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

A portion of Los Angeles County has been placed under quarantine for the Tau fruit fly (Zeugodacus tau group) following the detection of more than 20 flies in the unincorporated area of Stevenson Ranch, near the city of Santa Clarita.

This the first Tau fruit fly quarantine ever in the Western Hemisphere. The fly is native to Asia and is a serious pest for agriculture and natural resources, with a very wide host range, including numerous fruits and vegetables as well as a select range of native plants in California.

The Pennsylvania Fish and Boat Commission (PFBC) has issued a strong advisory to encourage anglers who catch invasive Northern Snakeheads in the lower Susquehanna River, and elsewhere in the Commonwealth, to report and dispose of any fish caught. This advisory follows multiple Northern Snakehead captures in Conowingo Reservoir by anglers and natural resource agency biologists this summer, including the first evidence of Northern Snakehead reproduction in the reservoir.

The high winds, heavy rains and storm tides caused by hurricanes and tropical storms can rapidly change the landscape of an area affected by a storm. Hurricane-related flooding can also result in a slow transformation of ecosystems found on land and in water, as floodwaters can carry invasive wildlife and plant species into new regions, accelerating their spread.

The U.S. Department of Agriculture (USDA) declares August as “Tree Check Month” for the Asian longhorned beetle (ALB). USDA and its partners are asking the public to check their trees for this invasive insect and the damage it causes and limit the movement of ALB-host materials, such as firewood. August is the most important time of year to look for the beetle because it is when people are most likely to see adult beetles.

Research and commerce use a two-pronged ‘fork’ approach to deal with invasive fish. As many anglers know, carp are not welcome when found dangling from the hook. Classified by U.S. government as an invasive species and known colloquially as a “trash fish,” carp can take over and devastate every watery environment they enter. They’re not particularly well known in this country as good eating fish, either. To help curb the numbers of invasive fish, researchers and commerce are using a two-pronged ‘fork’ approach to deal with the invasive fish.

The Florida Python Challenge® (August 4-15, 2023) is an exciting conservation effort which helps protect the rare Everglades habitat and the animals that live there from these invasive, nonnative snakes.

The Lionfish Challenge is a free summer-long (June 1 - October 1, 2023) 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 U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is continuing to advance animal disease preparedness and response through its Farm Bill animal health programs. APHIS is seeking project proposals for the National Animal Disease Preparedness and Response Program (NADPRP) and the National Animal Health Laboratory Network (NAHLN). The agency is also announcing its next round of purchases for the National Animal Vaccine and Veterinary Countermeasures Bank (NAVVCB). The 2018 Farm Bill provided funding for these programs as part of an overall strategy to help prevent animal pests and diseases from entering the United States and reduce the spread and impact of potential disease incursions through advance planning and preparedness. Projects selected for funding will be awarded in FY 2024.

APHIS will make available up to $23.5 million in funds for NADPRP and NAHLN. NADPRP proposals must be submitted by October 20, 2023, and NAHLN proposals must be submitted by October 27, 2023.

Biological invasions are a major threat to ecosystems, biodiversity, and human well-being, resulting in ecosystem degradation and causing economic costs in the multi-trillions of euros globally. A study led by McGill University sheds light on the stark economic cost resulting from biological invasions in the European Union (EU). Most invasive alien species are not adequately assessed for their actual and potential economic impacts therefore most cost estimates are grossly underestimated, say the researchers. To fill this gap, the team quantified the economic costs of biological invasions to the European Union, while estimating future invasion costs using predictive models.

On June 1, a new regulation was published in the Delaware Register of Regulations (Volume 26, Issue 12) listing potbellied pigs and feral swine of any kind as invasive. The Delaware Department of Agriculture (DDA) is providing a 30-day grace period for potbellied pig owners to apply for an Invasive Animal Permit. Owners have until August 12 to submit an application and comply with 3 DE Admin. Code 906 Possession, Sale, or Exhibition of Non-Native and Invasive Animal Species.
