Field Notes
Our transect area-7 is full of both native and invasive species. For example, we have one invasive glossy buckthorn to the left side of our patch. It is large and it branches out on to the other transect sections to the left. There is one Asian bittersweet wrapped around an ash tree in the middle, and one “possible” purple loosestrife hidden behind a barrage of young pine saplings. Our area is extremely rocky and is filled with holes and tunnels underneath the rocks without any large amounts water or streams in the area. We have several weeds of different kinds and even one that looks like a young giant reed/Phragmites, but is simply a native Maine weed. Anywhere that isn’t filled with weeds is filled by grass, unable to be mowed due to overgrowing plants of different kinds. We used rulers, cameras, and our destructive ability to find, uproot, and collect data. We used a set mindset and a grid search pattern to completely search the area, making sure that we don’t miss any areas/plants. Though we have about two invasive species, our amount of native far outweighs our amount of invasive so I believe that the health isn’t too poor, but will definitely need help in the future to stop any further destruction from invasive species.
Supporting Evidence
Photo of my evidence.
Here is a photo of the native American Bittersweet wrapping around a native ash tree. Both of these plants are living in a symbiotic relationship.
Photo of my evidence.
Small, arrow-shaped leaves with jagged/toothed edges. These leaves have a sharp tapered end. These leaves are a vivid green with no other colors. An Asian Bittersweets leaves would be wider and darker, with little to no tapering at the end.
Photo of my evidence.
The leaves alternate from left to right down the stem. The stem of the vine is flexible and green out of the barky, larger stem of the plant. The stem/root of the Asian Bittersweet is of a papery and redder nature.

Nice work, I see the differences between the native and invasive.
