In forests, trees shield each other from strong winds, at right.
However, when roads, driveways and homes are built on wooded sites, any trees that remain become susceptible to blow down because their root systems are often severely damaged during the construction process, below left.
Also, because their branches are often clustered near the top of the tree, they present a large “sail” that captures strong winds previously blocked by the trees that were removed. This often results in very tall trees dramatically snapping in half like toothpicks during severe storms!
