The Asian longhorned tick, which preys on a variety of hosts including humans and wild and domestic animals, has been found in Kentucky. This new tick is known to attack animals in large numbers and will be a concern to livestock producers, wildlife enthusiasts and pet owners. The tick has been found in small numbers on elk in Martin County and black bear in Floyd County. It was found in large numbers on a bull in Metcalfe County in the south-central part of the state. Individuals who find a usually large number of ticks on their pet or livestock should contact their local veterinarian. Those who find single ticks they think might be an Asian longhorned tick should work with their county extension agent for agriculture and natural resources to submit the sample to UK entomologists for positive identification.

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.

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.  
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).

Minnesota Department of Natural Resources.

The Minnesota Department of Natural Resources is conducting an immediate response to the capture of 51 invasive carp on the Mississippi River. The invasive carp were caught by two commercial fishing operators near La Crosse and Trempealeau, Wisconsin, during routine spring netting last weekend. In response to this discovery, the DNR is working with the U.S. Fish and Wildlife Service, the U.S. Geological Survey, the Wisconsin DNR and commercial fishing operators to conduct large-scale netting, studies of the captured carp and increased monitoring. "The location where these fish were caught is commonly netted because of concentrations of commercially valuable fish," said DNR invasive carp field lead Ben Larson. "This is the largest congregation of invasive carp we've seen this far upstream." Invasive carp have been progressing upstream since escaping into the Mississippi River in Arkansas in the 1970s. These large fish compete with native species and pose a threat to rivers and lakes.

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 make arrangements for it to be picked up by a DNR official. More information about invasive carp is available on the Minnesota DNR website.

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.

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.

Rhode Island Department of Environmental Management.

Trying to reduce the spread of invasive species in Rhode Island waters, the Department of Environmental Management (DEM) has amended the state's Freshwater Fisheries Regulations to prohibit the transport of any plant or plant part into or out of any Rhode Island waterbody on any type of boat, motor, trailer, fishing supplies, or gear. The new regulation carries a $100 fine for each violation. "Many of the aquatic invasive plants in Rhode Island can reproduce from just one small plant fragment and do not need entire root systems to successfully establish in a new spot," said Katie DeGoosh-DiMarzio, Environmental Analyst with DEM's Office of Water Resources. "Cleaning off every bit of plant from recreational gear used at one pond is essential before visiting another — this includes boats, kayaks, canoes, motors, trailers, paddles, jet skis, fishing gear, waders, water tubes, and anchors. These efforts help combat the spread of aquatic invasive species in Rhode Island waterbodies."

The Department of Environmental Management (DEM) is asking Rhode Islanders to monitor their beech trees for signs of leaf damage from Beach Leaf Disease (BLD). Early symptoms of BLD include dark striping on the tree's leaves parallel to the leaf veins and are best seen by looking upward into the backlit canopy. Drastic leaf loss occurs for heavily symptomatic leaves during the growing season and may appear as early as June, while asymptomatic and mildly symptomatic leaves show no or minimal leaf loss. BLD was detected in the Ashaway area of Hopkinton, Rhode Island, in 2020 and in coastal Massachusetts. Before these findings, the disease was only known to be in Ohio, Pennsylvania, New York, and Connecticut.

Because of the seemingly random nature of disease in Rhode Island, DEM encourages homeowners and forest landowners to monitor their beech trees and report any suspected cases of BLD on DEM's Invasive Species Sighting Report webpage. Although BLD is relatively new in the U.S. and information is limited, links to additional information about the disease and photos are posted on the Division of Forest Environment's Current Threats page. If people have further questions, they should contact a licensed arborist or email Nancy Stairs, forestry program supervisor in DEM's Division of Forest Environment, via Nancy.Stairs@dem.ri.gov.

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.

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.

On October 10, 2019, the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) in coordination with the New York State Department of Agriculture and Markets, New York State Department of Environmental Conservation, and New York City Department of Parks and Recreation announced that they have eliminated the Asian longhorned beetle (ALB) from the New York City boroughs of Brooklyn and Queens. "I am proud to say that we have eradicated Asian longhorned beetle from Brooklyn and Queens," said Greg Ibach, USDA's Under Secretary for Marketing and Regulatory Programs. "This officially marks the end of our 23-year long battle with this pest in New York City."

The Washington Invasive Species Council, state agencies and researchers are calling for a census in May to help determine the location of Scotch broom throughout the state. "We need everyone's help to size up the problem," said Justin Bush, executive coordinator of the Washington Invasive Species Council. "Without baseline information about the location and population size, we don’t have enough details to determine solutions. The information from the census will help us set short- and long-term action plans." Yellow flowered, Scotch broom is hard to miss when blooming. It can be found in 30 of Washington's 39 counties (PDF | 282 KB). While known to be spread across the state, specific locations and patch sizes are not well documented, leading to the council's call for a month-long census.

"We're asking people to send us information from their neighborhoods," Bush said. "The information can be transmitted easily to the council by using the Washington Invasives mobile app or by visiting https://invasivespecies.wa.gov/report-a-sighting/. Sightings should include a photograph of the plant that shows enough detail that the plant can be verified by an expert. A description of the size of the patch is also helpful, such as whether the patch is the size of a motorcycle, a car, a school bus or multiple school buses. Photographs also can be shared with the council on Facebook, Instagram and Twitter by using the hashtags #TheGreatScotchBroomCensus and #ScotchBroom2020Census."

Pests looking to make their homes in Washington’s urban forests may now face a stronger defense, thanks to a new resource released this this month by the state’s Invasive Species Council. The Washington State Urban Forest Pest Readiness Playbook, published in partnership with the Washington State Department of Natural Resources (DNR), contains guidelines that towns, cities, counties and urban forestry programs can follow to address the threat of forest pests, which are estimated to cost local governments across the country an estimated $1.7 billion each year. The playbook contains self-assessments and recommended actions that communities can use to prepare for pest outbreaks. Support and funding for this effort came from 2018 Farm Bill Section 10007 through the U.S. Department of Agriculture and Plant Health Inspection Service Plant Protection and Quarantine.
