The loss of nearby trees often provides a warning regarding the health and structural integrity of trees that remain standing.
This is particularly true where relatively recent construction activity such as the building of a new home or other significant excavation work has occurred. Keep in mind that the excavation work does not need to have been to great depth as almost the entire root system of even very, very large trees is within a foot of the soil surface!
In the photograph at the top of the page, for example, the roots of the trees near the one that blew down and crushed the parked car during a severe thunderstorm (fortunately, no one was in the care) have also been damaged during past sidewalk, driveway and street repairs.
Therefore, they may also be at risk for catastrophic failure and should be inspected frequently.
