Field Notes
In our field notes, we were happy about finding a good spot to sample knotweed, and we wondered how the knotweed got there. We saw knotweed, and we heard cars in the distance, we smelt moist dirt. We knew we found the Knotweed because of what the plant looked like

Supporting Evidence

Our evidence is that we know what the knotweed looks like, so we knew that this had to be the knotweed based on our knowledge. We also know what it looks like because of the vital signs ID card. We know it was Knotweed because it has those white things on the top.

Our evidence is that we know where knotweed would be. By looking at where trees were because it is invasive and we knew to look at trees because of the Vital Signs ID, and as soon as we saw its bamboo look. We would immediately know it’s knotweed.

We know that we found it because we looked at the photos of knotweed on the Vital Signs ID card just in case. This was matched with one of the images we found. We knew it was Knotweed because of what the leaves looked like.
