares and holds more than 400 species of vascular plants. The woodland ecosystem also supports rich fauna, including numerous bird and mammal species alongside various other animals.

The forest survived from the city's founding in 1932, though fires and clearing for vegetable plots reduced it; the central coniferous-broadleaf stand remained. In 1981 the city set aside this studied area as a natural arboretum under the Komsomolsk Reserve. On 24 May 1983 the city council made it a natural monument, and on 20 January 1997 Khabarovsk Krai decree No. 7 raised it to regional status.

The forest holds significance for local residents as a refuge where they can connect with nature near the city. It demonstrates how diverse plant and animal communities persist in an area shaped by industrial development.

The monument covers 50.76 hectares, with a 3 km fence and a 500 m buffer zone. The Silinka River lies 350 m west of the central artificial lake, dug in 1984 on the site of an old burn. The ground is flat first-terrace land with old channels and hollows, so wear waterproof footwear after rain.

In 2013, researchers found Neottia papilligera, a rare relict orchid of the Far East, on the territory. The forest also marks the northern limit of the range of many endemic and relict plants, and its artificial lake was created in 1984 on the site of a former burn.
