Ailanthus altissima (Tree-of-heaven): Ecology

Habitat: This tree is the most adaptable and pollution-tolerant tree available, becoming a pest in some areas because it propagates so readily from seed and by root suckers. In Washington D.C. there was once an ordinance prohibiting the planting of this tree within the city limits. It will grow in sterile soils and can even withstand its root area being submerged in salt water.

Diseases: This species is not susceptible to any serious diseases or insect pests and will withstand neglect.
Distribution: The tree-of-heaven is native to China and was introduced to the US in 1784. Hardy to zone 4, it is widely cultivated in Iowa urban areas and often escapes to grow on vacant lots and in waste areas.
