Common Name: Manchurian Ash

General Information

Fraxinus mandshurica is a deciduous tree that can grow up to 30 metres tall[]. The bole is usually up to 100cm in diameter, occasionally reaching 200cm[].
An important timber species, it is extensively harvested from the wild for local use and for trade. The tree is grown as an ornamental, there are some named varieties[]..
Fraxinus mandshurica is an important source of timber and has been extensively harvested in Russia and China and is is clearly under threat in Russia and in need of conservation management in both Russia and China. Nevertheless, given its overall distribution range, its abundance in Japan, The Republic of Korea and The People's Republic of Korea, and its ability to regenerate in degraded forests, overall this species is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2018)[].

Cultivation Details

Fraxinus mandshurica is a moderately cold-hardy plant, able to tolerate temperatures down to around -20°c when fully dormant. The young growth in spring, however, is very susceptible to damage by frosts and, in areas that are prone to late frosts, the plants are often badly damaged[].
Grows best in a sunny position, though tolerant of light shade[]. Although adult trees require a sunny position, seedlings can naturally regenerate under a forest canopy[]. Plants are tolerant of seasonal inundation of the soil - seedlings exhibit a high tolerance of soil flooding with enhanced stem growth and formation of sprouts, adventitious roots and aerenchyma tissues[].
Fraxinus mandshurica is a major host of the emerald ash borer, which does not cause damage to this tree species but has become a major pest of the Ash species in N. America, devastating whole populations and killing millions of trees there[].
Fraxinus mandshurica is not susceptible to ash dieback caused by the fungus Hymenocscyphus fraxieus[].
A dioecious species, both male and female forms need to be grown if seed is required[].

Edible Uses

None known

Medicinal

The plant is used in traditional medicine.

Agroforestry Uses:

Fraxinus species in general are gross feeders with an extensive, fibrous root system, which makes transplanting easy, but means that other species will often not grow well if planted nearby, especially if they are shallow rooted[],

Other Uses

An attractive wood, it is light in weight, durable. An important source of timber used for veneer, boats, musical instruments, furniture, sports equipment and small speciality wood items[, ].
The wood is used for fuel and makes a good charcoal[].
