Soil compaction significantly impacts tree stability primarily by reducing root growth and making trees more susceptible to falls. When soil is compacted, it decreases the pore spaces between soil particles, which restricts the movement of air, water, and nutrients that are essential for healthy root development. Roots require a certain level of oxygen and space to grow effectively; compacted soil creates a challenging environment for roots to expand.

As roots struggle to penetrate and establish themselves in compacted soil, they may develop shallower and weaker root systems. This lack of robust root anchorage means that trees can become less stable and more prone to toppling during high winds or heavy storms. It can also lead to increased stress on the tree, making it more vulnerable to diseases and pests, further compromising its structural integrity. Thus, understanding the relationship between soil compaction and tree stability is crucial for proper tree management and maintaining healthy urban and rural landscapes.
