  • 2022 Lionfish Invitional

    • 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 (June 26-29, 2022) 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 were due by April 10, 2022.

  • NYDEC and Canal Corporation Announce Comprehensive Effort to Protect New York's Waters from Aquatic Invasive Species Round Goby

    • Mar 24, 2022
    • New York State Department of Environmental Conservation.

    • The New York State Department of Environmental Conservation (DEC) and the New York State Canal Corporation today announced a new comprehensive effort, including a new rapid response plan, to combat the potential spread of the round goby, an aquatic invasive species, to the Lake Champlain Basin following the discovery of the fish in the Hudson River near Troy in July 2021. The round goby is one of the biggest threats to New York waters, particularly Lake Champlain, and DEC lists round goby as a prohibited invasive species in the New York Code of Rules and Regulations. Native to Europe and Asia, this fish was introduced in the Great Lakes in 1990, and spread throughout the lakes' system. Round goby reproduces quickly, outcompetes native benthic fish species for food and habitat, eats the young and eggs of other fish, and can transport botulism up the food chain to waterfowl. Working with partners, the agencies will develop a rapid response plan to take effect before the opening of the Canal system on May 20 to identify appropriate actions if round goby enter the Champlain Canal.

  • Smokies Nonprofit Invites Public to Participate in Smokies Most Wanted

    • Feb 26, 2022
    • Discover Life in America.

    • Discover Life in America, the nonprofit research partner of Great Smoky Mountains National Park, is inviting the public to participate in its latest project, Smokies Most Wanted, an initiative that allows visitors to help conserve park species by recording sightings of animals, plants and other organisms from their smartphones. Powered by the nature app iNaturalist, Smokies Most Wanted encourages park visitors to document any organism they encounter while hiking, camping, or otherwise enjoying the park — from birds to wildflowers, insects to lichens. DLiA then uses the data collected through iNaturalist for a variety of functions, like recording new park species or detecting invasive ones, learning about under-studied or rare species, and mapping species across the park.

  • Joro Spiders Likely to Spread Beyond Georgia

    • Mar 3, 2022
    • University of Georgia. UGA Today.

    • The Joro spider, native from Japan, first arrived stateside around 2013 and has since spread across the state and Southeast. But new research from the University of Georgia suggests the invasive arachnids could spread through most of the Eastern Seaboard of the U.S. Joros don't appear to have much of an effect on local food webs or ecosystems, said Andy Davis, corresponding author of the study and a research scientist in the Odum School of Ecology. They may even serve as an additional food source for native predators like birds.

  • Help Stop the Spread of Aquatic Invasive Species in Wyoming

    • Mar 7, 2022
    • Wyoming Game & Fish Department.

    • The Wyoming Game and Fish Department is offering training for members of the public to become a certified Wyoming aquatic invasive species inspector. The free, day-long sessions are offered throughout the spring in statewide locations and are open to anyone interested in preventing the spread of AIS through watercraft inspection. The training includes information on basic biology of invasive species, the impacts of AIS, transport vectors and distribution of AIS. It includes classroom instruction, a question-and-answer session and a hands-on watercraft inspection exercise. Those who complete the class will be certified to inspect watercraft.

  • USDA Confirms Citrus Canker in a South Carolina Nursery and Takes Action to Collect and Destroy Affected Plants

    • Mar 9, 2022
    • USDA. Animal and Plant Health Inspection Service.

    • The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of citrus canker disease in a nursery in South Carolina. The nursery sells plants to consumers through online sales. Citrus canker causes citrus leaves and fruit to drop prematurely, and results in lesions on citrus leaves, stems and fruit. Fruit infected with the bacterium that causes citrus canker (Xanthomonas axonopodis) is safe to eat, but it may not be marketable because of the lesions. Citrus canker is not harmful to people or animals.

      Together with state partners, APHIS is working to collect and destroy the plants shipped to consumers in 11 states and trace plants that were sold to determine additional locations of potentially infected plants. The states include Alabama, California, Florida, Georgia, Louisiana, Mississippi, Nevada, Oregon, South Carolina, Texas, and Washington. If you live in one of the 11 states and bought citrus plants online that came from South Carolina between August 5, 2021, and February 17, 2022, please keep your plants for now. If you purchased a plant or plants that might be infected, APHIS and/or state officials will contact you in the next several days to collect and properly dispose of any plants purchased from the nursery. You can also call your local USDA office.

  • New Research Verifies Invasive Tegu Lizards Adaptable to Various Climates

    • Mar 9, 2022
    • DOI. United States Geological Survey.

    • Invasive tegu lizards from South America are currently established in four locations in Florida and negatively impact native, ground-nesting animals in the Greater Everglades Ecosystem. Two newly published research studies from the U.S. Geological Survey show that, depending on their size and body condition, tegu lizards could survive in cooler, northern climates.

      The Argentine black and white tegu is a large lizard from South America currently inhabiting the Florida counties of Charlotte, Hillsborough, Miami Dade and St. Lucie. Tegus are introduced to the U.S. through the pet trade and then likely released from captivity into the environment. "Several lines of evidence from recent USGS research studies published from 2018 to 2021 now provide clear indication for managers that the entire southeast portion of the United States is at risk of tegu establishment if lizard releases continue unabated," said Amy Yackel Adams, a USGS research ecologist.

  • Biological Invasion Costs Reveal Insufficient Proactive Management Worldwide

    • May 2022; available online Feb 2022
    • Science of the Total Environment 819 (2022) 153404

    • The global increase in biological invasions is placing growing pressure on the management of ecological and economic systems. However, the effectiveness of current management expenditure is difficult to assess due to a lack of standardised measurement across spatial, taxonomic and temporal scales.

      Research Highlights:

      • Since 1960, management for biological invasions totalled at least $95.3 billion.
      • Damage costs from invasions were substantially higher ($1130.6 billion).
      • Pre-invasion management spending is 25-times lower than post-invasion.
      • Management and damage costs are increasing rapidly over time.
      • Proactive management substantially reduces future costs at the trillion-$ scale.

  • New Cogongrass Campaign Addresses Threat to Alabama

    • Mar 2, 2022
    • Alabama Department of Agriculture and Industries.

    • The Alabama Department of Agriculture and Industries (ADAI) has initiated a new social media campaign to raise awareness of the dangers cogongrass poses to the state. With agriculture and natural ecosystems at risk, ADAI is calling on Alabamians to recognize this threat and share the information.

      Cogongrass has now infested more than 75 percent of Alabama's counties. This federally regulated noxious weed was introduced in the U.S. in 1911 as packing material in the port of Mobile. In the decades since, it has greatly expanded and become more dangerous. Visit to learn how to spot cogongrass and report it when it blooms again in the spring.
