USDA. Animal and Plant Health Inspection Service.

The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has analyzed the potential environmental effects of establishing an integrated management strategy to control cogongrass in Alabama, Georgia, Mississippi, and South Carolina. The draft environmental assessment is now available for comment. Cogongrass is an invasive exotic grass found on public and private property, along roadways, in forests, and on farmland. This federally regulated noxious weed grows rapidly, reducing forest productivity, harming wildlife habitat and ecosystems, and encroaching on pastures and hayfields. Because of cogongrass' impact on agriculture and forest industries, Congress has given APHIS funding to partner with Alabama, Georgia, Mississippi, and South Carolina to control the spread of this weed. APHIS is proposing is an integrated management strategy that uses preventive, cultural, mechanical, biological, and chemical methods to control cogongrass in key areas of its distribution. APHIS invites the public to review and comment on this environmental assessment by April 1, 2020.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is adding Eau Claire and Richland Counties in Wisconsin to the list of quarantine areas for gypsy moth (GM). The GM populations in these counties have reached the threshold to trigger the quarantine expansion. To prevent the further spread of GM, the attached Federal Order (PDF | 186 KB) establishes Eau Claire and Richland Counties in Wisconsin as quarantine areas. Effective immediately, all interstate movement of GM-regulated articles from Eau Claire and Richland Counties must be handled in accordance with the attached Federal Order. Wisconsin has established a parallel state quarantine.

Today, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) and Clemson University’s Department of Plant Industry (DPI) announced their plans for combatting the Asian longhorned beetle (ALB) in Charleston County, South Carolina. In June, APHIS and DPI confirmed the beetle is infesting trees in the county. The eradication strategy in South Carolina will be like those used for other ALB infestations in the United States. It includes establishing a quarantine, removing infested trees, and potentially using, with the landowner’s permission, a combination of tree removal and chemical treatment for trees that are within a half-mile radius of an infested tree.

If you live in the regulated area (PDF | 576 KB), please help by allowing officials access to your property to inspect and remove trees. If you live in Charleston County or nearby counties, please look for ALB and examine your trees for any damage that may be caused by the beetle, such as dime-sized exit holes in tree trunks and branches. Please take pictures and, if possible, capture suspicious insects in a durable container and freeze them, which helps to preserve the insect for identification. ALB is not harmful to people or pets. Report the insect or tree damage by calling the ALB hotline at 1-866-702-9938 or online at www.AsianLonghornedBeetle.com.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is removing 45,562.067 acres from the golden nematode (GN) regulated area in Suffolk County, New York and refining the global positioning system (GPS) points for the descriptions of the regulated area in the town of Oyster Bay in Nassau County, New York. APHIS is removing these areas based on survey results and other criteria in the "Canada and United States Guidelines on Surveillance and Phytosanitary Actions for the Potato Cyst Nematodes, Globodera rostochiensis and Globodera pallida”.

Since 2010, APHIS, working closely with the New York State Department of Agriculture and Markets (NYS AGM), has removed 1,186,693.79 acres from the GN-regulated area in New York. APHIS and NYS AGM have an active control and mitigation program in place to prevent GN from spreading from the remaining 101,955.27 acres, including 5,945 GN-infested acres in eight New York counties. The specific GN-regulated areas are on the APHIS website.

New York State Department of Environmental Conservation.

The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) today announced that although freezing temperatures will kill off adult spotted lanternflies (SLF), the public is urged to stay vigilant and report overwintering egg masses. In the fall, SLF will lay their eggs on any flat surface such as vehicles, firewood, outdoor furniture, stone or other items which can be inadvertently transported to new areas. If this insect becomes established in New York, it could impact New York's forests, agricultural and tourism industries. "To date, there has not been a documented spotted lanternfly infestation in New York, but I encourage the public to stay aware and be ready to report egg masses or other signs of this insect to help prevent infestations," said DEC Commissioner Basil Seggos.

Assistance from the public is crucial in limiting the movement of SLF and protecting New York's natural resources. DEC and DAM are urging the public to inspect outdoor items such as vehicles, outdoor furniture and camping equipment for egg masses or insects, and report any sightings by sending photos and location information to spottedlanternfly@dec.ny.gov. Anyone that visits locations of SLF quarantines in other states should look for and remove insects and egg masses on items before leaving those areas. For more information, please visit DEC's spotted lanternfly webpage.

