  • Invasive Blue Land Crabs Reported Along South Atlantic Coast: Coastal Georgia Residents Encouraged to Be Watchful

    • Dec 20, 2023
    • Georgia Department of Natural Resources.

    • Recent sightings of a large, non-native land crab along the South Atlantic coast, including in coastal Georgia, are a cause for concern, according to the Georgia Department of Natural Resources’ Wildlife Resources Division (WRD). Blue land crabs are native from Brazil to south Florida and can be as large as 5-6 inches. Sightings recently have been reported well north of the crabs’ native range, including the coasts of Georgia, South Carolina and North Carolina. Multiple reports have been made to Georgia WRD offices.

      The public is encouraged to take photos and report sightings of blue land crabs at Questions about blue land crabs? Contact a local Georgia WRD office (details at

  • Management Plan for the European Green Crab (Draft)

    • Jun 21, 2023
    • Aquatic Nuisance Species Task Force.

    • The National European Green Crab (EGC) Management and Control Plan was developed by a multi-agency European Green Crab Working Group for implementation by the Aquatic Nuisance Species Task Force following final approval.

      The purpose of the 2023 EGC plan is to provide guidance for efforts to prevent future introductions, to rapidly detect and respond to new invasions of EGC before they become established and create ecological and economic damage, and to manage current populations that pose an undue threat to resources of importance for ecosystems and local cultures. The 2023 EGC plan proposes to update the 2002 plan by providing a more focused set of approaches for future management, based on significant changes in the distribution of EGC, new technologies available for identifying sources and mechanisms of spread, better information regarding the tradeoffs for different management efforts, and new methods for data management and sharing. The 2023 EGC plan also describes current strategies for coordinating the activities of scientists, resource agencies, Tribal and First Nation organizations, and other entities.

      Public Comment Period -- Written comments must be submitted on or before February 9, 2024. For more information, see the Federal Register notice Draft Revised National European Green Crab Management and Control Plan (Dec 26, 2023)

  • USDA Forest Service Announces Nearly $19M to Fight Invasive Species Threatening Nation’s Forests -- $1M Going to Projects in Northern Research Station

    • Sep 7, 2023
    • USDA. FS. Northern Research Station.

    • USDA Forest Service is making a nearly $19 million strategic investment to address invasive species threatening forests across the country. Funding for over 60 projects was made possible by President Biden’s Bipartisan Infrastructure Law.

      These investments were awarded to public and private organizations, tribes, states, and local landowners and Forest Service research stations to respond to the spread of damaging invasive species, which includes wood boring insects, exotic fungi, non-native plant species, and other potential pests and pathogens. The funds will support activities focused on invasive species detection, prevention, eradication, and research.

  • USDA Protects Fruit, Vegetable and Livestock Producers with Emergency Funding to Address Exotic Fruit Fly and New World Screwworm Outbreaks

    • Dec 15, 2023
    • USDA. Animal and Plant Health Inspection Service.

    • USDA's Animal and Plant Health Inspection Service (APHIS) is using emergency funding to respond to the threats associated with growing outbreaks of exotic fruit flies and New World screwworm. U.S. Secretary of Agriculture Tom Vilsack approved the transfer of $213.3 million from the Commodity Credit Corporation to APHIS to directly support emergency response efforts domestically and internationally to protect fruit, vegetable and livestock industries and producers.

      "Increasing our response efforts to exotic fruit fly and New World screwworm outbreaks is critical to minimizing their potential impact on our nation’s agriculture and trade," said USDA Under Secretary for Marketing and Regulatory Programs Jenny Lester Moffitt. "This funding will enable us to swiftly prevent both populations’ further spread before they become established and harder to eradicate."

  • Study Identifies Florida’s Potential Invasive Species Threats

    • Dec 15, 2023
    • University of Florida. IFAS Extension.

    • In a first-of-its-kind study for North America, scientists accumulated a list of potential invasive species for Florida, and researchers deemed 40 pose the greatest threat. A team of experts, led by University of Florida scientists, evaluated terrestrial, aquatic and marine species with characteristics that make them particularly adept at invasion. Their list includes 460 vertebrates, invertebrates, algae and plants.

      The study, "Identifying invasive species threats, pathways, and impacts to improve biosecurity," was funded by the Florida Fish and Wildlife Conservation Commission and the UF/IFAS Dean for Research. It is published in the journal Ecosphere.

  • Lionfish Invitational

    • DOC. NOAA. Flower Garden Banks National Marine Sanctuary.

    • NOAA's Flower Garden Banks National Marine Sanctuary (FGBNMS) is partnering with Lionfish Invitational, and others to use trained divers to help conduct research and remove invasive lionfish within FGBMNS. This multi-day event is a science-based research expedition in which 11 dive teams work to remove as many lionfish as possible, while also recording helpful data on lionfish activity and sightings. In addition, a science team of 8 divers conducts surveys to determine what species, quantities and sizes of fish are present at each designated site before and after the removals. Applications are due Mar 1, 2024. The 2024 expeditions will take place on the following dates:

      • ​June 23-27, 2024
      • August 11-15, 2024

    • USDA. ARS. Tellus.

    • ARS works with foreign scientists to prevent overseas diseases from spreading to the United States. This collaboration specifically targets research that cannot be conducted in the U.S., either because a disease does not exist here or the expertise in a pathogen resides overseas. Of particular concern are emerging diseases that may spread from animals to infect humans.
