Many factors can affect the health of Yukon's trees. Through our forest health program, we monitor and report on concerns to Yukon's forests.
Help us monitor forest health
If you have concerns about a tree, you can contact the Forest Management Branch to:
- help identify the cause;
- learn about the possible impact to the tree’s health; and
- help us monitor forest pests and disease.
Phone 867-456-3999 or email forestry@yukon.ca.
