Tree marking is the careful selection of individual trees for retention or harvest based on their growth, health, product potential, ability to provide seed and wildlife benefits.
How it works
Tree markers follow a silvicultural prescription, or plan, approved by a Registered Professional Forester. Certified tree markers attend an intensive one-week course that includes written and practical testing. In addition to passing the course, they must mark in an operational setting and have a successful audit.
Marked trees will have a band marked around the tree trunk, as well as a single slash of paint at the base. The slash of paint at the base remains on the stump even after the tree is removed, indicating to auditors that the tree was marked.
Tree markers identify trees to be both retained and removed based on spacing, tree quality, and health and regeneration objectives. Trees are also marked to retain if they represent wildlife features or areas of concern. Please see below for some examples of these features.
To learn more about tree marking, please look at the Ontario Tree Marking Manual or visit the Ontario Tree Marking Program website.
Special Habitat Features that are Retained
Cavity Trees:
Living trees with existing or potential to develop roost, nest, escape or feeding cavities
Mast Trees:
Species that produce edible fruits for wildlife (i.e. Oak, Beech, Cheery, etc)
Supercanopy Tree
Large, living trees that emerge above the main canopy of a stand (i.e. White Pine emerging from hardwood canopy)
Stick Nests
Large birds often use the same nest repeatedly, therefore is it very important we conserve these valuable habitat features.
Moose Summer Habitat
To avoid heat stress in summer months, moose bed in stands of lowland conifers or hardwoods. Aquatic feeding areas are also protected.
Winter Cover for Deer and Moose
Dense conifer cover helps deer and moose conserve energy in the winter by reducing snow depths and providing thermal cover.
