Field Notes
Supporting Evidence
Photo of my evidence.
I found Japanese Knotweed in this area. I know this is Japanese Knotweed because the stems have lines on them like all Japanese Knotweed has. I used the vital signs ID card to help me.

I know I found Japanese Knotweed because the soil that it is growing in is one of the Vital Signs Species ID Cards exemplars that were proven to grow in.

I know I found Japanese Knotweed because the dead leaves that I found were the shape of what the Vital Signs Species ID Cards says they are, except they are a light brown color because they are dead. The leaves are normally a light green, smooth and oval shaped leaf.
