The pH value of it is 4.7-6.2. With a deep root system, it is a photophilous plant and can tolerate drought to a certain degree. Tiny forests ofChangbai Scotch Pine areoften found in regions of lower altitude, while in regions 1300 meters above sea level they are often found in mingled forests together with Korean pines and other trees.
