Many visitors to Arizona live in areas under quarantine for pests such as: emerald ash borer, gypsy moth, insects and diseases affecting pecan trees, or the imported fire ant- and it is illegal to move any regulated items (most firewood is considered a regulated item) from quarantined zones out of those states and into Arizona. Pecan firewood is prohibited from entering the state without proper treatment and certification. Eighteen states in the Central and Eastern US prohibit bringing hardwood firewood originating from Arizona into their state, to prevent the movement of thousand cankers disease. Regionally important pests such as the polyphagous shot hole borer and the soapberry borer pose a threat to Southwestern native forests, and these pests can be moved on firewood. Goldspotted Oak Borer while native to southeastern Arizona forests, has been responsible for major oak mortality in southern California Oak trees and was most likely introduced through the movement of firewood- underscoring the importance of using local firewood. This summary is accurate to the best of DMF staff abilities as of 25 September 2019.
