Certified Arborist Practice Exam

Mature trees are not generally tolerant of severe pruning. While they can handle some level of pruning, excessive removal of foliage and branches can negatively impact their health and structure. Severe pruning can reduce the tree's ability to photosynthesize effectively, leading to stress and potential decline. Additionally, it can create large wounds that invite pests and diseases, which can further compromise the tree's integrity. Therefore, the statement that mature trees are tolerant of severe pruning is false; they require careful management to ensure their longevity and health.
