Saturated Soils With Strong Winds is a 1-2 Punch For Trees

Trees are dynamic structures which grow with the ability to flex and bend even under great force. That’s why, through the ages and in most cultures, large trees have been a sign of strength and longevity.

However, despite most trees having a solid and secure root system, any tree’s root system is susceptible to weakening by excessive rainfall and root slippage. The water-holding capacity of soil has its limits. When soil structure loosens, it releases its grip or adhesion between the root structure and soil particles. Excessive rainfall loosens soil and predisposes a tree to uproot.

Depending on the species of the tree and the size of the leaf canopy, it can act as a sail, catching the gusts of wind. The taller the tree the more susceptible they are to wind-through. Tree height adds leverage which increases the pressure on the root system.

Trees can also have other compromised root system issues, such as root rot, cavities, girdling roots, and co-dominant trunks with split root systems. Tree failure is usually a combination of pre-existing conditions and environmental influences. As arborists, we try to mitigate what we can through observation, diagnosis, pruning, and at times preemptive removal.
