Field Notes
This week we went outside on the edge of a paved road of a developed area outside the middle to research and take pictures of invasive species. When we went out it was about 10 in the morning and warm but not to hot, and got hotter throughout the day. The ground was moist because our area was shaded by tall trees probably Pine. There were 9 groups in our class and we all got a 5 by 5 meter area marked by flags, and we had to find and not find an invasive species. Half of our area's ground was covered in rocks and half was not which was different from all of the other groups because there ground was all covered in rocks. I was trying to find Frangula alnus or more commonly known as Glossy buckthorn which I was successful in finding, Although I only found a small bush of it in our area which is a good thing because it is invasive and has no spread that much yet. When I was looking for Glossy buckthorn I found a large bundle of another plant taking up a lot of our area that looked like Glossy buckthorn but I soon realized it was not. I also did look for Japanese barberry and did not find that. Our group also found a small bundle of Goldenrod in only one part of the area not taking up much of the space. We also looked for Asian bittersweet but did not find it. I did see plants growing and wrapping around other plants but was no able to identify it. This shows that there were many invasive species in our area. I did however see various native plant like many normal Pine trees.

Glad you could only find one small plant. Probably if that area was cleared of forest you would see much more buckthorn.
