Range and Habitat in Illinois
The non-native Tree-of-Heaven is native to China. It was introduced into the United States as an easy-to-grow landscape tree. It is occasional to locally common in most areas of Illinois, except the NW section of the state, where it is apparently uncommon (see Distribution Map). This tree is invasive and it is undoubtedly still spreading into new areas. Habitats include woodland edges and openings, thickets, riverbanks, vacant lots, landfills and dumps, gravelly back alleys, areas along roads and railways, fence rows, and urban waste areas. This tree is more common in urban areas than rural or natural areas; it is especially common in impoverished and poorly maintained areas of cities, where it is sometimes cultivated as a yard tree. Tree-of-Heaven is a pioneer species that prefers areas with a history of disturbance.
