Ailanthus, tree-of-heaven update, a northeast regional biological control project

Informally Refereed

Abstract

The tree-of-heaven (TOH), Ailanthus altissima (Mill.) Swingle (Sapindales: Simaroubaceae), is an invasive weed tree distributed throughout most of the continental United States. It is a hardy pioneer species that colonizes disturbed sites, such as road medians, rights-of-way, and forest settings. It produces allelopathic chemicals, millions of seeds, and sprouts back when cut, making it an extraordinarily good competitor, resulting in the displacement of native plant species. Herbicide treatments can provide short-term relief, but are expensive and nonsustainable.