The Maryland Department of Agriculture has confirmed the first spotted lanternfly hatch of 2020. The first instar nymph of the season was reported by a department employee while surveying for the pest in the upper northeast corner of Cecil County near the Pennsylvania border.

See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information. For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.

Montana Invasive Species Council.

Montana’s economy could see more than $230 million in annual mitigation costs and lost revenue if invasive mussels become established in the state, according to a report released by the Montana Invasive Species Council (MISC). Commissioned by MISC and completed by the University of Montana Flathead Biological Station, the economic impact study provides “a snapshot of projected direct costs to affected stakeholders dependent on water resources,” said Bryce Christiaens, MISC chair. “It does not reflect the total economic impact to the state, which would be considerably higher.” View a one-page fact sheet (PDF | 484 KB) or the full report (PDF | 4.0 MB).

Georgia Department of Natural Resources. Wildlife Resources Division.

The Georgia Department of Natural Resources' Wildlife Resources Division confirmed someone found a northern snakehead in early October in a pond on private property in Gwinnett County, marking the first time the invasive fish has been found in the state. Fishermen who find a northern snakehead should take pictures, note where it was caught and then report it.

Minnesota Department of Natural Resources.

Beginning Monday, Oct. 25, the Minnesota Department of Natural Resources will lead a second intensive invasive carp removal effort in Pool 8 of the Mississippi River near La Crosse, Wis. Thirty-four silver carp were captured in Pool 8 during the first interagency carp removal operation in April. The innovative Modified Unified Method (MUM) combines netting and herding techniques to drive and concentrate invasive carp from a large area of water into a small zone for removal. The DNR is conducting this work in partnership with the Wisconsin Department of Natural Resources, the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service.

Anglers are reminded that invasive carp captures must be reported to the DNR immediately. Call 651-587-2781 or email invasivecarp.dnr@state.mn.us. Take a photo and transport the carp to the nearest DNR fisheries office or arrange for it to be picked up by a DNR official.

Montana Department of Agriculture.

The Montana Department of Agriculture (MDA) has issued an emergency quarantine order to protect against the introduction and spread of the emerald ash borer (EAB), a destructive wood-boring beetle that has already killed millions of ash trees in North America. The order was motivated by the removal of federal domestic quarantine regulations by the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS). "It is important that we remain vigilant and do everything in our power to make sure that the emerald ash borer doesn’t find a way into Montana," said MDA Director Mike Foster. "This quarantine order protects the green ash woodland resources in eastern Montana that provide habitat for many wildlife species as well as economic benefits to livestock producers and rural communities."

Montana’s emergency quarantine order restricts EAB from entering the state in any form, as well as the movement of live ash trees, parts of ash trees capable of harboring live EAB, and any other articles determined potentially hazardous. MDA will accept public comment regarding the quarantine order until February 26, 2021.

The Montana and Washington invasive species councils have joined forces to stop wild pigs from crossing borders. The two councils issued a report with recommendations and best management practices aimed at helping federal, state, provincial and local landowners manage wild pigs in the western United States and Canada. "Wild pig populations are expanding in the western provinces of Canada and in the United States." said Stephanie Criswell, coordinator of the Montana Invasive Species Council. "We are at a unique point in time where we can work together to prevent Canadian wild pigs from spreading across borders into unaffected states like Montana."

In early 2020, the two invasive species councils convened a working group of more than 40 federal, state and Canadian feral swine experts to discuss challenges and opportunities to prevent feral swine along interstate and international borders. Finalized this month, the report includes 22 recommendations that address five strategic areas of feral swine management. Recommendations include standardizing communications to the public, expanding monitoring networks by partnering with non-traditional organizations such as hunting groups, and formalizing notification protocols for reports that will be shared between state and provincial authorities along the international border. The complete report can be found at misc.mt.gov.

Wildlife officials are warning Georgia boat owners to be on the lookout for an invasive species that could cause millions of dollars in damages throughout the state. The Georgia Department of Natural Resources says zebra mussels, an eastern European species that is considered invasive, were found on a boat taken to Lake Lanier after being used on the Tennessee River near Chattanooga.

Montana Fish, Wildlife & Parks.

