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 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.

For the first time, an invasive brown treesnake population has been found on Cocos Island, an 83.1 acre atoll located 1.5 miles off the southwest coast of Guam. The brown treesnake was a major contributor to the loss of nine of 11 native forest birds and significant population declines of several native lizards, bats and other bird species on Guam. They now pose a threat to the wildlife of Cocos Island. Guam Department of Agriculture Division of Aquatic and Wildlife Resources is working with partners to better understand how many brown treesnakes are on the island and the best way to remove them.

Tennessee Department of Agriculture.

The Tennessee Department of Agriculture, United States Department of Agriculture – Animal and Plant Health Inspection Services, Tennessee Department of Health, and University of Tennessee Institute of Agriculture (UTIA) has announced the detection of the invasive Asian longhorned tick in Tennessee. The Asian longhorned tick has now spread to 11 states. The Centers for Disease Control and Prevention reports that there is no evidence that the tick has transmitted pathogens to humans or animals in the U.S. Two Asian longhorned ticks were recently found on a dog in Union County, and five were found on a cow in Roane County. In the U.S., the tick has been reported on 17 different mammal species.

Montana Department of Natural Resources and Conservation. Montana Invasive Species Council.

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.

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 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.

Oregon Department of Agriculture.

A dead spotted lanternfly (SLF), Lycorma delicatula, has been found in a shipment of planters and ceramic pots sent to Oregon from Pennsylvania. Recently, a nursery in the Corvallis area found the dead female specimen and called the Oregon Department of Agriculture (ODA) Insect Pest Prevention and Management Program (1-800-525-0137) to report. The SLF poses a threat to tree fruit and grape production. Grapes used for wine are a high value crop in Oregon, valued at more than $238 million in 2019. This invasive pest also prefers a broad range of more than 70 plant species including apples, cherry, chestnut, hops, maple, peaches, pear, pine, plum, poplar, oak, rose and walnut.

SLF was first found in North America in 2014, in Pennsylvania. It is believed to have arrived on shipments of stone from China. Since then, SLF has been detected in 11 eastern states (Connecticut, Delaware, Massachusetts, Maryland, North Carolina, New Jersey, New York, Pennsylvania, Virginia and West Virginia). If you believe you have found SLF, please notify the Oregon Department of Agriculture immediately by calling 1-800-525-0137 or email plant-entomologist@oda.state.or.us.

Asian giant hornet is the world's largest species of hornet. In December 2019, WSDA received and verified four reports of Asian giant hornet near Blaine and Bellingham. These are the first-ever sighting in the U.S. Canada had also discovered Asian giant hornet in two locations in British Columbia in the fall of 2019. If it becomes established, this hornet will have serious negative impacts on the environment, economy, and public health of Washington State. If you think you may have spotted an Asian giant hornet, report it using the Hornet Watch Report Form.

Tribal, state and local governments will join forces at Lake Roosevelt this week to combat the spread of northern pike, recently recorded just two dams away from critical Columbia River salmon habitat. “We are at a critical moment in time where northern pike have not spread into salmon habitat,” said Kelly Susewind, director of the Washington Department of Fish and Wildlife. “If northern pike move downstream, the State of Washington will consider this an environmental emergency. We need to work together to stop northern pike.”

Washington State Department of Agriculture.

On May 29, the Washington State Department of Agriculture (WSDA) reported the first confirmed sighting of an Asian giant hornet in Washington this year. On May 27, a resident near Custer, Wash. found the dead specimen while walking on a roadway. The resident submitted a photo and report using WSDA's online Hornet Watch Report Form. On May 28, WSDA entomologists concluded that the photo appeared to show an Asian giant hornet. The hornet was detected near the location of a suspected Asian giant hornet bee kill in 2019. WSDA had already planned trapping in the area and will maintain that plan to try to find any colony that may be there. The first find of the year in the United States comes just days after the British Columbian government confirmed their first detection of the year in Canada near Langley, B.C. That specimen was initially reported to authorities on May 15. Asian giant hornet is the world's largest hornet and a predator of honey bees and other insects. A small group of Asian giant hornets can kill an entire honey bee hive in a matter of hours. Visit agr.wa.gov/hornets to learn more about Asian giant hornets and the state's trapping and eradication project.

USDA. Animal and Plant Health Inspection Service.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is announcing its plans for combatting the Asian longhorned beetle (ALB) in New York, Massachusetts, and Ohio in 2020. "Just last year we declared eradication of ALB from Brooklyn and Queens in New York City, ending the city's 23-year-long battle with the beetle," said Osama El-Lissy, APHIS' Plant Protection and Quarantine Deputy Administrator. "This year, we've mapped out a sound strategy that will further our efforts to eliminate this pest from the remaining areas of this country where it still has a foothold."

Every year, APHIS evaluates and determines the most effective options to achieve ALB eradication. In 2020, the ALB program will focus on inspecting trees in quarantined areas in New York, Massachusetts, and Ohio, and removing infested trees at no cost to property owners. The program will not apply insecticide treatments this year. In addition, program officials will monitor for the beetle’s presence inside and around each area, respond to service calls, conduct training sessions for compliance agreement holders, and perform outreach.

USDA. Animal and Plant Health Inspection Service.
The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a small flock of pet chickens in Coconino County, Arizona. This is the first case of virulent Newcastle disease in Arizona. This case is believed to be connected to the current outbreak of virulent Newcastle disease in California, as tests show the virus is almost identical to the virus causing disease in California. Virulent Newcastle disease is not a food safety concern. No human cases of Newcastle disease have ever occurred from eating poultry products. In addition to practicing good biosecurity, all bird owners should report sick birds or unusual bird deaths to their veterinarian or to State veterinary officials. Additional information on biosecurity for all poultry flocks can be found at www.aphis.usda.gov/animalhealth/defendtheflock.
