Field Notes
It's a sunny day and birds are chirping. I can see a fence surrounding the area that we are studying. I see the trees and bushes in the forest and the track and field.

Supporting Evidence

It had green, small, oval leaves with round, smooth edges and they had a thicker texture than regular leaves.

Each small cluster of leaves had one thorn. The stems grew in a zig-zag pattern with one thorn at each joint.

The leaves were 2 to 4 cm long and there was a bush with a dense, round top where they grew.

Comments

Your evidence is spectacular! Really impressive sketch, photos, and written evidence.

...and you even got an ant to pose for you!

Question for you - did you see barberry all along the fence, or just in that one spot? It doesn't look like it was planted, so how do you think it got there?
