The Asian Giant Hornet Public Dashboard shares detection and trapping data. Citizen scientists were able to view detections in real time, including the number of reported sightings and number of hornets confirmed by type. Coordinating this information provided input on future trapping and demonstrated the benefit of collaboration with citizen scientists. WSDA has indicated that citizen data sharing and bottle trapping efforts are crucial to protect Washington from this invasive species.

Maine Department of Agriculture, Conservation & Foresty.

The Maine Department of Agriculture, Conservation and Forestry has announced an addition to the state's invasive species list. Beech leaf disease, leading to the decline and mortality of beech trees from Ohio to southern New England, has arrived in Maine's forests. The disease was confirmed in leaf samples from a forest in Lincolnville (Waldo County) by Dr. Robert Marra of the Connecticut Agricultural Experiment Station. The Maine Forest Service is asking the public's help in identifying additional areas impacted by beech leaf disease. If you suspect you have found affected leaves submit photos using the MFS tree ailment form, email foresthealth@maine.gov, or call (207) 287-2431. Photos should include a clear shot of the underside of an affected leaf or leaves. However, please report concerns even if photos cannot be provided.

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.

Texas Parks and Wildlife Department.

The Texas Parks and Wildlife Department (TPWD) received a report in late June that an invasive silver carp had been spotted in Choctaw Creek, a Texas tributary of the Red River approximately 15 miles downstream from Lake Texoma. "These are the first reports of silver carp from Texas waters, although they have previously been found in other areas of the Red River including just downstream from Lake Texoma in Oklahoma waters in 2019," said Dan Bennett, TPWD fisheries management biologist. "Invasive carp pose a significant risk to Lake Texoma’s ecosystem and boaters and there is adequate flow and upstream river area for them to become established and reproduce in the lake if introduced."

Anyone who catches either silver or bighead carp in Texas waters is asked to report the sighting with location information and photos to AquaticInvasives@tpwd.texas.gov. Silver and bighead carp are prohibited exotic species in Texas and must be killed upon possession by beheading, gutting, gill-cutting or other means or placed on ice. Neither species can be possessed live.

Maine Department of Agriculture, Conservation, and Forestry.

The Maine Department of Agricultural, Conservation and Forestry (DACF) announced finding egg masses of the invasive spotted lanternfly (SLF) on trees in Maine communities and is urging residents to report any sign of the invasive pest. The egg masses were found on trees from Pennsylvania, where SLF is established and planted in Boothbay, Freeport, Northeast Harbor, and Yarmouth. DACF urges anyone who received goods or materials, such as plants, landscaping materials, or outdoor furniture, from a state with a known SLF infestation to carefully check the materials, including any packaging, for signs of SLF. If any life stages of SLF are found, residents should take a photo or collect the specimen and report any pest potential sightings to bugwatch@maine.gov. Residents should look for large, gray insects, about one inch long, with black spots and red underwings, or inch-long, rectangular yellowish-brown egg masses covered with a gray waxy coating.

Because no live SLF has been found in Maine, there is currently no evidence that SLF has become established. The DACF Horticulture Program has inspected all the suspect trees and asks the homeowners and landscape companies to keep an eye on the areas where egg masses were found to confirm that no live populations are present. Spotted lanternfly has not previously been found in Maine.

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.

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 to WSDA's Pest Program and, if possible, include a photo.

Kansas Department of Wildlife & Parks.

Widespread sampling for invasive crayfish had never occurred in Kansas lakes – that is, until the Kansas Department of Wildlife and Parks (KDWP) recently funded a university project focused on the freshwater crustacean. KDWP's Aquatic Nuisance Species Program and Ecological Services section funded the project with the overarching goal of establishing sampling protocols that could then be used for long-term monitoring of both native and invasive crayfish in Kansas. During capturing efforts at McPherson State Fishing Lake – one of several small waterbodies slated to be inspected in the state – university researchers collected multiple Rusty Crayfish. Rusty Crayfish have not previously been documented in the wild in Kansas, making this official "discovery" the first of its kind.

Anglers, boaters and watersport enthusiasts are encouraged to keep their eyes open for this invasive species, which can be identified by its trademark large, black-tipped claws and rust-colored spots on its upper shell. If one is discovered, freeze it in a sealed plastic bag, note the date and location of capture, and contact KDWP's Emporia Research and Survey Office at (620) 342-0658.

Washington State Recreation and Conservation Office.

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.
