Due to tree-of-heaven being an invasive species, there is an interest in understanding how it changes the forest from germination to decay. This research aims to study the relationship between insects and the two tree species, tree-of-heaven (Ailanthus altissima) and tulip poplar (Liriodendron tulipifera). Comparing tree-of-heaven’s invertebrate interaction to a similar native species, tulip poplar, will give us a better understanding as to how its interactions will affect the ecology of the forest.
