Massachusetts Introduced Pests Outreach Project.
The Asian longhorned beetle (Anoplophora glabripennis, "ALB"), a pest of hardwood trees including maple, birch and horse chestnut, was first discovered in Worcester, Massachusetts in 2008. Since their discovery, $50 million in federal and state money has been spent to eradicate the beetle, and 25,000 infested trees in the Worcester area have been cut down in an effort to halt the spread. Use this form to report a possible Asian longhorned beetle sighting in Massachusetts or other states.

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.

The states of Oregon, Washington, and Idaho are urging people to report any feral pig sighting by calling a toll-free, public hotline, the Swine Line: 1-888-268-9219. The states use hotline information to quickly respond to a feral swine detection, helping to eradicate and curb the spread of the invasive species.

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.

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 Pest Watch is a citizen science initiative led by agencies and universities at the front line in protecting our state’s natural resources and economy from invasive species. You don't have to be an entomologist or biologist to participate in the network; the majority of network members are everyday people who keep their eyes peeled for the signs and symptoms of high priority invasive species and report them to agencies to aid in detections and rapid response. Just keep an eye out in your yard, your neighborhood, or when enjoying outdoor activities. Be aware and report what you spot—it’s simple and easy.

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.
