Field Notes
The habitat was right on the edge of the forest and was on the side of the road where there was lots of rocks, weeds, and all around there was trees. It smelled like pine. I heard the cars going by on the road. It was also windy.
Supporting Evidence
Photo of my evidence.
This picture shows that the plant we found had an opposite branching pattern with oval shaped leaves , and so does the Japanese Barberry.
Photo of my evidence.
The Japanese Barberry has thorns on the stem that are near the berries and the leaves. The thorns are sharp and are about a half an inch long.

The Last evidence we found was the berries. They were oval, and were a red/ orange. For every berry stem the there are two or three berries on it.

Comments

Very nicely documented. I'm really interested in your research question. Were there any clues nearby that might explain how an invasive species was introduced?

Are you planning to leave the plant there to see what happens over time, or remove it?

Thanks for looking for invasive species and publishing such great quality data.

I plan to go back in the pond area early next year during spring and to see if any seeds have spread. For now I plan to leave the plant there but if I need samples or something like that I will take some seeds off but i intend on leaving the plant there.
