Mountain Birch

Among the many tree species on Changbai Mountain, the mountain birch stands out as elegant and refined, adding splendor to the vast forest.

In late autumn, as we drive up the southern slope of Heaven Lake, passing through dense coniferous forests, we reach the upper part of the 1890-meter basalt plateau — Laolonggang. Looking out from the mountaintop: Laolonggang undulates like a coiling black dragon, its head raised and tail swaying, seemingly ready to soar through the clouds. This is also where the Changbai Mountain volcanic cone lies. A marvelous sight unfolds: patches of low, sparse mountain birch forests stand majestically on the mountainsides, ancient and weathered. As the altitude increases, the degree of trunk distortion becomes more pronounced. At higher elevations, the trees stand less than one meter tall. The once graceful and upright mountain birches are twisted in countless ways, hugging the ground or growing semi-prostrate with remarkable resilience. Their branches, bent uniformly southeastward by the fierce high-altitude winds, resemble elderly people weighed down by life’s hardships. Yet their crowns reach resolutely upward — impervious to freezing cold or howling gales. When an old tree dies, new green shoots emerge from others, demonstrating an indomitable vitality.

The mountain birch’s unique existence as the upper-limit tree species of Changbai Mountain’s forests is truly rare, resulting from the harsh alpine climate and soil conditions. At altitudes between 1800 and 2000 meters, steep slopes, low temperatures, coupled with strong alpine winds and prolonged snow and rain erosion, make it nearly impossible for most trees to survive, leaving them almost extinct. Only the mountain birch thrives in this extreme environment. They form the only pure forest of a single tree species at the summit of Changbai Mountain — short in stature but mighty in presence. With extraordinary resilience, they cling tenaciously to life, miraculously maintaining their evergreen nature. The mountain birch belt represents a unique combination of alpine tundra and forest elements, where distinct vegetation types intermingle. Rhododendron chrysanthum, a key shrub here, thrives alongside the birches. In spring and summer, when mist shrouds the mountains, the birch groves remain cool, damp, and shadowy, densely covered with fragrant shrubs and blooming flowers. Fallen trees, either naturally dead or struck by lightning, are tightly wrapped in moss. Every July and August, this area serves as a summer retreat for wildlife such as sika deer, black bears, and wild boars. Even more astonishingly, in the transitional zones between coniferous and mountain birch forests, clusters of pine and birch trees grow intertwined — their roots connected, branches entwined, embracing each other like loving couples in a breathtaking display known as the “Pine-Birch Love” scenic belt. It evokes the feeling that “even the beauty of Xi Shi would be jealous, while their noble purity defies the heavens.”
