The large tree snapped and injured an Oregon woman who was dining on the restaurant’s narrow outdoor patio. The old tree on the edge of the scenic 14-acre Big Woods preserve reportedly was weakened by disease. But several factors can make trees susceptible to snapping at any time or toppling over in high winds.
