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.

The bark of our hemlock, looked similar to that of an older specimen, with cracked brown bark.

I love your field notes! So descriptive :)

I am not an expert on hemlocks, but I think you found a similar species to hemlock, balsam fir. Balsam fir needles look a lot like hemlock needles with the 2 racing stripes, but they connect to the twig with a suction cup instead of a small stem. Your sketch shows a need with a short stem but your 3rd evidence photo shows needles attached that looks more like balsam fir. And the first photo shows a needle without a little stem.

Thank you, and yes I think your right. We should have considered other types of trees that look similar. It was really hard because we only had a little area to look at. Thank you for your input!

That's something we didn't think of! Great catch! Maybe ID cards for the Balsam Fir should be included in the mission so they don't get confused!
