Field Notes
There were a lot of trees in the area that I was in. There were a lot of different plants that were all around me when I went. You could see woods and cars about 30-40 feet away. You could hear the cars going down the road and you could hear some animals like birds. I smelt like forest and a tiny bit of gasoline from the cars passing by.
Supporting Evidence
Photo of my evidence.
I do not think i found it because this plant is a different shape then the plants that i found at the study site. MAMW is also smooth while these are toothed.
Photo of my evidence.
Mile-a-minute weed might not be in my study site because mile-a-minute weed is a light green where this plant that i found is a darker green
Photo of my evidence.
This plant might not be in my study site because this plant is 7.5 cm. while MAMW(mile-a-minute weed) is 2-8cm.

this is very scientifically wonderful , thank you for sharing your beautiful information with me. I feel sooooo much smarter than I was 2 minutes ago.

great job ! u did a good job taking pictures of the plant . in the measuring picture


You did a great job of examining the plant you saw, comparing it to the notes about the plant you were looking for, and coming to a logical conclusion that the plant you found is NOT mile-a-minute vine.

Nice job guys!
