Some research and a conversation with a Calif. State Parks Ranger disclosed that California, and several other states are instituting "Buy it where you burn it" policies to discourage people from transporting firewood, because firewood is known to harbor disease-causing pests that may not exist in the area. Just like the invasive species bans and controls on boats that are intended to control the Quagga Mussel and similar water-borne pests, the aim of the firewood ban is to prevent the spread of such pests as the Emerald Ash Borer, Asian Longhorned Beetle, and others.
