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.

Invasive insect and arthropod species make for a lot of scary headlines—think emerald ash borer, spotted lanternfly, and Asian longhorned tick, just to name a few. But success stories in invasive-species response are out there. They just need to be told. One of those success stories is the eradication of the European grapevine moth (Lobesia botrana) in northern California after it was found there in 2009. A cooperative, multipronged response effort kept infestations from running wild, and it was declared eradicated in 2016, two years after the last adult moth was caught in the region. The story of this effort is recounted, along with analysis of the invasion’s dynamics, in a study published in January in the Annals of the Entomological Society of America.

The Iowa Department of Agriculture and Land Stewardship asks Iowans to be on the lookout for spotted lanternfly insects. The colorful but invasive and destructive insect is native to China, India, and Vietnam, and was accidentally introduced into Pennsylvania in 2014. It has since been confirmed in eleven states and often spreads by the movement of infested material or items containing spotted lanternfly egg masses. If allowed to spread further in the United States, this pest could seriously impact the country’s grape, orchard, nursery, and logging industries.

A community member notified the Iowa Department of Agriculture and Land Stewardship of the presence of two immature spotted lanternflies in Dallas County earlier this month. Federal identification confirmed the sample as a spotted lanternfly. Surveys of the immediate area have not resulted in signs of an ongoing infestation and entomologists hope the insects recently hitchhiked into the area.

If you think you have found a spotted lanternfly, please call the Entomology and Plant Science Bureau at 515-725-1470 or e-mail Entomology@IowaAgriculture.gov. You may also contact your local county Iowa State University Extension Office.

This year’s unusually warm winter and spring has led to the early hatch of spotted lanternfly (SLF) in states to our south.  Reports have come in over the past couple of weeks of SLF hatching from Virginia to Pennsylvania, and we anticipate them following suit here in Massachusetts in the next month.

Led by IUCN, a manual to support EU Member States and other stakeholders with incorporating animal welfare into their management of invasive alien species (IAS) of Union concern has been published. The publication, "Manual for the management of vertebrate invasive alien species of Union concern, incorporating animal welfare [PDF, 5.7 MB]", presents all measures that are available to eradicate and control the 22 vertebrate IAS included in the EU Regulation on IAS (listed as of December 2021). For each measure, information on their costs, effectiveness, side effects, and crucially, on their impacts upon animal welfare is provided, alongside case studies on their application.

IUCN has launched a global standard for classifying the severity and type of impacts caused by alien species, known as the Environmental Impact Classification for Alien Taxa (EICAT). This tool will alert scientists, conservation practitioners and policy makers to the potential consequences of invasive alien species, guiding the development of prevention and mitigation measures.

Washington State Department of Agriculture (WSDA) detected two Japanese beetles near Grandview and one near Sunnyside in 2021. Additionally, a resident reported numerous Japanese beetles devouring her roses in Grandview that summer.

Japanese beetles would pose a serious threat to farms, gardens, and the environment if they were to become established in Washington State. Please report any suspected sightings of Japanese beetle at PestProgram@agr.wa.gov or 1-800-443-6684. See WSDA's Interactive Japanese Beetle Response Map.

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.

We need your help to monitor for and report northern giant hornet sightings. By participating in a northern giant hornet citizen scientist project, you are helping protect your community from northern giant hornets.

Since the first report of a northern giant hornet in Washington in 2019 (known as the Asian giant hornet or the “murder hornet” back then), the Washington State Department of Agriculture’s (WSDA) Pest Program has been working to eradicate northern giant hornets. The best time to participate is from July through November. You are most likely to see or catch a northern giant hornet during this timeframe because colonies are established, and workers are out hunting.

Laurel wilt disease has been spreading through the U.S. since 2002 and is fatal to tree species in the laurel family. Forest Service researchers are continuing to monitor the disease, search for treatment methods, and develop a better understanding of how it is affecting sassafras and other susceptible species.

The Laurel Wilt Public Dashboard story map – a collaboration between the Georgia Forestry Commission, multiple branches of the Forest Service, and other state forestry agencies – shows the annual spread of the disease. The story map shows that new detections occur mostly in the Coastal Plain, not in the Appalachian mountains where sassafras reaches its greatest sizes.

The Lionfish Challenge is a free summer-long (May 24-September 2, 2024) lionfish tournament open to recreational and commercial competitors of all ages around the state of Florida. Our goal remains the same — remove as many lionfish as we can in just four months. Are you up for the Challenge? See also:

The lionfish is a striking yet destructive invasive species that has found its way into the waters of North America, leaving a trail of ecological havoc in its wake. In this blog post, we delve into the alarming impact of lionfish invasion on our local marine environments and the urgent need for concerted action.

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
• September 8-12, 2024

In early December Washington Department of Fish and Wildlife (WDFW) Police received information that a Seattle market was selling live “green crabs”. The Seattle seller had bought the live green crabs from a seller in Massachusetts with the intention of selling them for crab stock and soup. The crabs were destroyed by WDFW Police officers.

The purpose of this toolkit is to assist local governments with navigating the regulatory framework associated with high-risk priority aquatic invasive species (AIS).
Note: In 2020, the National Sea Grant Law Center and project partner, Creative Resources Strategies, LLC, received funding from the U.S. Fish and Wildlife Service to conduct research on the role of municipalities in aquatic invasive species (AIS) prevention efforts. This project resulted in the development of an online toolkit to help local governments navigate the regulatory framework associated with high-risk priority AIS.

Florida is a national and global hot spot for non-native, invasive species. Because researchers and land managers in Florida have been dealing with invasive species for decades, there is an abundance of resources available to the public regarding invasive species. Sometimes, the volume of available information can be confusing. There are five different primary lists of non-native plant species that are referenced in Florida: 1. The Federal Noxious Weed List, 2. The Florida Noxious Weed List, 3. The Florida Prohibited Aquatic Plant List, 4. The Florida Exotic Pest Plant Council (FLEPPC) Plant List, and 5. The UF/IFAS Assessment of Non-Native Plants. This document aims to inform the general public, land managers, researchers, local and state policy makers, and others who seek guidance in accessing regulatory and nonregulatory non-native plant lists in the state of Florida. This publication explains the origins of the lists, meaning of inclusion on a particular list, and ways to access each of the lists.

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.
