Field Notes
For our native and invasive species study in science, our class split into 8 groups each with a 5x5 meter plot of land to study. All plots for the different groups were along the same transect line, side by side. The first morning we went out was warm but not so much so that you would be sweating, and the last morning we went out it was about 56° and very cloudy. Yet each time, particularly the first day you could more clearly see the line of shade created by taller shrubs and trees along the end of the forest where the plants had started to thin out some. Going out and looking at our land plot we immediately saw that the area was completely crowded and filled still with summer green shrubs, and tree leaves, but you also see straight up that one species, in particular, is most common in the area. That plant is Glossy Buckthorn invasive species to the area. The Buckthorn is growing considerably out of control crowding, suffocating, and killing the native plants, blocking them from getting to the surface and the sun. Some of the trees in the area are ash, white pine, and red oak, sadly many of these trees aren’t able to grow up and out of the Buckthorn as it crowds all around them. In one area to the left of the plot, you can see that a white pine grows but many of its branches are being pushed to the ground and even completely cut off from the tree, killing the entire branch. Though the Glossy Buckthorn has almost completely taken over the area I think with the right measures and time spent wisely it is still possible to fight back against this invasive species and save the native plants in the area.

Supporting Evidence

This plant is not the Oriental (Asian) Bittersweet because it has woody bark and is more of a shrub, growing upwards, unlike the Bittersweet which is more a vine that climbs and wraps around other plants.

Alike to the Bittersweet, this plant has 5-13cm long leaves which are finely toothed and placed going alternatively up the branches.

This plant is not the bittersweet which as a vine climbs and wraps around other plants most likely killing plants eventually, but this shrub is not climbing nor wrapped around anything.
