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 firstname.lastname@example.org. For more information on Northern Snakeheads in Pennsylvania, including an identification guide, visit the PFBC snakehead resource page.

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 Division of Fisheries and Wildlife.
On August 27, an angler caught a northern snakehead from Reservoir Pond in Canton, Massachusetts. After obtaining and analyzing the specimen, MassWildlife confirmed this fish was a snakehead, an invasive species in Massachusetts. This fish was most likely released by a pet owner when it grew too large for its aquarium. Possession and liberation of snakeheads are both illegal in Massachusetts. Transferring exotic fish into local waterways can cause a host of problems, including competition with native species and spread of disease. This recent catch is the fifth confirmed snakehead documented in Massachusetts since 2002. All snakeheads found in Massachusetts were adults, and MassWildlife has found no evidence of reproduction at any of the locations where the snakeheads were caught.
Anglers may confuse snakeheads with other native species like bowfin. Anyone who captures a fish that can be confidently identified as a snakehead should keep the fish, kill it, and report it to MassWildlife by emailing email@example.com or calling (508) 389-6300. MassWildlife encourages anglers who are less certain about the species of fish they have caught to send photos showing various angles of the fish. Under no circumstance should a suspected snakehead be transported to another location until identification is confirmed.
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.
Minnesota Department of Natural Resources.
Beginning Monday, Oct. 25, the Minnesota Department of Natural Resources will lead a second intensive invasive carp removal effort in Pool 8 of the Mississippi River near La Crosse, Wis. Thirty-four silver carp were captured in Pool 8 during the first interagency carp removal operation in April. The innovative Modified Unified Method (MUM) combines netting and herding techniques to drive and concentrate invasive carp from a large area of water into a small zone for removal. The DNR is conducting this work in partnership with the Wisconsin Department of Natural Resources, the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service.
Anglers are reminded that invasive carp captures must be reported to the DNR immediately. Call 651-587-2781 or email firstname.lastname@example.org. Take a photo and transport the carp to the nearest DNR fisheries office or arrange for it to be picked up by a DNR official.

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.

A parasitoid wasp that is the natural enemy of a fly known as the spotted-wing drosophila could be a good friend to growers. Washington State University researchers recently confirmed the discovery of the potentially beneficial wasp in the United States for the first time. The drosophila flies cause major damage to several Washington crops, especially sweet cherries and berries. The wasp, which lays its eggs in the flies, could be a means of controlling their spread.

You could say that preventing the spread of aquatic invasive species (AIS) is a team sport. While it takes the professional efforts of natural resource managers, AIS specialists and others in the environmental field, it also takes the cooperation of the public. Yet for community members to take necessary actions, they must first be aware of the negative impacts AIS can have and how to stop their spread. Communicating with them about AIS in an effective way is vital.
New research from Wisconsin Sea Grant Aquatic Invasive Species Outreach Specialist Tim Campbell, University of Wisconsin-Madison Associate Professor Bret Shaw and consultant Barry T. Radler sheds new light on such communication. The researchers analyzed which communication strategies are most effective and which may pose unintended problems. The team's findings were published online Aug. 14 in the journal Environmental Management (“Testing Emphasis Message Frames and Metaphors on Social Media to Engage Boaters to Learn about Preventing the Spread of Zebra Mussels”).

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.

The PA Department of Agriculture added Japanese Barberry, or Berberis thunbergii, to a list of noxious weeds — plants that cannot be legally sold or cultivated in the state. The popular, non-native, ornamental shrub forms dense, prickly thickets that crowd out plants and disrupt native ecosystems. It is also thought to harbor black-legged ticks that spread lyme disease. The ban on sale and cultivation took effect October 8, 2021. Enforcement of the ban will be phased in over two years to allow time for nurseries to eliminate it from their stock, find non-harmful alternatives, and develop seedless, sterile varieties that pose less threat to the environment and agriculture. Landscape and nursery businesses will receive notices of the timeline, procedures and exemption process for sterile varieties. Property owners should consider eliminating the shrubs on their land.
Effective October 8, 2021, the department added two other plants to the noxious weed list: garlic mustard, Alliaria petiolata, and Japanese stiltgrass, Microstegium vimineum. These plants are generally not sold in nurseries but are invasive and common in Pennsylvania. Landowners with these plants on their property are encouraged to remove them.
