Ailanthus altissima (tree, shrub)

Ecology Distribution Management Info Impact Info References and Links Contacts

General Impact All over the United States, Ailanthus altissima has become a pest of agricultural, urban and forested areas. Seedlings and root suckers of A. altissima grow rapidly and spread prolifically and thus quickly out-compete many native species for sunlight and space. It also produces a toxin in its bark and leaves. As it accumulates in the soil, the toxin inhibits the growth of other plants. The root system is capable of damaging sewers and foundations.          Location Specific Impacts: Connecticut (United States (USA))   Agricultural Competition: Outcompetes native plants by releasing toxins into the soil and competes for basic nutrients.
