Home Grown: Big Trees Felled By Tiny Fungi.

Urban trees tend to have shortened lives, some living no more than 50 to 80 years. Urban forests in many metro areas have started to mature and decline, and are very susceptible to trunk-rotting and buttress root-rotting organisms.

Wood-rotting organisms can slowly nibble away at trunks and buttress roots. Trees often regenerate new, nonstructurally supportive feeder roots that mask the signs of structural root loss. Many trees that topple look perfectly healthy before they fall. Afterward, it becomes clear that there were absolutely no structural roots remaining for support.

The best time to scout for symptoms of a fungal infection is just after a long period of cool, wet weather.
