Other Naturalized or invasive species in our area.

These plants have been covered in earlier lectures and labs but these are also considered somewhat invasive, although some more so than others (Norway maple).

Norway maple is not native but has become naturalized. Box-elder has become naturalized outside of its native range (according to Farrar). There are many species of roses and some have escaped into the forest edge. Multiflora rose (Rosa multiflora) is one example.

Norway Maple Acer platanoides

Box-Elder or Manitoba maple Acer negundo (very aggressive but maybe not invasive)
