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 May 11, 2021, the Animal and Plant Health Inspection Service (APHIS) and the New York State Department of Agriculture and Markets (NYS AGM) expanded the European cherry fruit fly (ECFF) quarantine to include all of Monroe County and Wayne County and a small portion of northwestern Ontario County, New York. With this expansion, the ECFF quarantine now includes all of Erie, Monroe, Niagara, Orleans, and Wayne Counties. This action is necessary to prevent the spread of ECFF to non-infested areas of the United States, while maintaining commercial cherry production and marketing within the state. The APHIS website reflects the expansion of this quarantine and contains a description of all the current federal fruit fly quarantine areas.

Arkansas Game & Fish Commission.

Anglers and hunters and other boaters who use the state's waterways are being reminded by the Arkansas Game and Fish Commission's Fisheries Division of a new regulation that took effect Jan. 1, 2021, requiring all boat drain plugs to be removed before and during trailering of vessels to and from access facilities on lakes, rivers and streams. A similar boat plug regulation was already in place in 21 other states to help stop the spread of aquatic nuisance species, and the new AGFC rule was part of an extensive list of regulations recommended by the Fisheries Division and approved by the Commission in 2020, to take effect beginning Jan. 1. Aquatic nuisance species such as silver carp, giant salvinia, zebra mussels and others continue to spread across waterbodies in Arkansas, and the AGFC has as its mission a responsibility to put mechanisms in place to slow the spread.

Arkansas Department of Agriculture.

The Arkansas Department of Agriculture is pleased to announce the release of the newly created Arkansas Feral Hog Handbook, a guide to resources available in Arkansas to assist with feral hog control and eradication. The handbook includes contact information, websites, and brief explanations of the resources offered by state and federal agencies and other entities. "The Arkansas Feral Hog Handbook was made possible through a grant funded by the United States Department of Agriculture's Natural Resources Conservation Service. We appreciate their partnership and the information provided by other Feral Hog Eradication Task Force members to make the handbook a comprehensive educational resource for Arkansans," said Arkansas Secretary of Agriculture Wes Ward.

The handbooks are being distributed to the public at locations throughout the state with assistance from partner organizations, including the Arkansas Association of Conservation Districts, University of Arkansas Cooperative Extension Service, Arkansas Game and Fish, and Arkansas Farm Bureau. Copies of the handbook can be requested at lori.scott-nakai@arkansas.gov. An online version (2020; PDF | 4.48 MB) is also available.

White-nose syndrome has been spreading through U.S. bat populations since 2006 and has caused mass die-offs in various regions of the country. The syndrome is caused by Pd (Pseudogymnoascus destructans), a fungus that invades the skin of bats while they hibernate. USDA Forest Service wildlife biologists Roger Perry and Phillip Jordan conducted a study to calculate the survival rates of tricolored bats (Perimyotis subflavus) in the Ouachita Mountains of west-central Arkansas. The research helps satisfy the need for robust estimates of population data amid the WNS outbreak. The scientists chose to study the tricolored bat because it is common across North America and has suffered substantial declines due to WNS. The research highlights the importance of maintaining and protecting small hibernation sites as they may be critical to the conservation of the tricolored bat species.

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.

Maryland Department of Natural Resources.

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.

A cozy campfire for summer days, a warm fireplace for winter evenings– the use of firewood is an "established cultural norm". However, moving firewood from place to place can have devastating consequences, as it can spread forest pests that decimate forests to collectively cost an estimated $4.2 – $14.4 billion per year. In order to better address the problem of people moving firewood and vectoring forest pests, Solano and colleagues examined trends and gaps in the existing literature on firewood and human-mediated forest pest movement in North America. The existing literature demonstrates the risk of firewood movement, but fails to address the level of awareness the public has on such risks, or the level of effectiveness of firewood regulations to prevent forest pest spread.

New York State. Governor Andew Cuomo.

