  • How is the EPA Involved in Addressing Aquatic Nuisance Species?

    • Environmental Protection Agency.

    • In addition to intergovernmental efforts and research to detect and monitor aquatic nuisance species (ANS), the EPA addresses ANS using numerous regulatory tools.

      The EPA's National Pollutant Discharge Elimination System (NPDES) Vessel General Permit (VGP) and Small Vessel General Permit (sVGP) regulate discharges incidental to the normal operation of commercial vessels, including ballast water and hull fouling, which are both pathways for introductions of aquatic nuisance species. The EPA and the Department of Defense are jointly developing the Uniform National Discharge Standards for vessels of the Armed Forces which will also regulate ballast water and hull fouling to help control the introduction of aquatic nuisance species.

      Note: On December 4, 2018, President Trump signed into law the Frank LoBiondo Coast Guard Authorization Act of 2018, which includes as Title IX the

To report suspicious pest species arriving on plants or articles from foreign countries or other states, please contact the MDA's Report a Pest. To report invasive aquatic plants or wild animals, please contact the DNR Invasive Species Program at: 651-259-5100 (metro) or 1-888-646-6367.

  • How to Save the Florida Citrus Industry?

    • Apr 24, 2023
    • USDA. ARS. Tellus.

    • Imagine a devastating plant disease that sweeps the land, decimating crops. For Florida’s citrus growers, that apocalyptic vision is not a horror movie, but a reality: since it was first identified in the Sunshine State in 2005, citrus greening disease has reduced Florida’s citrus production by a whopping 70%. Without any treatment or cure available, desperate growers have cut down infected trees or abandoned their groves entirely. Scientists have been racing to come up with a solution. Now, an ARS research team believes it may have one, in the form of: stingrays.

  • How USDA Scientists are Winning the Battle Against Invasive Fruit Flies

    • Apr 27, 2023
    • USDA. Blog.

    • Invasive fruit flies, such as the Oriental, Mexican, Mediterranean, and European cherry fruit fly, pose threats to many U.S. commercial and homegrown crops. If established, these flies could cause significant economic losses, requiring costly treatments to protect fruits and vegetables and reducing the marketability of infested fruit both locally and abroad. What’s at stake? The market value of invasive fruit fly-host commodities totaled approximately $11.7 billion in the United States in 2022. Approximately $8.3 billion of that was from California and $2.9 billion from Florida.

  • ICYMI Bulletin: USGS Uses "eDNA" to Combat Invasive Species

    • Oct 16, 2020

    • Invasive zebra and quagga mussels are an immediate threat to Western states. With no controls, they spread rapidly, foul boats and equipment, clog water intake, and increase costs to hydropower operations and municipal water utilities. Even dead mussels can be a nuisance, littering beaches with shells. Management of these invaders is expensive; in the Great Lakes, managing mussels costs about $500 million annually. Until 2007, the mussels were limited to waterways and lakes east of the Mississippi, but now they have spread westward. In 2016, quagga mussels were found in Lake Powell.

      Unfortunately, there are no foolproof existing technologies or treatments to eradicate established mussel populations in large, open water systems in an environmentally sound manner. Early warning, however, helps us prepare before the mussels or other invasive species arrive.
