The majority of a tree's root system is typically anchored to the first 6-12 inches of the soil. It's also the part of the ground that bears the brunt of over-saturation in flood situations. When the soil loosens around the roots, it can lead to the uprooting of a tree. This is a problem we saw a lot of in the aftermath of Irene.
