Construction damage to trees can lead to a variety of negative consequences that compromise their health and viability. Trunk damage can impair the tree’s ability to transport nutrients and water, as well as its structural integrity. Root damage is particularly detrimental since roots are essential for stability and nutrient absorption; injuries to the root system can lead to dieback and decline. Soil compaction, a common issue during construction, reduces the pore space in the soil, limiting air and water flow to the roots, which can stifle growth. Branch tearing can occur from careless equipment handling or excessive weight, leading to wounds that invite pathogens. Collectively, these factors significantly impact the tree's overall health, longevity, and function within the ecosystem.

In contrast, improved growth rates, increased resistance to pests, and enhanced carbon sequestration are typically the beneficial outcomes of proper tree care and maintenance, rather than the result of damage caused by construction activities.
