Field Notes
Day 1: When we thought found the Tsuga Canadensis (the Eastern Hemlock) we were happy because the Tsuga Canadensis is a native species and it had not yet been taken over by an invasive species. We all thought that the tree would be smaller than it was but the species card said that the tree could grow up to be 30 meters tall! Around the area of the tree it smelled like pine but if you go too far away from the tree than the smell starts to fade. We were right near the highway so we heard a lot of cars going by but the cars weren't enough to cover up the the songs of the birds on nearby trees. Day 2: When we were outside we realized that the temperature had changed a lot over the weekend but the tree didn't look that different at all. There was one big problem that we ran into while trying identify the tree. The problem was that it was really difficult to get to the middle of the tree to get a look at the bark. It was difficult because when we tried to get to the middle of the tree we would get all scraped up and there wasn't a big opening in the branch's so if we didn't want to get scraped up than we had to walk around all the trees to a bigger opening.

Supporting Evidence

The card said that a older Eastern Hemlock bark would have grayish brown, scaly and cracked. That's what the bark looked like on this tree. The tree was on the older side and our group thinks that because the tree was very tall.

The needles on the Eastern Hemlock were about 1cm long just like the card said they would. The needles also have 2 white parallel lines running along down the middle of the needle. The top of the needle is shiny and a shade of dark green but the bottom of the needle looks a lot lighter in color.

The card said that in the spring the Eastern Hemlock will have "flowers" (pine cones). The Eastern Hemlock did not have any "flowers" when we went out there. There were no "flowers" on the Eastern Hemlock's branch's but that is good since we went outside to do our investigation in the fall.

nice field notes.

Thank you so much for commenting on our work we worked very hard. Also you came to our school to teach us about invasive species just a few says ago:)

Your photos of the hemlock twig leaves no doubt that you have correctly identified the tree. You can still find remnants of last spring's pollen buds on many hemlocks this fall; it was a year of abundance for conifer pollen (and cones).
