New state regulations to help prevent the spread of quagga mussels and zebra mussels went into effect in Mar 2010. These regulatory measures, known as "Director's Orders," were authorized by the Aquatic Invasive Species Interdiction Act passed by the Arizona Legislature in 2009. The orders contain a list of aquatic invasive species for Arizona, a list of waters where aquatic invasive species are present, and mandatory conditions for the movement of watercraft.

The emerald ash borer is a half-inch long metallic green beetle with the scientific name Agrilus planipennis Fairmaire. Larvae of this beetle feed under the bark of ash trees. Their feeding eventually girdles and kills branches and entire trees. Emerald ash borer was first identified in North America in southeastern Michigan in 2002.
