About Tree Markers
Tree markers help ensure the sustainability of Ontario's public and private woodlands by making ‘cut and leave' decisions for individual trees. The trees are evaluated based on their:
- growth, health and product potential
- ability to provide seed
- wildlife benefits
The management objectives for particular woodlands are also considered.
