Mechanical injuries to trees often result in stress and decline. When a tree experiences physical damage, whether from equipment, storms, or human activities, it can lead to a variety of negative effects. These injuries disrupt the tree's protective barriers, making it more vulnerable to pests, diseases, and environmental stressors. The energy that the tree would typically allocate for growth, fruit production, and overall health can shift toward healing the injury, which can result in reduced vigor and general decline.

The other outcomes listed do not typically occur following mechanical injuries. While it might seem that some mechanical interaction could enhance aspects of tree health or appearance, research consistently points to the adverse effects primarily associated with damage. Thus, understanding the implications of mechanical injuries underscores the importance of proper tree care and protection measures.
