Field Notes
I was happy because we got to do fun science stuff outside of the school building. I saw some leaves, and some very calm waves in the water. I smelt fish and grass. I am surprised by what i didn't find because the pond looks like it would have all sorts of plants in/near it. A problem i ran into was that we didn't have the best area to place our quadrat.
Supporting Evidence
Photo of my evidence.
I think we did not find Oriental Bittersweet because there has been no complaints that this plant has harmed anyone in past and they haven't cut them down yet so this means what we found is not invasive so it is not Oriental Bittersweet.

Another reason why we think we did not find it is because what we found has not harmed the environment so there for it is not Oriental BItterswet.

One last reason why we think we didn't find Oriental Bittersweet is because this leaf is way to pointy. Oriental Bittersweet has round edges not pointy. And the leaf isn't glossy like an Oriental Bittersweet.

I thought you guys had great derscriptions! They were detailed and easy to understand. One thing that could improve your work is make sure your photos are in focus and there aren't any people or body parts in your picture. Reason being is they are a tad bit destracting! But otherwise great job and keep up the good work :)

I think you did a pretty good job overall. But in your supporting evidence you should have mentioned more about why it wasn't Oriental Bittersweet.
I know you said a little about the leaves and that was good so if you search for more invasive species and end up in the same situation (where you didn't find it) you should say more about about the parts of the plant not about how the plant is there. Just because the plant is still there doesn't mean that it isn't invasive.
But overall good work.

I agree with you that this is not Oriental bittersweet. Next time you could point out that you did not find a vine and that you did not find any red berries with yellow ovary walls.

Thanks for looking for bittersweet. It's easy to spot this time of year, especially if you look up into trees or along fences and telephone poles for its' yellow leaves and bright red berries. I'm seeing it everywhere, so am glad to see a "not found" observation in Sanford!

Great work getting all you photos and writing published. I think you could have used some of the data from the Oriental Bittersweet ID card to prove that the plant you found is not it.

Invasive species don't have to "harming" anyone, but they will do harm to the environment and surrounding plants if left unchecked.
