Field Notes
Field Notes Sketch

The temperature at 6:00pm is cooler than earlier today. We heard kids voices, traffic and birds. We noticed a sign that read: Caution: Poison Ivy! We used the quadrat vertically rather than horizontally on the ground.

Leaves are simple, with smooth edges. They are oval with some that look heart-shaped. We noticed that something seemed to being enjoying this leaf.

fascinating!

What is eating these leaves? Those grazing scars are not something I see frequently. Wow, if this is a place that is convenient for you to get back to frequently, it would be great to see if you could identify the grazing organism!
This looks like a pretty small plant. Were there other stands of F. japonica nearby? Or was it all alone?
Nice work.
