Field Notes
I am happy that I found the species I needed to find. I was also happy to find that the species was not totally taking over the entire area around the quadrat. Unfortunately at some point the Japanese Knotweed will take over. I see trails, sand, and many trees. I hear cars because we are next to the road, and people talking. I smell wet soil, and wet leaves. I did not run in to any problems along the way.
Supporting Evidence
Photo of my evidence.
Leaves are simple and round a major sign of Japanese Knotweed. Also the leaves are somewhat narrow. Last but not least the leaves have no hairs on the underside of the leaf. these are all shown on the VitalSigns ID card.

Hollow stem inside of the plant that is anther strong point showing that this Japanese Knotweed. This plant still had liquid in the stem which proves it is alive. All shown on the VitalSigns ID card.

Bamboo style stem this is a very obvious but still important feature of finding Japanese Knotweed. The stem was arranged in a very easy to see zig-zag pattern. Last but not least the stem had large swollen joints. This was all shown on the VitalSigns ID card. This is how I know this is Japanese Knotweed
