The ash is distributed in North Korea, Japan, Russia, and Shaanxi, Gansu, Hubei, Northeast, and North China. It grows in areas ranging from 700 to 2,100 meters above sea level. It is generally grown in hillsides or in valleys. Mountainous areas have not yet been cultivated by artificial introduction.
In China, ash is mainly distributed in the eastern part of Daxing'anling in Heilongjiang Province in the northeast of China and Xiaoxing'anling in Jilin and Changbai Mountain in Jilin. It is also distributed to the Qianshan Mountains in Liaoning and the Yanshan Mountains in Hebei, as well as parts of Henan, Shanxi, Shaanxi and Gansu. .
It has scientific significance for studying the Tertiary flora and the Quaternary glacial climate. Fraxinus mandshurica is an ancient remnant plant. Although the distribution area is relatively wide, it is mostly scattered, and the number is decreasing due to over-cutting. At present, large trees are rare. Nature reserves (such as Changbai Mountain) have been built in only a few areas in the distribution area, and there are no specific protection measures in most areas. It is recommended that the relevant departments select appropriate sites and forests, establish protection points, protect existing large trees, and breed seedlings to expand afforestation area.
Harbin, Changchun, Shenyang, Beijing and other places have been introduced and cultivated.
