Field Notes
The day we went outside to look for invasive species the sun was out and it was hot and humid. The time was around 2:00pm. Each group was assigned to a 5 by 5 meter section that was across the road from the school. The site was in a developed area with a parking lot and a paved road. In our site there was also a trail leading farther into the forest. We had the choice to try and find one of these three invasive species, glossy buckthorn, phragmites and Asian bittersweet, I chose phragmites. I had found phragmites but it wasn’t in my section. Each section was divided with flags. The area that the phragmites was in a more watery area and father down the road near the baseball field. In our section the grass was shaded by a tree. We did find glossy buckthorn that took about one fourth of our section and was about 10 feet high. To the left of the glossy buckthorn there was little weeds with yellow and white flowers that we could not identify. They spread over most of the area. Further into the woods in our area there was little skinny trees and little weeds all over, most that did have the little white and yellow flowers. We did not find any other invasive species in our area. So for now there was only one invasive species in our area (glossy buckthorn) and I don’t think it will spread rapidly and doesn’t seem to be taking over much of the area.
Supporting Evidence

The leaves on the plant were glossy and smooth with wavy edges just like the Glossy Buckthorn. They also had the color dark green.

The bark on the plant was thin and grey brown. It also had little white lenticels which are pores, just like the Glossy Buckthorn.

The alternate leaves on the branches were measured with a ruler and it shows that they are 3-6cm long.

Phragmites can withstand growing in wetter areas than glossy buckthorn.
