Field Notes
We felt happy because, we got to see the wonders of nature and we got to explore the world of science.We heard sticks crunching beneath our boots, and the peaceful sound of raindrops penetrating the foliage. We see the rows and rows of evergreens and birch trees. Dead leaves laid on the ground their final resting place. It smelled of fresh rain and sweet sap. We were surprised that in the small amount of land that we were given we found an eastern hemlock. However we weren't surprised that we didn't find a Hemlock Wooly Aphid. Our group had many debates on wether we found a Hemlock. So we did some more research and found out that we actually did find a hemlock.

Photos are of balsam fir; host to another invasive adelgid, the balsam woolly adelgid from Europe. Great photos, though!

Thank you!
