Common (Translated Scientific) Name: Tree-of-Heaven Ruderal Forest

Colloquial Name: Ruderal Tree-of-Heaven Forest

Hierarchy Level:  Association

Type Concept: This forest association generally occurs on nutrient-rich substrates, in disturbed situations on slopes, urban abandoned lands, and on rocky limestone slopes, in association with a wide variety of other exotic species and generalist native species. There are floodplain forests in which invasive exotic Ailanthus altissima makes up 25-50% of the canopy; with other associated canopy species of Fraxinus pennsylvanica and Acer saccharinum. At this time, these forests are treated as D-ranked examples of native types.
