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.
These leaves are short and sword-shaped. They are long and narrow and could be mistaken for the giant reed. But after further research, the leaves are only a foot long while the leaves of a Phragmites is 1.5-2.0 meters long.

Furthermore, this is the seed top of a native Maine weed, and not a Giant Reed. This is because a Giant Reed's top is a large, drooping, mop end made of a couple hundred seeds. The cluster can be from 40 to 60 cm long while this weed's seed cluster is was only 10 cm at most.

Lastly, Phragmites australis can stand 6 meters tall in the proper conditions. They are easily spotted and need water to develop properly. As you can see, there is neither water or Giant Reeds in this photo.
