Certified Arborist Practice Exam

This type of cut is used to remove limbs back to laterals that are large enough to sustain the remaining branch and assume the terminal role:

1. Plant growth regulators (anti-gibberillins)

2. Thimble

3. True/False: You can install J-hooks in decay

4. Reduction

The correct answer is: True/False: You can install J-hooks in decay

The correct choice for the question pertains to a pruning technique designed to maintain the health and structure of a tree while managing its size. This type of cut involves removing limbs back to lateral branches that are capable of sustaining the remaining branch and taking on the role of the terminal leader. The term that describes this technique most accurately is "Reduction." Reduction cuts aim to selectively remove portions of the tree in a way that minimizes stress and encourages healthy regrowth. This practice not only aids in maintaining the desired shape and size of the tree but also ensures that the remaining branches can thrive due to their appropriate size and health. The other options do not relate to the pruning technique in question. Specifically, plant growth regulators are chemicals used to influence growth patterns but do not involve the physical act of pruning. J-hooks pertain to rigging methods used in arboriculture, particularly in gear installation; they are not a type of cut. A thimble, while a useful tool in rigging, does not relate to the pruning context or the specific cut described. Therefore, the choice that accurately reflects the type of cut used for limb reduction is "Reduction."
