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

Garlic mustard (Alliaria petiolate) is a highly destructive invader in North America. As well as hindering the survival of native plants, it poses a particular threat to the survival of the rare West Virginia white butterfly (Pieris virginiensis).

After being disbanded in 2019, newly appointed members of the Invasive Species Advisory Committee (ISAC) gathered this week to discuss strategies to prevent, eradicate and control invasive species, which impose substantial costs on society and cause damages that impact the global economy, including an estimated $120 billion in environmental damages and losses annually in the United States.

The Maryland Department of Agriculture expanded its spotted lanternfly quarantine to include a total of 17 counties and the city of Baltimore. The quarantine is effective immediately, and restricts the movement of regulated materials that might contain the spotted lanternfly in any of its life stages, including egg masses, nymphs, and adults. 

This little piggy went to market, this little piggy stayed home, this little piggy had roast beef and this little piggy…caused major damage to agricultural crops and the environment. Okay, so that is not exactly how the children’s nursery rhyme goes, but this is a true story for farmers and landowners. In fact, wild pigs cause millions of dollars’ worth of damage each year.

From the forefront of forest research, the Northern Research Station invites you inside the largest forest research organization in the world — the USDA's Forest Service. In each podcast episode, you’ll hear stories, interviews, and special in-depth anthologies of the science that's studying, questioning, and solving some of today's most compelling forest issues.

Non-native invasive insects and pathogens are causing significant ecological damage to forests worldwide.  The first season explores biological invasions — and their repercussions — in the Midwest and the Northeast. The second season examines tree breeding and selection to promote resistance to invasive insects and diseases.

Recreational boats are important vectors of spread of aquatic invasive species (AIS) among waterbodies of the United States. To limit AIS spread, state and county agencies fund watercraft inspection and decontamination stations at lake access points. Researchers present a model for determining how a state planner can efficiently allocate inspection resources to county managers, who independently decide where to locate inspection stations.

This resolution addresses invasive species management and adds substantial new policy, including: a call to address the destructive relationship between invasive grasses and wildfires; mechanisms to enhance regional invasive species research, planning, and coordination; and recommendations to Congress and federal agencies on improving invasive species management on federal lands and supporting state-led management efforts.

WGA resolutions are in effect for three years and then expire or are renewed. All WGA resolutions are available on their  Resolutions page.

The New York State Department of Environmental Conservation (DEC) and the New York State Canal Corporation continue to implement a comprehensive effort, including a rapid response plan [PDF, 1.73 MB], to combat the potential spread of the round goby, an aquatic invasive species (AIS), to the Lake Champlain Basin following the discovery of the fish in the Hudson River near the city of Troy in July 2021. Aquatic invasive species can out-compete native fish species, disrupting ecosystems and damaging local economies dependent on recreation.

It is now illegal to sell, grow, or plant Callery pear (also known as Bradford pear) in Ohio because of its invasive qualities and likelihood to cause economic or environmental harm. There is no requirement for the removal of existing plants, but the Ohio Department of Natural Resources (ODNR) Division of Forestry encourages control and removal to benefit native forest ecosystems.

Assays of environmental DNA — traces of genetic material found in air, soil, and water — may improve scientists’ ability to detect bat roosts and track the spread of white-nose syndrome, a disease caused by a killer fungus spread easily in the close quarters of hibernacula. In this research, scientists experienced success in detecting bats in field collected samples of environmental DNA, though the technology is still in the experimental stage.
