  • San Diego Area Agencies Responding to Discovery of Invasive Seaweed in San Diego Bay

    • Nov 16, 2023
    • Port of San Diego (California).

    • The Port of San Diego, along with the Southern California Caulerpa Action Team (SCCAT), the City of Coronado, and the Coronado Cays Homeowners Association (CCHOA), are responding to the discovery of an invasive seaweed scientifically known as Caulerpa prolifera in the Coronado Cays area of San Diego Bay.

      In late September, divers found a small patch of Caulerpa prolifera while conducting an in-water pre-construction eelgrass/Caulerpa dive survey as a permit condition for a dock replacement project. Additional patches were discovered nearby during follow-up surveys. The total find within the Cays is about one-quarter of an acre. The SCCAT has prepared a Rapid Response Eradication Plan to address the immediate need to eradicate this invasive species.

  • Army Corps of Engineers: Better Data and Planning Needed to Combat Aquatic Invasive Species

    • Nov 6, 2023
    • United States Government Accountability Office.

    • Quagga and zebra mussels have spread rapidly across the country since they were first discovered in the late 1980s and, according to U.S. Army Corps of Engineers officials, have spread to every major river basin in the U.S. except the Columbia River Basin in the northwest. The mussels typically are spread by recreational watercraft such as boats, canoes, and Jet Skis that have been in infested waters. Once established in a water body, the mussel species are extremely difficult to eradicate because they have no natural predators in the U.S. and rapidly reproduce.

      GAO was asked to examine efforts the Corps has undertaken to prevent the spread of aquatic invasive species into the Columbia River Basin by recreational watercrafts. This report [PDF, 3.24 MB] provides information on the Corps' Watercraft Inspection and Decontamination Program and its role in helping to prevent the introduction or spread of quagga and zebra mussels—the aquatic invasive species of greatest concern to the Corps—as well as program challenges and opportunities for improvement.

    • California Department of Agriculture.

    • A portion of Los Angeles County has been placed under quarantine for the Mediterranean fruit fly following the detection of two wild flies in the Leimert Park neighborhood in the City of Los Angeles. The USDA, the Los Angeles County Agricultural Commissioner, and California Department of Agriculture are working collaboratively on this project.

      Under International Plant Protection Convention (IPPC) standards, Ceratitis capitata  is a transient pest under eradication that is present only in one area in California.  This species is not widely distributed and is under official control in the U.S.

  • An Exotic Tick That Can Kill Cattle is Spreading Across Ohio

    • Nov 3, 2023
    • The Ohio State University.

    • A species of exotic tick arrived in Ohio in 2021 in such huge numbers that their feeding frenzy on a southeastern farm left three cattle dead of what researchers believe was severe blood loss. The scientists from The Ohio State University have reported in the Journal of Medical Entomology on the state’s first known established population of Asian longhorned ticks, and are now conducting research focused on monitoring and managing these pests.

      Ohioans are encouraged to help with research efforts: People who think they’ve spotted an Asian longhorned tick can email for instructions on how to collect the specimen and send it to Ohio State scientists as part of ongoing surveillance. To date, the lab has received Asian longhorned ticks from residents of 11 Ohio counties. More information about spotting Asian longhorned ticks and preventing tick exposure is available on Ohio State’s Bite Site hosted by the College of Food, Agricultural, and Environmental Sciences Knowledge Exchange.

  • Biocontrol Against a Thirsty Invasive Grass in Arid Regions of the U.S.

    • Oct 30, 2023
    • USDA. ARS. Tellus.

    • Giant reed, Arundo donax, is a large, fast-growing invasive grass that has invaded at least 100,000 acres of "riparian" habitat in the southwestern and southeastern U.S. and is present as far north as Ohio and Washington State. Watch this video to learn how ARS researchers are using biocontrol (insects) to reduce the presence of this invasive plant.
