Arizona Game and Fish Department.
In 2009, the Arizona Legislature passed the Aquatic Invasive Species Interdiction Act, which authorized the regulatory measures known as "Director's Orders". 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. A map of affected waters (PDF | 1.1 MB) is also available.
Arizona Plant Diagnostic Network Pest Alerts
University of Arizona. Cooperative Extension.
This list of the most serious biotic pests and pathogens is maintained by the State (Arizona Department of Agriculture) and Federal (USDA) regulatory agents. Their goal is to prevent the introduction and/or spread of these pests/pathogens in our state. The University of Arizona diagnosticians and Extension agents and State/Federal regulatory agents rely on the community to report any suspicious pests or pathogens found on the regulatory alerts.
Lake Powell Mussel Update
DOI. NPS. Glen Canyon National Recreation
Quagga mussel larvae, or veligers, were first confirmed in Lake Powell in late 2012 after routine water monitoring tests discovered mussel DNA in water samples taken from the vicinity of Antelope Point and the Glen Canyon Dam. Adult mussels were first reported in March 2013 when a local marine services business discovered 4 adult mussels on a boat that had been pulled for service. Continued mussel education and prevention activities will minimize the chances that mussels will colonize other areas of the lake.
