Field Notes
The days of observation were moderately warm with some breezes and rain. It was mostly sunny and got cloudier as the days went by. On the edge of a paved road, multiple 5m by 5m sections were marked with flags. Rocks covered the ground that then sloped up to a slight hill. The goal was to find glossy (or alder) buckthorn and Asian (or oriental) bittersweet in our section, and while we found these, we also encountered purple loosestrife. Many native plants including white pine, elm, and ash plants were found throughout the area. We found an Asian bittersweet vine attacking a small ash tree. It rose out of the ground and leaned over to wrap around the trunk. The vine was brown, and wood-like, showing it is older. I suspect the vine has been there for some time. Several other vines were also found reaching toward the same plant;I assume the first vine led the others toward the tree. The ash tree and the vines took up about ⅓ of the width of the space, toward the right side close to the road. Glossy buckthorn was found behind a young elm tree, on the left, growing up out of the hill and shaded by larger trees. A close up sketch of a stem and two leaves was drawn. It did not have any berries and has an alternate branching pattern. With its height and width, I speculate it must’ve been present in the near past. A very small, young purple loosestrife was hidden behind a young maple tree in the back of the section, where the hill started to rise, shaded by bigger plants. Multiple red leaves were whorled throughout. All in all, I think that the health of this section was once better, and has been/ is being overtaken by invasive species.

Supporting Evidence
Photo of my evidence.
Toothed leaves, but are coarsely toothed unlike the Asian bittersweet. Also, the leaves have a fuzzy texture, not found with the bittersweet.
Photo of my evidence.
Not growing on a support, not a vine like the Asian bittersweet. Although, the stem and branches are a wood-like, but not bumpy like an Asian bittersweet.
Photo of my evidence.
No bright red red fruit with yellow skins common after August. And, a common alternate branching pattern is shown.
