Invasive Species

I wasn’t having much luck at Emily Traphagen park finding new invasive species, so aside from autumn olive, i found the rest of these species at Highbanks Metro Park. I wasn’t having much luck but I think i found some!

Autumn olive is often recognized by their distinguished wavy leaves. Elaeagnus are among few nonlegumes that fix nitrogen in the soil by means of bacterial root nodules (Petrides).

Japanese Barberry (Berberis thunbergii)

Japanese barberry is recognized as a shrub with wedge shaped leaves that are not toothed, better look out because their thorny too! Their fruits are eaten by many birds, including ruffed grouse, bobwhite, and pheasants.

The leaves from privet are firm but not tough or leathery, and are slightly hairless. Their fruits are eaten by some song and game birds (Petrides).

Winged burning bush (Euonymus alatus)

A distinctive feature of winged burning bush, it the wing itself, it is a shrub or small tree with green 4 lined twigs with egg-shaped or elliptic, short-pointed, fine-toothed leaves. Their fruits are said to be poisonous to children.
