True/False: Trees that lean due to ground failure or root injury have a high potential to fail:

False
Root collar excavation
Reacton wood
Mitigation

The correct answer is: False

The statement regarding trees that lean due to ground failure or root injury having a high potential to fail is true, which means the answer is not aligned with the correct understanding of tree stability. Trees that exhibit leaning, particularly as a result of compromised roots or ground conditions, indicate instability and a greater risk of failure. The root system plays a crucial role in anchoring the tree; if the roots are injured or the supporting soil fails, the structural integrity is compromised. Trees that lean often do so because they cannot support their weight evenly, which could lead to a catastrophic failure, especially under stress from wind or heavy loads. The orientation of growth may also shift in reaction to these stressors, making it harder for the tree to redistribute weight properly. Therefore, recognizing the potential for failure is vital in arboriculture for assessing risks and making management decisions regarding leaning trees.
