When do pine tree roots cause subsidence?

Pine tree roots can cause subsidence when they grow in areas with moist or loose soil, as they absorb significant amounts of water, leading to soil shrinkage and destabilization. Additionally, their expansive root systems can disrupt the soil structure, resulting in uneven settling. This is particularly problematic in urban environments where soil compaction and drainage are already compromised. The combination of water extraction and soil disturbance can ultimately lead to localized subsidence around the tree.
