  • 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.

  • The Trouble with Noxious Weeds: Predicting Herbicide Resistance

    • Sep 2023
    • USDA. FS. Rocky Mountain Research Station. Science You Can Use Bulletin.

    • 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.

  • First Occurrence of Mile-a-Minute Weed Confirmed in Maine, Urgent Action Required

    • Aug 8, 2023
    • Maine Department of Agriculture, Conservation & Forestry.

    • The Maine Department of Agriculture Conservation and Forestry (DACF) has recently verified the first known occurrence of mile-a-minute weed (Persicaria perfoliata) in Maine. This fast-growing invasive vine, native to India, Asia, and the Philippine Islands, poses a significant threat to nurseries, Christmas tree farms, reforestation projects, and restoration areas, as it can smother young plants and trees under its dense growth.

      Invasive species like mile-a-minute weed have the potential to cause severe harm to Maine's environment and economy. As part of our commitment to controlling and eradicating this invasive plant, the DACF urges the public to report any potential sightings promptly. If you encounter a vine resembling mile-a-minute weed, please visit the Maine Natural Areas webpage for identification information. If the plant matches the description, we encourage you to take photos, note the location, and report the finding via email to or call (207) 287-7545.

  • Burning Better

    • Sep 19, 2023
    • USDA. ARS. Tellus.

    • A new workshop unites practice with research on the beneficial effects of fire. As wildfires and toxic smoke pour across North America, millions of people are experiencing the harm that fire can cause. But fire can also be an ally in protecting natural landscapes when it is deployed in the right ways. That’s why ARS researchers recently led a workshop designed to meld the insights of science with the day-to-day operations of fire management, for professionals who use the practice known as prescribed burning (cultural control).

  • Invasive Red Fire Ants Found in Europe for the First Time

    • Sep 11, 2023
    • Natural History Museum (United Kingdom).

    • An invasive species of ant has been discovered in Europe for the first time. Nearly 90 nests of the red imported fire ant, or Solenopsis invicta, were found near the city of Syracuse, Italy, according to a new report published in the journal Current Biology. While the ants have occasionally been found in imported products in Europe, this is the first time they have become established in the wild.

  • National Public Lands Day

    • National Environmental Education Foundation (NEEF).

    • The 30th annual National Public Lands Day (NPLD) is on September 23, 2023! National Public Lands Day was established in 1994 and held annually on the fourth Saturday in September. This designated day is traditionally the nation's largest single-day volunteer effort and is focused on resilience and restoration. Volunteers can plant trees and native vegetation, build and refurbish trails, remove trash and invasive plants, repair bridges, restore historic structures, monitor endangered species, and restore habitats. Volunteer and find a NPLD event near you. See also:

  • How Does Climate Change Affect the Challenge of Invasive Species?

    • DOI. United States Geological Survey.

    • Changing climate conditions have bearing on every aspect of biological invasions, in some cases worsening existing problems. Climate change is creating new pathways for invasive species to be introduced, such as shipping routes that open up as sea ice retreats. Warmer temperatures can allow existing invasive species to expand their range into habitat that is currently too cool. Similarly, impacts to native species and people may change if new conditions affect invasive species abundance. Climate change may make existing invasive species control tools less effective, such as aquatic barriers that require minimum water flows.
