The principal objectives of Certified Ontario Tree Markers are:
(1) to develop and promote sound stewardship of Ontario’s forest resources where harvesting is carried out using partial-harvest systems;
(2) to take an active role in preventing forest degradation resulting from inappropriate harvesting through the use of partial-harvesting systems;
(3) to increase awareness and appreciation of the value of tree marking in partial-harvest systems; and
(4) to seek the highest standards in all tree marking activities in Ontario’s forests.
