Field Notes
It wasn’t very difficult to find, it was all over the trails by the pond by Weeks Road. That isn’t always a good thing though, for that means it has spread quickly on the trails. I knew it was Japanese Knotweed because it fit the vital signs description perfectly.

Supporting Evidence
Photo of my evidence.
These are Japanese Knotweed because they have the signature oval, smooth leaf shape, and the bamboo-like stem with swollen joints.
Photo of my evidence.
This is Japanese Knotweed, because it is next to a large patch of it, and it is just a smaller version. Ovular, smooth leaves, and little bamboo-ish stems with swollen joints.
