This range stretches approximately 1,200 kilometers and is known for its diverse ecosystems, including forests, grasslands, and wetlands. The mountains are home to various wildlife species, making them an important area for biodiversity. The Greater Khingan Mountains serve as a natural barrier between the Siberian Plain to the north and the Songnen Plain to the south.
