Hike to Protect Hemlocks

December 1, 2021 - March 11, 2022

Join a series of guided walk and talks to learn to recognize and report hemlock woolly adelgid HWA- an invasive insect that kills hemlock trees. Hemlocks are an important tree species that provide many benefits for people and nature. Detecting the presence of HWA early on provides enough time to protect infested trees and helps to stop the spread to new areas.  To help raise awareness, and encourage community members to get involved, a series of guided hikes will be held each month beginning in December through March. Participants will learn how to survey for HWA and report observations using their smartphone through a free mobile application called iMapInvasives-a community science tool.

Prior to attending, participants should follow these steps:
