Protocol Overview

1. Select a field site with eastern hemlock trees.
2. Identify a hemlock tree to examine closely. Mark your tree with flagging tape so others will not survey the same tree.
3. Take pictures to show that the tree is an eastern hemlock.
4. Search 10 branches that are at least 1 meter long for hemlock woolly adelgid.
5. Record whether you found or did not find hemlock woolly adelgid and take photos of evidence of hemlock woolly adelgid.
6. Scan the needles for hemlock elongate scale. If you think you find it, write "Elongate scale present" in the Field Notes section.
