In arboriculture, what does “mitigation” primarily refer to?

Mitigation in arboriculture primarily refers to reducing potential harm from trees. This concept encompasses various practices aimed at addressing risks associated with trees, such as structural weaknesses, diseases, pests, or their placement near structures and people. By identifying risks and implementing strategies to manage them, arborists can prevent damage or injury caused by tree failure, overgrowth, or improper placement.

For instance, mitigation might involve pruning to remove hazardous branches, cabling to support weak limbs, or employing root barriers to prevent damage to sidewalks or foundations. Ultimately, the goal is to enhance safety and health in the environment where the trees are situated, ensuring that the trees can coexist with their surroundings without causing harm.

The other options touch on aspects of tree care but do not encapsulate the fundamental goal of mitigation in the context of arboriculture, which is focused on risk reduction and safety.
