Mike Dunleavy, Governor of the State of Alaska, proclaimed Alaska Invasive Species Awareness Week (June 9-15, 2024), encouraging all Alaskans and visitors to learn about, prevent, report, and contribute to control of invasive species in the state.

In the spring of 2023, the AKISP Board and Membership approved the 2023-2028 AKISP Strategic Plan. This plan is the culmination of a multi-year effort to frame goals, strategies, actions, and evaluation measures which intend to guide Partnership members activities and collaboration at statewide, regional and local levels. Many agencies and organizations participated in identifying priorities for future invasive species work in Alaska.

For homeowners or landscapers in Michigan looking to plant small to medium flowering trees this spring, consider these alternatives to Callery pear.

A species of exotic tick arrived in Ohio in 2021 in such huge numbers that their feeding frenzy on a southeastern farm left three cattle dead of what researchers believe was severe blood loss. The scientists from The Ohio State University have reported in the Journal of Medical Entomology on the state’s first known established population of Asian longhorned ticks, and are now conducting research focused on monitoring and managing these pests.

Ohioans are encouraged to help with research efforts: People who think they’ve spotted an Asian longhorned tick can email ticks@osu.edu for instructions on how to collect the specimen and send it to Ohio State scientists as part of ongoing surveillance. To date, the lab has received Asian longhorned ticks from residents of 11 Ohio counties. More information about spotting Asian longhorned ticks and preventing tick exposure is available on Ohio State’s Bite Site hosted by the College of Food, Agricultural, and Environmental Sciences Knowledge Exchange.

Invasive insect and arthropod species make for a lot of scary headlines—think emerald ash borer, spotted lanternfly, and Asian longhorned tick, just to name a few. But success stories in invasive-species response are out there. They just need to be told. One of those success stories is the eradication of the European grapevine moth (Lobesia botrana) in northern California after it was found there in 2009. A cooperative, multipronged response effort kept infestations from running wild, and it was declared eradicated in 2016, two years after the last adult moth was caught in the region. The story of this effort is recounted, along with analysis of the invasion’s dynamics, in a study published in January in the Annals of the Entomological Society of America.

The Northern Snakehead (Channa argus), a fish native to China and Russia, has become a problem invasive species in several states, including Delaware. Anyone who catches a snakehead in Delaware is encouraged to kill it and notify the Division of Fish and Wildlife.

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.
