Field Notes
From my field notes was that I found what we were looking for but we ran into problems like location and how much there was in this one area. We also found that there was dead leaves and branches that came off of the Japanese Knotweed. I can tell they are Japanese Knotweed leaves because they look like the ones on the rest of the Japanese Knotweed

Supporting Evidence

There are mostly baby leaves coming up from the ground that is producing more Japanese Knotweed I can tell it’s Japanese knotweed because the leaves look like the ones on the other Japanese knotweed.

We found about 7 dead leaves from Japanese knotweed that means that the Japanese knotweed is making new leaves and stems for next year I knew they were Japanese knotweed because it looked like the leaves on the other sets of Japanese knotweed
Photo of my evidence.
I can tell there is 1 new stem that is growing from Japanese Knotweed because the stem looks exactly like bamboo but smaller and has baby leaves on it exactly like the other Japanese Knotweed leaves.
