Pennsylvania Fish and Boat Commission.

The Pennsylvania Fish and Boat Commission (PFBC) is urging anglers to report and dispose of any invasive Northern Snakehead fish that may be caught in the lower Susquehanna River. This advisory follows the documented movement of 21 Northern Snakeheads past the Conowingo Dam into the Conowingo Pool, a 14-mile-long section of the Susquehanna River located between the Conowingo Dam in Maryland and the Holtwood Dam in Pennsylvania. Anglers are reminded that possession, transport, and importation of a live snakehead is unlawful in both Pennsylvania and Maryland. Any of these invasive fish that are caught should be killed and disposed of properly or consumed. Anglers who suspect they have caught a snakehead are encouraged to NOT release it, and report it to the PFBC at (610) 847-2442 or by sending an email to tgrabowski@pa.gov. For more information on Northern Snakeheads in Pennsylvania, including an identification guide, visit the PFBC snakehead resource page.

Colorado Parks and Wildlife.

All known feral swine have been eliminated from Colorado thanks to a near 15-year state and federal partnership comprised of the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) Wildlife Services (WS), the USDA Forest Service (FS), Colorado Parks and Wildlife (CPW) and the Colorado Department of Agriculture (CDA). The partnership formed in the early 2000s as a task force to manage invasive feral swine, which root up crops and pastures causing billions in damage nationwide each year. Feral swine also spread disease to livestock, wildlife and humans. Ground-nesting birds and other wildlife are easy prey for feral swine. And the swine put native wildlife at risk by competing for resources and destroying habitats and ecosystems. 

You can help keep Colorado free of feral swine:

  • Spread the word that in Colorado it’s illegal to possess, transport or release feral swine, wild swine species or hybrids.
  • Report sightings of feral swine or transportation activities to USDA Wildlife Services at 1-866-4-USDA-WS (1-866-487-3297) or Colorado Parks and Wildlife at 303-297-1192.
  • Get more information at the National Feral Swine Damage Management Program.

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.

Massachusetts Department of Agricultural Resources.

The Massachusetts Department of Agricultural Resources (MDAR) today announced that it has identified two dead specimens of the spotted lanternfly (SLF) in Massachusetts communities, and is urging residents to report any sign of the invasive pest. The specimens were recovered in the towns of Milford and Norwood, and were brought into Massachusetts on materials shipped from Pennsylvania counties currently under a spotted lanternfly quarantine. Additionally, MDAR was recently notified that nursery stock with spotted lanternfly egg masses and adults may have been unintentionally imported and planted in several parts of Massachusetts.

MDAR is urging anyone who has 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 spotted lanternfly. Currently, there are known introductions of SLF in Connecticut, Delaware, Maryland, New Jersey, New York, Pennsylvania, Virginia, and West Virginia. If any indication of SLF is found, residents should take a photo or collect the specimen, and report any potential sightings of the pest using MDAR’s online reporting form. 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.

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.

Pennsylvania Department of Agriculture.

Pennsylvania Agriculture Secretary Russell Redding today announced that twelve counties have been added to Pennsylvania's Spotted Lanternfly quarantine zone ahead of the 2020 spring hatch. With this addition, the quarantine (PDF | 506 KB) for this invasive pest is now at 26 counties. The new dozen counties are not completely infested, but rather have a few municipalities with a known infestation (PDF | 803 KB) which led to a quarantine being placed on the entire county out of an abundance of caution. Allegheny, Beaver, Blair, Columbia, Cumberland, Huntingdon, Juniata, Luzerne, Mifflin, Northumberland, Perry, and York have been added to the quarantine for 2020.

Pennsylvania Department of Conservation and Natural Resources.

Pennsylvania Department of Conservation and Natural Resources Secretary Cindy Adams Dunn announced that the department is launching an effort at nine state parks this summer to help prevent the spread of aquatic invasive species, and get boaters involved in invasive species detection. "Boats, motors, and trailers have ideal hiding spots where species may attach, and be transported to new locations," Dunn said. "Boaters must be involved in helping us protect state park waters from invaders, to benefit our environment and avoid very costly measures to treat lakes once these non-native species take hold." Starting this week, DCNR staff will be doing voluntary boat and trailer checks at boat launches on park lakes, handing out informational brochures and demonstrating how to do an inspection.

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.

Massachusetts Department of Agricultural Resources.

The Massachusetts Department of Agricultural Resources (MDAR) announced today that a single dead specimen of the invasive pest known as spotted lanternfly (Lycorma delicatula) was reported and confirmed at a private residence in Boston. As a result, MDAR is urging the public to check for signs of spotted lanternfly adults in any potted plants that they may have received over the holiday season and to report any potential sightings of this pest on MDAR's online reporting form by taking photographs and collecting a specimen if possible. Residents should look for large, gray insects, about one inch long, with black spots and red underwings.

Pennsylvania Sea Grant College Program.

Aquatic invasive species (AIS) pose a significant threat to Pennsylvania’s economy, freshwater resources, and native aquatic species. Pennsylvania Sea Grant announces 'there’s an app for that' with the launch of "PA AIS," a new, easy-to-use smart phone application. The "PA AIS" app is now available in the Apple App Store, with an Android version anticipated. The "PA AIS" app can be used in airplane mode or in areas outside of coverage, making it ideal for use in the field. Users can identify AIS and submit a report to the state AIS coordinator, including the location, severity, and photos of the suspected infestation. Illustrations help users learn more about each species to ensure accurate identification in the field. Prevention tips help educate freshwater enthusiasts such as anglers and boaters about the steps they can take to properly clean gear and ensure that AIS are not transported from one water body to another.

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.

On May 14, Director Reilly signed a Memorandum of Agreement with the Department of the Navy and the U.S. Fish and Wildlife Service. The MOA provides for continuity of operations for the USFWS and the USGS with construction of new office and lab facilities on the Guam National Wildlife Refuge in conjunction with DOD’s construction of a Marine Corps firing range. "The USGS has a long history of collaborating with the Department of Defense in support of U.S. facilities and force readiness in the INDOPACOM Area of Responsibility. One of our signature efforts ongoing today is a collaboration with DOD, the U.S. Fish and Wildlife Service, and the local government in minimizing the impacts of the invasive Brown Treesnakes (BTS) and improving BTS controls on military lands on Guam," said Jim Reilly, director of the USGS.

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.
