Embracing Tree Health Monitoring

Michigan’s Sentinel
Tree Network

The “Eyes on the Forest” program relies on volunteers like you to monitor Sentinel Trees across the state for signs of invasive forest pests. Read on to learn how you can make a difference.


To keep these unwanted pests out of Michigan we need help from people like you to be part of a network of volunteers who monitor Sentinel Trees across the state.

Our goal is to recruit volunteers who agree to “adopt” an individual tree, and report on the condition of the tree once or twice a year.

Changes in the condition of your Sentinel Tree could be important clues that lead to the detection of invasive forest pests and diseases. The greater the number of Sentinel Tree reports, the greater the chance of keeping these extremely damaging pests and diseases out of Michigan!
