COMMERCIAL LOGGING FOR WILDFIRE PREVENTION
... consider fuels greater than three inches (3) in diameter because it is mainly the fine-sized surface fuels that allows fire spread. Commercial logging operations remove large-diameter fuels which are naturally fire resistant, and leave behind an increased amount of fire-prone small-diameter fuels. ...