Funding Supports Invasive Species Rapid Response and Control, Research, Lake Management Planning, and Aquatic Invasive Species Spread Prevention Programs. Governor Andrew M. Cuomo today announced more than $2.8 million in grants have been awarded to 42 projects that will reduce the negative impacts of invasive species through control or removal activities, research, and spread prevention. These grants are part of the State Department of Environmental Conservation's Invasive Species Grant Program and are funded by the State's Environmental Protection Fund.  

State of Wyoming.

Reflecting his goal of making Wyoming a national leader in the battle against invasive species, Governor Mark Gordon announced today he has launched an initiative to address terrestrial invasive plants in the state. The initiative will be comprised of two teams -- a Policy Team and a Technical Team, each comprised of local, state and federal government representatives, private citizens representing industry and agricultural groups, as well as scientists and practitioners. The two teams will work cooperatively to develop recommendations for the Governor in the context of a large-scale strategy for invasive species management. Terrestrial invasive species represent a significant threat to Wyoming’s forests, rangelands and agricultural lands with varying levels of impact.

Vermont Agency of Agriculture, Food, and Markets.

Many people in Vermont are encountering gypsy moths (GM) for the first time. This invasive species arrived in the United States over 100 years ago and has been expanding its range ever since. They can be significant defoliators (leaf eaters) of trees and shrubs. They prefer oak trees, but when there are a lot of caterpillars around they will eat any type of leaf, including maple and pine. Vermont has not seen an outbreak of GM since 1991. At that time a fungus called Entomophaga maimaiga became prevalent in the area and significantly decreased the GM population. But the dry weather that we’ve experienced over the last few years has not been good for fungi, and the absence of fungi has allowed the GM numbers to increase.

Indiana Department of Natural Resources.

The Indiana Terrestrial Plant Rule (312 IAC 18-3-25) designates 44 species of plants as invasive pests. This rule makes it illegal to sell, gift, barter, exchange, distribute, transport, or introduce these plants in the State of Indiana. This rule goes into effect in two stages. As of April 18, 2019, it is illegal to introduce plant species on this list not already found in Indiana. Plant species already in trade will be prohibited from sale one year later (April 18, 2020).

The Arkansas Department of Agriculture is notifying the public that a new invasive grass species, Cogongrass, has been confirmed in Arkansas for the first time. For several years botanists and land managers have been on the lookout for Cogongrass (Imperata cylindrica) in southern Arkansas. This aggressive species, native to Southeast Asia, has spread rapidly across the Deep South over the past few decades. Cogongrass is considered one of the worst invasive species in the world, causing both economic and ecological damages that impact forestry, agriculture, rangeland, and natural ecosystems.

Any sightings of Cogongrass in Arkansas should be reported to Paul Shell, the Department's Plant Inspection and Quarantine Program Manager, at paul.shell@agriculture.arkansas.gov or 501-225-1598.

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.

Georgia Department of Natural Resources. Wildlife Resources Division.

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.

Michigan Department of Natural Resources.

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 Invasive Species Awareness Week.

The mission of the New York Invasive Species Awareness Week (ISAW) is to promote knowledge and understanding of invasive species and the harm they can cause by engaging citizens in a wide range of activities across the state, and empowering them to take action to help stop the spread. This annual education campaign is comprised of various outreach initiatives and events led by partner organizations statewide. Activities include interpretive hikes, invasive plant removal, and restoration projects, displays, webinars, radio and television programming, and more.

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.

A draft integrated letter report and programmatic environmental assessment has been developed to determine the economic and environmental impacts of federal participation in state-managed watercraft inspection programs along the Upper Missouri River Basin in Montana, Wyoming, North Dakota, South Dakota and Nebraska. Public comments on the draft EA will be accepted until March 2, 2021.

The existing watercraft inspection programs are managed collaboratively by the states of Montana, Wyoming, North Dakota, South Dakota and Nebraska, where watercraft transported along highways are inspected for the presence of aquatic invasive species and decontaminated when detected. If approved, federal participation in the program would be cost-shared (50 percent) with each of the states, and would employ a regional strategy to identify locations that would provide the greatest likelihood of preventing the spread of aquatic invasive species to reservoirs operated and maintained by the Corps in the Upper Missouri River Basin.
