D. Burke Burke’s Backyard 🌐 ‘Widow Maker’ During a bushfire, some trees burn and fall over, but others don’t fall for hours or days later. Sometimes the trees are structurally weakened, like the hollow one shown in our segment. Other times the trees dry out and lose water pressure in the trunk or branches, and so they lose their strength. On a still, silent day, long after the fire has passed through, a huge branch or the whole tree can suddenly drop. These trees are so dangerous Don refers to them as ‘widow makers.’.
