Field Notes
On April 14, 2015, the students of Massabesic Middle School observed the trees on their campus. These trees included; red pine, pitch pine, northern red oak and white oak, American beech, and Eastern Hemlock. They were looking for red pine for traces of the infamous red pine scale, and for traces of the insect hemlock wooly adelgid, both of these being harmful to their corresponding trees. The students observed the oak and beech species because they were interested in the marcesence trait of the trees, a special trait of the tree that allows it to keep its leaves over winter, while also losing some. A Deciduous/Coniferous Tree mixture. These students are very dedicated to the finding of these trees because in the month of November, they worked very hard to inform the public about these invasive insects, and how they could help to keep their trees healthy.

Supporting Evidence
Photo of my evidence.
This small branch piece was collected from the same Eastern Hemlock that was previously mentioned. The entire branch was thoroughly examined and there was no evidence of small white formations, or any hint of deformation. This tree was perfectly healthy, and it is believed there is no invasion by the Hemlock Wooly Adelgid.
Photo of my evidence.
This is a shot of the same Hemlock tree's bark. As you can see, there are no visible damages to the bark or any signs that lead us to think that Hemlock Woolly Adelgid is present, and because of this, we can conclude that Hemlock Woolly Adelgid is not present on the bark, or in the tree.

Glad to hear you didn't find any HWA and thanks for contributing to the field mission!


I'm also glad that we didn't find HWA as well! Good thing our tree is very healthy!
