  • Spotted Lanternfly Identified in Illinois

    • Sep 26, 2023
    • Illinois Department of Natural Resources.

    • The Illinois Department of Agriculture has confirmed the first detection of spotted lanternfly (Lycorma deliculata) in Illinois. Following a report of a live adult on Sept. 16, state, federal, and local officials coordinated a site visit near the area of the report and identified a moderately populated area of spotted lanternfly (SLF) on Sept. 18. Specimens were collected and submitted for identification, and confirmatory results were received on September 26. The spotted lanternfly does not present any human or animal health concerns.

      If you see SLF or suspect it, report it to A fact sheet, including photos, is available through the University of Illinois Extension [PDF, 1.6 MB].

  • First Michigan Detection of Invasive Hydrilla Triggers Response

    • Oct 2, 2023
    • Michigan Invasive Species Program.

    • Hydrilla, considered one of the world's most invasive aquatic plants, has been detected for the first time in Michigan. The Department of Environment, Great Lakes and Energy confirmed two small populations of the plant in adjacent private ponds on residential properties in Berrien Springs in Southwest Michigan.

      The small patches of hydrilla (Hydrilla verticillata) were discovered during routine monitoring following treatment for another invasive plant, parrot feather, which was found in the pond in 2020. Both species are prohibited in Michigan, meaning it is unlawful to sell, possess or import them into the state, and both are on Michigan’s invasive species watch list due to their potential environmental threat. Any suspicious aquatic plants should be reported as soon as possible to Include close-up photos and provide the location of the detection in your report. More information on identifying and reporting invasive aquatic plants can be found at

  • New to New Hampshire - Invasive Spiny Water Flea Confirmed in Lake Winnipesaukee

    • Sep 29, 2023
    • New Hampshire Department of Environmental Services.

    • This summer, state biologists from the New Hampshire Department of Environmental Services (NHDES) documented the presence of a new aquatic invasive species to New Hampshire. The spiny water flea (Bythotrephes longimanus) was documented on September 13 in the deepest location of Lake Winnipesaukee, in the Broads in Gilford, New Hampshire. Subsequent sampling also confirmed spiny water flea presence in Alton and Wolfeboro areas of the lake. State biologists believe this is a recent infestation.

    • Louisiana State University. AgCenter Research and Extension.

    • Louisiana is home to some of the most destructive invasive species found in the United States. The LSU AgCenter has long worked to monitor and manage these non-native insects, weeds and wildlife. To better understand and control invasive species, the LSU AgCenter is developing a Center of Research Excellence for the Study of Invasive Species. The Louisiana Board of Regents approved the creation of the center on Sept. 20.

  • Invasive Zebra Mussels Now Confirmed in North Carolina

    • Sep 22, 2023
    • North Carolina Wildlife Resources Commission.

    • The North Carolina Wildlife Resources Commission (NCWRC) announced today that zebra mussels, a harmful invasive aquatic species, have been identified in an Iredell County waterbody. This is the first time this species has been identified in the wild in North Carolina. On Thursday, September 21, 2023, NCWRC, with assistance from scuba divers from the U.S. Fish and Wildlife Service, investigated and confirmed a report of zebra mussels in a quarry on private property. NCWRC believes the mussels are contained to the quarry and is working on options for treatment while continuing its investigation.

      To report suspected zebra mussels, please contact the NCWRC's district fisheries biologist offices. Visit NCWRC's aquatic nuisance species webpage for guidance on disinfecting snorkel and SCUBA gear and for more information on zebra mussels.

  • Media Release: IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) Invasive Alien Species Assessment

    • Sep 4, 2023
    • Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).

    • A new scientific report, Summary for Policymakers of the Thematic Assessment Report on Invasive Alien Species and their Control of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, offers the most exhaustive look yet at how nonnative plants and animals can drive extinctions, disrupt food systems and harm human health. The report was compiled by 86 experts from 49 countries, who drew on thousands of scientific studies and contributions from Indigenous people and local communities. Key points:

      • Invasive Alien Species Pose Major Global Threats to Nature, Economies, Food Security and Human Health
      • Key Role in 60% of Global Plant & Animal Extinctions
      • Annual Costs Now >$423 Billion – Have Quadrupled Every Decade Since 1970
      • Report Provides Evidence, Tools & Options to Help Governments Achieve Ambitious New Global Goal on Invasive Alien Species

  • Invasive New Zealand Mudsnails Discovered in Lake Tahoe

    • Sep 21, 2023
    • Tahoe Regional Planning Agency.

    • Divers monitoring Lake Tahoe have discovered invasive New Zealand mudsnails in areas off the South Shore, the Tahoe Regional Planning Agency (TRPA) and Tahoe Resource Conservation District (Tahoe RCD) announced today. This is the first time the species has been detected in the Tahoe Basin.

      Following rapid response protocols under the federally approved Lake Tahoe Aquatic Invasive Species Management Plan, TRPA convened an incident team comprised of staff from TRPA and Tahoe RCD and partner experts. The team is rapidly deploying scientists, beginning with lake-wide dive surveys to determine the extent of the infestation and sharing all available information with state and federal wildlife managers through the Lake Tahoe Aquatic Invasive Species Coordinating Committee. Get up-to-date information on the response and potential protocols for management of the infestation on the TRPA New Zealand mudsnail page.

    • Noxious weeds plague farmers and ranchers, push out native species, and cause both economic and ecological damage. Synthetic herbicides are often used to control the spread of these plants, however, some species have developed a resistance to these chemicals.
