Ontario Tree Marker Program

Ontario Tree Marker Website






The Tree Marker Training Program teaches the wise use of silvicultural systems used to sustain and enhance forest ecosystems that existing and future forest industry depends on.

The trees or stands that are to be cut or left in harvesting or any other silvicultural operation can be designated orally, physically through tree marking, or some combination of the two. However, tree marking is the preferred mechanism to regulate the management systems that involve partial cutting.  That is, those operations in which a residual stand remains for some time after treatment.  Quality control is obtained by marking the trees that are to be removed or those to be left.  The logging operators are responsible only for removing the designated trees with due care for the site and vegetation to be left.  The tree marker bears a high proportion of the responsibility for the planning of the logging and the future stand's health, vigour and ability to meet the needs of other forest values.  For these reasons, tree markers need to be highly trained in all aspects of forest ecological and silvicultural systems management.
