Infraspecies

Invasive Species

Ailanthus altissima is a very aggressive plant, a prolific seed producer (up to 350,000 seeds in a year), grows rapidly, and can overrun native vegetation. It also produces toxins that prevent the establishment of other plant species. The root system is aggressive enough to cause damage to sewers and foundations.

Usage [3]  A yellow dye is obtained from the leaves; The leaves contain 12% tannin, quercetin, as well as isoquercetin, and the alkaloid linuthine; The leaves and wood are high in cellulose and are used in paper-making; The crushed leaves and flowers are insect-repellent; The plant parts, when steeped in water, are said to yield an insecticidal solution; An aqueous extract of the leaves contains a substance that is toxic to other tree seedlings; When plants are put into marshy areas they drain the soil and thereby remove mosquito breeding sites; The plants have extensive root systems and sucker freely, they can be used in soil-stabilization programmes; Since the plant is tolerant of soil pollution it can also be used in land reclamation schemes on old mine tips etc; Plants can be grown as a tall hedge; Wood - fairly hard, heavy, difficult to split, not durable, coarse grained. Though little used, except in poorer countries, the wood is suitable for cabinetry, cellulose manufacture, furniture, lumber, pulp, and woodwork. It is difficult to split but easy to work and polish. The wood is also used locally for charcoal and firewood; Yields of 20 cubic metres per hectare is possible for this light wood;