On Sunday, June 27, watercraft inspection stations in eastern Montana intercepted two boats entering the state carrying invasive mussels, making it the 35th and 36th mussel-fouled boats intercepted this year. This surpasses the total number of 35 mussel-fouled boats intercepted in 2020.

Fish, Wildlife & Park staff reminds anyone transporting motorized or nonmotorized boats into Montana that an inspection is required before launching, and stopping at ALL open watercraft inspection stations is required. Failing to stop at an inspection station can result in a fine of up to $500. Many residents of western states, including Montana, are buying boats out of the Midwest or southwestern U.S., where invasive mussels are common. The record number of interceptions is a reminder for people purchasing boats from other states to clean, drain and dry the vessel.

You could say that preventing the spread of aquatic invasive species (AIS) is a team sport. While it takes the professional efforts of natural resource managers, AIS specialists and others in the environmental field, it also takes the cooperation of the public. Yet for community members to take necessary actions, they must first be aware of the negative impacts AIS can have and how to stop their spread. Communicating with them about AIS in an effective way is vital.

New research from Wisconsin Sea Grant Aquatic Invasive Species Outreach Specialist Tim Campbell, University of Wisconsin-Madison Associate Professor Bret Shaw and consultant Barry T. Radler sheds new light on such communication. The researchers analyzed which communication strategies are most effective and which may pose unintended problems. The team's findings were published online Aug. 14 in the journal Environmental Management (“Testing Emphasis Message Frames and Metaphors on Social Media to Engage Boaters to Learn about Preventing the Spread of Zebra Mussels”).

Invasive species cause biodiversity loss and about $120 billion in annual damages in the U.S. alone. Despite plentiful evidence showing that invasive species can change food webs, how invaders disrupt food webs and native species through time has remained unclear. Now, thanks to a collaborative study conducted by researchers representing the University of Montana's Flathead Lake Biological Station (FLBS), U.S. Geological Survey (USGS), and Montana Fish, Wildlife & Parks, there is new insight into how invasive species progressively affect native food webs.

For landscapes plagued by autumn olive or entangled in oriental bittersweet, a new website offers help identifying and managing woody invasive plants like these. WoodyInvasives.org, developed by the Woody Invasives of the Great Lakes Collaborative, contains a wealth of information about how to distinguish woody invasive species from similar beneficial plants, an interactive map showing how these species are regulated by Great Lakes jurisdictions, detailed management approaches and noninvasive woody plant ideas for gardeners and landscape designers. "We developed the WIGL Collaborative website to help people learn to identify the woody invasive plants around them and to feel empowered to start controlling them on their properties or in their favorite green places," said Clair Ryan, coordinator of the Midwest Invasive Plant Network, the organization leading the effort.

New York State Department of Agriculture and Markets.

The New York State Departments of Agriculture and Markets (AGM) and Environmental Conservation (DEC), and the Office of Parks, Recreation, and Historic Preservation (Parks) today announced an innovative effort to combat the spread of Spotted Lanternfly (SLF) in New York State. A new online interface will allow volunteer members of the public to assist in surveying for SLF and tracking associated data. The program encourages broader surveying for SLF and increased public awareness of this invasive pest, following confirmed finds of SLF in New York State this past fall.

The new initiative, which launched this week, invites volunteers to sign up to survey a specific area, or grid, of land on iMapInvasives. This online, GIS-based data management system is used to assist citizen scientists and natural resource professionals to protect against the threat of invasive species. Volunteers will also enter data from their survey work into iMapInvasives. More information about the program, including upcoming webinars, can be found at https://www.nyimapinvasives.org/slf.

New York State Department of Environmental Conservation.

New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos today encouraged anglers in the Delaware River to be on the lookout for northern snakehead, an invasive fish native to Southeast Asia. A northern snakehead was recently caught in the Callicoon area of the Delaware River. Given the right environmental conditions, this invasive species can prey on and compete with other fish, upsetting the natural balance of local ecosystems. "Northern snakeheads are listed federally as injurious wildlife, and New York State law prohibits their live possession," Commissioner Seggos said. "Any snakehead caught should be killed immediately and not released back into the water." In the event an angler catches a northern snakehead, DEC advises anglers to report the catch to the regional NYS DEC fisheries office, DEC's Invasive Species Bureau at isinfo@dec.ny.gov or (518) 402-9425, or submit a report through iMapinvasives.
