Harvard Forest Ecologist,David Orwig, and Mentor Teacher, Kate Bennett, prepared a new group of teachers to get students out tracking the tiny Hemlock Woolly Adelgid, an insect that is causing a major shift in New England's forest right now.
Teachers practiced labelling study trees and measuring new growth of hemlock trees at their branch tips to record on the Harvard Forest field data sheets that their students will use at their schoolyards this fall.
Dr. Orwig showed teachers the thinning of the Hemlock trees at Harvard Forest that has occurred since the Woolly Adelgid arrived several years ago.
Teachers were able to see the new growth of black birch saplings beginning to replace the dying hemlocks. We hope they will bring back the message to their students that "the forest never doesn't change". As one species declines, another fills its place in the forest. Change is the one constant.
