Field Notes
For our native and invasive species study in science, our class split into 8 groups each with a 5x5 meter plot of land to study. All plots for the different groups were along the same transect line, side by side. The first morning we went out was warm but not so much so that you would be sweating, and the last morning we went out it was about 56° and very cloudy. Yet each time, particularly the first day you could more clearly see the line of shade created by taller shrubs and trees along the end of the forest where the plants had started to thin out some. Going out and looking at our land plot we immediately saw that the area was completely crowded and filled still with summer green shrubs, and tree leaves, but you also see straight up that one species, in particular, is most common in the area. That plant is Glossy Buckthorn invasive species to the area. The Buckthorn is growing considerably out of control crowding, suffocating, and killing the native plants, blocking them from getting to the surface and the sun. Some of the trees in the area are ash, white pine, and red oak, sadly many of these trees aren’t able to grow up and out of the Buckthorn as it crowds all around them. In one area to the left of the plot, you can see that a white pine grows but many of its branches are being pushed to the ground and even completely cut off from the tree, killing the entire branch. Though the Glossy Buckthorn has almost completely taken over the area I think with the right measures and time spent wisely it is still possible to fight back against this invasive species and save the native plants in the area.

Supporting Evidence

This is the White pine because it has flexible blue-green needles

This tree also has a very straight trunk with branches in a whorled pattern going up.

For this tree, there are 5 needles per bunch. If you look close at the top left area of the bunch you'll see a pine needle that looks like it might be splitting at the top but it is actually two needles making 5 in total. This is quite an important characteristic of the White pine.

your pictures were super clear, I LOVED them. Its good that you clarified the five needles.

Looks like you found a very healthy white pine. I hope it stays that way and your invader, glossy buckthorn, can be thwarted.
