Invasive Species - What's New on NISIC's Site

In the early 1970s, USDA's progress in eradicating screwworm—among the deadliest and most vicious of livestock pests—was at a crossroads. Department scientists had revolutionized the country's battle against the insect by creating a new technology. The concept was simple yet profound: rear and aerially distribute masses of sterile screwworm flies in infested areas, so the resident fly populations would have increasing difficulty reproducing—and eventually breed themselves out of existence. The new approach worked so well that by 1966, USDA declared screwworm eradicated within U.S. borders.

The U.S. Department of Agriculture announced its strengthened commitment to advancing research and programmatic priorities that support pollinator health by soliciting nominations for members to serve on its newly formed USDA National Pollinator Subcommittee. The Pollinator Subcommittee will provide input on annual USDA strategic pollinator priorities and goals and will make pollinator health-related recommendations to strengthen USDA pollinator research efforts. USDA is both a major funder and conductor of pollinator research, with research initiatives spanning across five USDA mission areas.

Scientists have published a series of recommendations to enable communities and managers to minimise the impact of lionfish in the Mediterranean Sea. The invasive species was first noticed off the coast of the Lebanon in 2012, with sightings since recorded as far west as Sicily, and north into the Adriatic Sea off Croatia. More entered in 2015 due to the enlargement and deepening of the Suez Canal, with their spread unimpeded due to a lack of common predators. Researchers in the UK and Cyprus have said increasing lionfish densities – combined with the species' generalist diet and consumption of ecologically and socio-economically important fish – has the potential to result in further disruption of an already stressed marine environment. They have now published a Guide to Lionfish Management in the Mediterranean [PDF, 8.0 MB], which features a series of recommendations through which they hope lionfish populations can be managed.

The Mississippi River Delta is home to the world’s largest contiguous swath of Phragmites australis, or more commonly known as the common reed. But the plant that can grow to nearly 20 ft. and has been a critical component in stabilizing the state’s coastal erosion is not actually native to Louisiana—well, not entirely. There are multiple P. australis genotypes. P. australis subspecies (ssp.) americanus is the native subspecies in the U.S. and Canada. However, Phragmites australis ssp. australis originated in central Europe and was subsequently introduced to the U.S. where it is now considered to be one of the most problematic invasive species in North America. In a newly published study in Molecular Ecology and recently featured in an edition of The Scientist, LSU researchers collaborated with Tulane University and the U.S. Geological Survey to study the genomic bases of P. australis and to investigate what exactly makes the invasive reed grass subspecies thrive in wetlands, in comparison to its native counterpart.

The Florida Fish and Wildlife Conservation Commission (FWC) and the Southwest Florida Cooperative Invasive Species Management Area (CISMA) invite the public to participate in the 2022 Invasive Fish Roundup event, targeting freshwater invasive fish species. This event (April 28-May 1, 2022), with the weigh-in occurring on May 1 from12-3 pm at Bass Pro Shops, 10040 Gulf Center Drive, Fort Myers, Florida 33913; the weigh-in is open to the public.

The roundup is a 3-day event that is open to teams of one to four anglers, fishing from shore or boat in the Southwest Florida CISMA area (Collier, Lee, Charlotte, Hendry and Glades counties) with prizes awarded to the top team in various categories and free giveaway prizes for all participants. The goal of this event is to encourage the public to target invasive species while fishing and to promote awareness of the potential negative impacts of releasing invasive species into Florida’s waterways. This is also an opportunity for Southwest Florida CISMA and the FWC to gather information about invasive fish distribution and abundance, both of which could help with future management of invasive fish species.

Meet the Honeysweet Plum: A virus-resistant plum that ARS hopes to bring to market soon. They are large and oblong with a very sweet, flavorful taste. ARS created the Honeysweet variety using RNAi, a biotechnology method that makes them immune to the plum pox virus. Plum pox infects stone fruit trees: plums, peaches, apricots and cherries. Once infected, the fruit discolors and falls from the tree prior to maturation. There is no natural, genetic resistance to the virus.

The United States Department of Agriculture (USDA) has declared April 2022 as Invasive Plant Pest and Disease Awareness Month (IPPDAM). This national outreach month is dedicated to highlighting the impact invasive plant pests and diseases have on plant health nationwide and educates Americans about the simple actions they can take to help reduce their spread. Hungry, invasive pests threaten our nation’s food crops, gardens, and natural resources. IPPDAM aims to raise public awareness about the threat, which can devastate livelihoods, food security, and forests.

Most conservation professionals know what the “Lacey Act” is. Or do you? Since 1900, the “Lacey Act” has been the most widely known conservation law in the United States. It protects native wildlife and plants from trafficking and supports State conservation laws. And you may be surprised that it also protects against the importation of invasive or injurious species. But did you know that there was no law named “the Lacey Act”? Hence, there is a lot of confusion over what the “Lacey Act” is and isn’t. This webinar, presented by the U.S. Fish and Wildlife Service’s Injurious Wildlife Listing Coordinator, aims to clear that up. By summarizing the history from 1900, you will see how the two provisions diverged. That will segue into showing how the lesser known provision of the law is effective at preventing harmful wildlife species from being imported and causing invasions.

The U.S. Department of Agriculture's Animal Plant and Health Inspection Service (APHIS) has completed a draft environmental assessment (EA) required under the National Environmental Policy Act for its box tree moth (BTM) control program in New York. The BTM was discovered in Niagara County, New York, in July 2021. The control program proposed in the draft EA for commercial nurseries and landscaped areas where BTM has been detected includes a combination of quarantine measures, survey activities, potential box tree removal, and pesticide use.

APHIS is announcing through local newspapers in areas of New York State, where the BTM control program may occur, that a notice of availability for the draft EA will be available at https://www.regulations.gov/ (APHIS-2022-0018) for a 30-day public comment period. Anyone wishing to comment on the draft EA should submit comments on https://www.regulations.gov or send comments to the APHIS State Plant Health Director in New York State. APHIS will also post the draft EA on the APHIS website at USDA APHIS | Box Tree Moth.

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.
